‘Negative Capacitance’ Could Bring More Efficient Transistors

HPC Wire - Mon, 12/18/2017 - 12:34

WEST LAFAYETTE, Ind., Dec. 18, 2017 — Researchers have experimentally demonstrated how to harness a property called negative capacitance for a new type of transistor that could reduce power consumption, validating a theory proposed in 2008 by a team at Purdue University.

The researchers used an extremely thin, or 2-D, layer of the semiconductor molybdenum disulfide to make a channel adjacent to a critical part of transistors called the gate. Then they used a “ferroelectric material” called hafnium zirconium oxide to create a key component in the newly designed gate called a negative capacitor.

Capacitance, or the storage of electrical charge, normally has a positive value. However, using the ferroelectric material in a transistor’s gate allows for negative capacitance, which could result in far lower power consumption to operate a transistor. Such an innovation could bring more efficient devices that run longer on a battery charge.

Hafnium oxide is now widely used as the dielectric, or insulating material, in the gates of today’s transistors. The new design replaces the hafnium oxide with hafnium zirconium oxide, in work led by Peide Ye, Purdue’s Richard J. and Mary Jo Schwartz Professor of Electrical and Computer Engineering.

“The overarching goal is to make more efficient transistors that consume less power, especially for power-constrained applications such as mobile phones, distributed sensors, and emerging components for the internet of things,” Ye said.

Findings are detailed in a research paper published on Dec. 18 in the journal Nature Nanotechnology.

The original theory for the concept was proposed in 2008 by Supriyo Datta, the Thomas Duncan Distinguished Professor of Electrical and Computer Engineering, and Sayeef Salahuddin, who was a Purdue doctoral student at the time and is now a professor of electrical engineering and computer sciences at the University of California, Berkeley.

The paper’s lead author was Purdue electrical and computer engineering doctoral student Mengwei Si. Among the paper’s co-authors are Ye; Ali Shakouri, the Mary Jo and Robert L. Kirk Director of Purdue’s Birck Nanotechnology Center and a professor of electrical and computer engineering; and Muhammad A. Alam, the Jai N. Gupta Professor of Electrical and Computer Engineering, who made critical and wide-ranging contributions to the theory describing the physics behind negative capacitance devices.

Transistors are tiny switches that rapidly turn on and off, enabling computers to process information in binary code. Properly switching off is of special importance to ensure that no electricity “leaks” through. This switching normally requires a minimum of 60 millivolts for every tenfold increase in current, a requirement called the thermionic limit. However, transistors that harness negative capacitance might break this fundamental limit, switching at far lower voltages and resulting in less power consumption.

New findings demonstrate the ferroelectric material and negative capacitance in the gate results in good switching in both the on and off states. The new design achieves another requirement: for the transistors to switch on and off properly they must not generate a harmful electronic property called hysteresis.

The negative capacitance was created with a process called atomic layer deposition, which is commonly used in industry, making the approach potentially practical for manufacturing.

The research is ongoing, and future work will explore whether the devices switch on and off fast enough to be practical for ultra-high speed commercial applications.

“However, even without ultrafast switching, the device could still have a transformative impact in a broad range of devices that may operate at lower frequency and must operate with low power levels,” Ye said.

Portions of the research were based at the Birck Nanotechnology Center in Purdue’s Discovery Park. The work was funded by the U.S. Air Force Office of Scientific Research, National Science Foundation, Army Research Office and Semiconductor Research Corporation.

The work was performed by researchers from Purdue, the National Nano Device Laboratories in Taiwan, and National Laboratory for Information Science and Technology of Tsinghua University in Beijing. A complete listing of the paper’s co-authors is contained in the abstract.

Intel Unveils Industry’s First FPGA Integrated with High Bandwidth Memory Built for Acceleration

HPC Wire - Mon, 12/18/2017 - 11:13

Dec. 18, 2017 — Intel today announced the availability of the Intel Stratix 10 MX FPGA, the industry’s first field programmable gate array (FPGA) with integrated High Bandwidth Memory DRAM (HBM2). By integrating the FPGA and the HBM2, Intel Stratix 10 MX FPGAs offer up to 10 times the memory bandwidth when compared with standalone DDR memory solutions. These bandwidth capabilities make Intel Stratix 10 MX FPGAs the essential multi-function accelerators for high-performance computing (HPC), data centers, network functions virtualization (NFV), and broadcast applications that require hardware accelerators to speed-up mass data movements and stream data pipeline frameworks.

In HPC environments, the ability to compress and decompress data before or after mass data movements is paramount. HBM2-based FPGAs can compress and accelerate larger data movements compared with stand-alone FPGAs. With High Performance Data Analytics (HPDA) environments, streaming data pipeline frameworks like Apache* Kafka and Apache Spark Streaming require real-time hardware acceleration. Intel Stratix 10 MX FPGAs can simultaneously read/write data and encrypt/decrypt data in real-time without burdening the host CPU resources.

“To efficiently accelerate these workloads, memory bandwidth needs to keep pace with the explosion in data” said Reynette Au, vice president of marketing, Intel Programmable Solutions Group. “We designed the Intel Stratix 10 MX family to provide a new class of FPGA-based multi-function data accelerators for HPC and HPDA markets.”

The Intel Stratix 10 MX FPGA family provides a maximum memory bandwidth of 512 gigabytes per second with the integrated HBM2. HBM2 vertically stacks DRAM layers using silicon via (TSV) technology. These DRAM layers sit on a base layer that connects to the FPGA using high density micro bumps. The Intel Stratix 10 MX FPGA family utilizes Intel’s Embedded Multi-Die Interconnect Bridge (EMIB) that speeds communication between FPGA fabric and the DRAM. EMIB works to efficiently integrate HBM2 with a high-performance monolithic FPGA fabric, solving the memory bandwidth bottleneck in a power-efficient manner.

Intel is shipping several Intel Stratix 10 FPGA family variants, including the Intel Stratix 10 GX FPGAs (with 28G transceivers) and the Intel Stratix 10 SX FPGAs (with embedded quad-core ARM processor). The Intel Stratix 10 FPGA family utilizes Intel’s 14 nm FinFET manufacturing process and incorporates state-of-the-art packaging technology, including EMIB.

Australia Commits $70 Million for Next-Generation NCI Supercomputer

HPC Wire - Mon, 12/18/2017 - 10:23

Dec. 18, 2017 — The Board of Australia’s National Computational Infrastructure (NCI), based at The Australian National University (ANU), welcomes the Australian Government’s announcement that it will invest $70 million to replace Australia’s highest performance research supercomputer, Raijin, which is rapidly nearing the end of its service life.

The funding, through the Department of Education and Training, will be provided as $69.2 million in 2017-18 and $800,000 in 2018-19.

Chair of the NCI Board, Emeritus Professor Michael Barber, said NCI was crucial to Australia’s future research needs.

“This announcement is very welcome. NCI plays a pivotal role in the national research landscape, and the supercomputer is the centrepiece of NCI’s renowned and tightly integrated, high-performance computing and data environment,” he said.

“The Government’s announcement is incredibly important for the national research endeavour.

“It means NCI can continue to provide Australian researchers with a world-class advanced computing environment that is a fusion of powerful computing, high-performance ‘big data’, and world-leading expertise that enables cutting-edge Australian research and innovation.

“The NCI supercomputer is one of the most important pieces of research infrastructure in Australia.  It is critical to the competitiveness of Australian research and development in every field of scientific and technological endeavour, spanning the national science and research priorities.”

ANU Vice-Chancellor Professor Brian Schmidt said the funding would ensure NCI remains at the centre of Australia’s research needs.

“The new NCI supercomputer will be a valuable tool for Australian researchers and industry, and will be central to scientific developments in medical research, climate and weather, engineering and all fields that require analysis of so-called big data, including, of course, astronomy,” Professor Schmidt said.

Australia’s Chief Scientist Dr Alan Finkel said high-performance computing is a national priority.

“Throughout our consultations to develop the 2016 National Research Infrastructure Roadmap the critical importance of Australia’s two high performance computers was manifestly clear,” Dr Finkel said.

“Our scientific community will be overwhelmingly delighted by the Australian Government’s decision today to support the modernisation of the NCI computer hosted at ANU.”

The announcement of funding ensures researchers in 35 universities, five national science agencies, three medical research institutes, and industry will benefit from a boost in computational horsepower, enabling new research that is more ambitious and more innovative than ever before once the new supercomputer is commissioned in early 2019.

NCI anticipates the resulting supercomputer will be ranked in the top 25 internationally.

The Australian Government’s 2016 National Research Infrastructure Roadmap specifically recognised the critical importance of such a resource, and the need for an urgent upgrade.

The new supercomputer will ensure NCI can continue to provide essential support for research funded and sustained by the national research councils (the Australian Research Council and the National Health and Medical Research Council), and the national science agencies—notably CSIRO, the Bureau of Meteorology and Geoscience Australia.

This research will drive innovation that is critical to Australia’s future economic development and the wellbeing of Australians.

Carnegie Mellon Reveals Inner Workings of Victorious AI

HPC Wire - Mon, 12/18/2017 - 10:15

PITTSBURGH, Pa., Dec. 18, 2017 — Libratus, an artificial intelligence that defeated four top professional poker players in no-limit Texas Hold’em earlier this year, uses a three-pronged approach to master a game with more decision points than atoms in the universe, researchers at Carnegie Mellon University report.

In a paper published online Sunday by the journal Science, Tuomas Sandholm, professor of computer science, and Noam Brown, a Ph.D. student in the Computer Science Department, detail how their AI was able to achieve superhuman performance by breaking the game into computationally manageable parts. They also explain how, based on its opponents’ game play, Libratus fixed potential weaknesses in its strategy during the competition.

AI programs have defeated top humans in checkers, chess and Go — all challenging games, but ones in which both players know the exact state of the game at all times. Poker players, by contrast, contend with hidden information — what cards their opponents hold and whether an opponent is bluffing.

In a 20-day competition involving 120,000 hands at Rivers Casino in Pittsburgh during January 2017, Libratus became the first AI to defeat top human players at head’s up no-limit Texas Hold’em — the primary benchmark and long-standing challenge problem for imperfect-information game-solving by AIs.

Libratus beat each of the players individually in the two-player game and collectively amassed more than $1.8 million in chips. Measured in milli-big blinds per hand (mbb/hand), a standard used by imperfect-information game AI researchers, Libratus decisively defeated the humans by 147 mmb/hand. In poker lingo, this is 14.7 big blinds per game

“The techniques in Libratus do not use expert domain knowledge or human data and are not specific to poker,” Sandholm and Brown said in the paper. “Thus they apply to a host of imperfect-information games.” Such hidden information is ubiquitous in real-world strategic interactions, they noted, including business negotiation, cybersecurity, finance, strategic pricing and military applications.

Libratus includes three main modules, the first of which computes an abstraction of the game that is smaller and easier to solve than by considering all 10161 (the number 1 followed by 161 zeroes) possible decision points in the game. It then creates its own detailed strategy for the early rounds of Texas Hold’em and a coarse strategy for the later rounds. This strategy is called the blueprint strategy.

One example of these abstractions in poker is grouping similar hands together and treating them identically.

“Intuitively, there is little difference between a King-high flush and a Queen-high flush,” Brown said. “Treating those hands as identical reduces the complexity of the game and thus makes it computationally easier.” In the same vein, similar bet sizes also can be grouped together.

But in the final rounds of the game, a second module constructs a new, finer-grained abstraction based on the state of play. It also computes a strategy for this subgame in real-time that balances strategies across different subgames using the blueprint strategy for guidance — something that needs to be done to achieve safe subgame solving. During the January competition, Libratus performed this computation using the Pittsburgh Supercomputing Center’s Bridges computer.

Whenever an opponent makes a move that is not in the abstraction, the module computes a solution to this subgame that includes the opponent’s move. Sandholm and Brown call this nested subgame solving.

DeepStack, an AI created by the University of Alberta to play heads-up, no-limit Texas Hold’em, also includes a similar algorithm, called continual re-solving; DeepStack has yet to be tested against top professional players, however.

The third module is designed to improve the blueprint strategy as competition proceeds. Typically, Sandholm said, AIs use machine learning to find mistakes in the opponent’s strategy and exploit them. But that also opens the AI to exploitation if the opponent shifts strategy.

Instead, Libratus’ self-improver module analyzes opponents’ bet sizes to detect potential holes in Libratus’ blueprint strategy. Libratus then adds these missing decision branches, computes strategies for them, and adds them to the blueprint.

In addition to beating the human pros, Libratus was evaluated against the best prior poker AIs. These included Baby Tartanian8, a bot developed by Sandholm and Brown that won the 2016 Annual Computer Poker Competition held in conjunction with the Association for the Advancement of Artificial Intelligence Annual Conference.

Whereas Baby Tartanian8 beat the next two strongest AIs in the competition by 12 (plus/minus 10) mbb/hand and 24 (plus/minus 20) mbb/hand, Libratus bested Baby Tartanian8 by 63 (plus/minus 28) mbb/hand. DeepStack has not been tested against other AIs, the authors noted.

“The techniques that we developed are largely domain independent and can thus be applied to other strategic imperfect-information interactions, including non-recreational applications,” Sandholm and Brown concluded. “Due to the ubiquity of hidden information in real-world strategic interactions, we believe the paradigm introduced in Libratus will be critical to the future growth and widespread application of AI.”

The technology has been exclusively licensed to Strategic Machine, Inc., a company founded by Sandholm to apply strategic reasoning technologies to many different applications.

A paper by Brown and Sandholm regarding nested subgame solving recently won a Best Paper award at the Neural Information Processing Systems (NIPS 2017) conference. Libratus received the HPCwire Reader’s Choice Award for Best Use of AI at the 2017 International Conference for High Performance Computing, Networking, Storage and Analysis (SC17).

World Record: Quantum Computer with 46 Qubits Simulated

HPC Wire - Mon, 12/18/2017 - 10:04

Researchers from Jülich Supercomputing Centre, Wuhan University, and the University of Groningen, reported last week they successfully simulated a quantum computer with 46 quantum bits (qubits) for the first time. The researchers used the Jülich supercomputer JUQUEEN as well as the world’s fastest supercomputer Sunway TaihuLight at China’s National Supercomputing Center in Wuxi. Simulations such as this are critical for development of quantum programming expertise and software tools.

“There are only a few supercomputers in the world that currently have such a large amount of memory, an adequate number of compute nodes, and sufficiently fast network connections to even simulate a system of 45 qubits – that was the former world record,” explains Kristel Michielsen from the Jülich Supercomputing Centre (JSC). “And it’s just as important to get software up and running efficiently on the highly parallel architectures of state-of-the-art supercomputers.” A brief account of the work is posted on the Jülich web site.

Implementing quantum computing software and algorithms on classical systems is an ongoing challenge. Many codes lose efficiency if calculated in parallel on a large number of compute nodes. However, the software which Michielsen has been developing together with her partners for over ten years scales almost perfectly according to the report: “It shows hardly any loss in performance even if several million compute nodes are applied at the same time, as is the case with the Chinese supercomputer Sunway TaihuLight.”

Michielsen has already set a number of benchmarks in the past. In 2010, she became the first person to simulate a quantum computer with 42 qubits on the former Jülich supercomputer JUGENE. She then surpassed that world record in 2012 with the simulation of a 43-qubit system on JUQUEEN, the successor to JUGENE. Most recently, Michielsen simulated a 45-qubit quantum system together with partners from universities in Groningen, Tokyo, and Wuhan, thus equalling a record set in spring 2017. For that more than 500,000 gigabytes, or 0.5 petabytes, of memory were needed.

The latest breakthrough, which involved the simulation of a quantum computer with 46 qubits, was achieved following an adjustment of the simulation code. The representation of a quantum state now only requires 2 bytes instead of 16 bytes, without the accuracy of the results being significantly reduced. Other users can benefit from this simplification, which equates to a reduction in required memory by a factor of eight. The new version of the simulation software now enables a quantum computer with 32 qubits to be simulated on a notebook with 16 gigabytes of memory.

Researchers Advance User-Level Container Solution for HPC

HPC Wire - Mon, 12/18/2017 - 09:51

Most scientific computing facilities, such us HPC or grid infrastructures, are shared among different research disciplines, and thus the system software environment needs to be generic enough to accommodate different user and applications profiles; they are multi-user environments.

Because of managerial and technical constraints, such infrastructures cannot afford offering every research project a tailored environment in their machines. Therefore the interest of exploring the applicability of containers technology on such systems is rather evident from the end-user point of view.

Researchers need then to customize their applications software to fit the computing center environment at the level of system software and batch system. Containers provide a way to pack and deploy software including all the dependencies in a way that can be executed in a seamless way, independently of the underlying Linux Operating System and environment. The main benefit of integrating the execution of containers in HPC systems would then be to provide a way to execute applications homogeneously across different resource centers.

The flagship container software, Docker, cannot be used in a satisfactory way on HPC systems, grids and in general multi-user oriented infrastructures. Deploying Docker on such facilities presents a number of problems related to the fact that within the container, processes are executed with the root id. This raises security concerns among system managers, as the Docker root might be able to gain access to root privileges in the host machine. Also, when executed as root, the processes escape from the usual managerial limits on resource consumption or accounting, imposed on regular users at shared facilities.

User-level tools

The user-level tool udocker provides a layer for users to execute Docker containers, that by definition, does not require the intervention of the system administrators. Udocker combines the pulling, extraction and execution of Docker containers without requiring privileges. The Docker image is extracted on a user-space filesystem area, and from there on, it is executed in an chroot-like environment.

udocker provides a command line interface that mimics Docker, providing a subset of its commands to be able to handle Docker images at the level of pulling, extracting and execute containers “á la Docker”.

Processes are run without privileges under the regular user id, under the same process tree, thus facilitating the enforcement of the managerial limits imposed to regular users in HPC or grid resource centers.

udocker provides several ways, depending on the application and host environment, to execute containerized applications. It is also possible to access specialized hardware like Infiniband for MPI jobs, or GPGPUs, making it adequate to execute containers in batch systems and HPC infrastructures.

udocker enables the execution of Docker containers with different engines based on intercepting system calls. Depending on the application requirements the user may choose to run in one execution mode or another. For instance CPU-intensive applications may use udocker in the ptrace execution mode, to intercept and modify pathnames; if the application is I/O intensive the interception of system calls via library pre-loading using the Fakechroot execution mode is a more adequate way to run the container. All the tools and libraries required by udocker and its execution modes are provided with udocker itself.

The udocker execution mode RunC employs the technology of user namespaces to run the containers in rootless mode. This feature can be used with modern Linux distributions with kernels from 3.9 on. However most HPC systems are conservative environments and it will take some time until they will be able to support this execution mode.

Regarding impact in performance, in the figure presented below we have plotted the weak scaling performance of openQCD, a comprehensive software package to run Lattice QCD simulations (a CPU-intensive application) from 8 to 256 cores.

As we see, the performance of the containerized version of openQCD is slightly higher than the one on the host itself. This is especially so when the execution takes place within a single node (the test machine has 24-core nodes).

This behavior has been reported consistently by container users across different hardware and system software settings, and it is related to the better libraries available in the more advanced versions of the operating systems inside the container. Clearly this feature opens the door to container exploitation in HPC mainframes since there the software system is by necessity very conservative.

Figure Caption: Weak Scaling performance of openQCD with a local lattice of Volume=32^4. The tests have been performed on the Finisterrae-II HPC system at CESGA (Spain).

Since its first release in June 2016 udocker expanded quickly in the open source community. It is being used in large international collaborations like the case of MasterCode, a leading particle physics phenomenology collaboration, which uses udocker to handle the library complexity of the set of codes included in the MasterCode.

It has also been adopted by a number of software projects to complement Docker. Among them openmole, bioconda, Common Workflow Language or SCAR.

System Administration level

Beyond the user level, several solutions have been developed in recent times to support system administrators in deploying customized containers for their users. These solutions rely on the installation of system software by the system administrator, which also is in charge of preparing the containers that the users are authorized to run on the system. The most popular of these tools is Singularity.

Singularity can be downloaded and installed from source or binaries, and must be installed by root for the software to have all the functionalities. Singularity binaries are therefore installed with SUID and need be deployed in a filesystem that allows SUID. Given the security concerns on network filesystems regarding SUID, Singularity is normally installed in a directory locally accessible to the users (i.e., not network-mounted).

Singularity offers its own containers registry, the Singularity Hub, and its own specification to create containers, the Singularity Recipe (i.e., the Singularity equivalent of the Dockerfile specification).

The default container format is squashfs, which is a compressed read-only Linux file system, where the images need to be created by root.

It also supports a sandbox format, in which the container is deployed inside a standard Unix directory, much like udocker. In particular, executing udocker in Singularity execution mode will cause the container to be executed via Singularity if installed in the system. In order to do this udocker exploits the sandbox mode.

The container building environment of Singularity belongs to root. Containers may be built either from a Singularity recipe, from a previous container coming from the Singularity Hub, or importing a container from the Docker repository. Notice that the Singularity format for containers is not compatible with Docker; therefore, in the latter case the container needs to be converted to the Singularity format.

Once the container exists, it can be executed by a regular user in a way analogous to Docker. These containers can also be checked at the binary level, at the level of sensitive content of the filesystem for example, or even for particular features defined by the system administrator.

The comparison of the most popular tools, udocker and Singularity, shows that they have a completely different scope, and the selection of one solution or another depends on the priorities at the user level and the computing center management policies.

Singularity is a system administration level tool, to be installed at this level, giving the managers of the infrastructure full control of which containers are run into the system or not. Udocker however is a user tool that acts as a layer over different execution methods, enabling regular users to run containers in their own user space, much in the philosophy of the jailed systems.

Leveraging Singularity to Unleash the Power of Hybrid HPC Clouds

HPC Wire - Mon, 12/18/2017 - 01:01

Today’s HPC centers demand the flexibility of hybrid computing environments.  CFOs and CIOs understand the potential cost benefits of cloud computing and do not wish to be limited by on-premise compute investments.  A challenge administrators face when extending their computing capacity outside of their datacenter is delivering a cloud resource in a way that is easy for users to adopt. They need a straightforward extension of computing power into on-demand cloud services

HPC users have a myriad of operating system and application choices available to them in the open source community. Whether due to personal preference or scientific need, it is impossible to fit all application workflows into a single bucket.  This requires that HPC centers provide users with the tools needed to build custom application stacks in their environment of choice.

While virtualization technologies provide the capability to compartmentalize software into portable virtual machines, HPC applications face unacceptable performance and scalability limitations when running in a virtual environment.

The rise of Linux containers and the rapid success of frameworks like Docker quickly became of interest to the HPC community as containers enable the encapsulation of custom applications and their runtime environments without the performance penalty of virtualization.  Containers gave hope for the long awaited, bare-metal answer to software portability which could streamline the adaptability of hybrid cloud computing. HPC administrators quickly realized that although Linux containers could facilitate hybrid computing models, the available tools were designed for enterprise microservices and could not be easily, or securely be integrated into HPC clusters.

Singularity, founded by Gregory M. Kurtzer and supported by Lawrence Berkeley National Lab was launched in April of 2016 as the definitive framework for HPC Linux containers.  The Singularity team addressed all of the HPC challenges presented by enterprise container solutions including native support for MPI, a single flat-file image for hosting containers on parallel filesystems, restricted privilege escalation inside the container for security, and a user-space execution architecture that allowed HPC schedulers to retain control of resource management and job scheduling.

Additionally, Singularity is compatible with popular container repositories such as DockerHub.  This provides users the option to leverage the growing public depots of pre-packaged, containerized applications.  With two commands, a user can create a ready to run Singularity container from a Docker registry.

“I spoke with numerous scientists, and the problem to solve became clear. We need to support application mobility via an easily verifiable reproducible software stack that the scientists control and a runtime that fits a usage paradigm that fits a traditional HPC system architecture. This was the birth of the Singularity project.”  — Gregory M. Kurtzer.

Penguin Computing is a leader in open computing solutions, and delivers various hybrid computing options through Penguin Computing On-Demand (POD), a bare-metal HPC cloud service.  Coupled with Singularity, POD users are able to compartmentalize their software, and migrate workloads to and from the cloud without any changes to their operating system or application binaries.  Their HPC application stack is consistent and reproducible whether on-premise or in the cloud, and is not restrained by the underlying operating system HPC administrators choose to provision their clusters.

Administrators are able to drop-in Singularity to their on-premise clusters without any changes to their provisioning or scheduling environment.  The simple installation of Singularity encourages and empowers users to adopt the hybrid computing options their organization wishes to embrace. An HPC cluster can easily be enabled to allow users to create Linux containers that extend into POD for seamless integration into the cloud.

Penguin Computing’s POD is proud to be part of the community of HPC centers embracing Singularity, such as the National Institute of Health, the Texas Advanced Computing Center, and Lawrence Berkeley National Lab.

“The new C/C++ and Fortran compilers provide full exploitation of POWER9 technology for industry-leading performance and optimize HPC and Cognitive workloads through GPU acceleration, and is ideal for HPC clients, scientists, and AI leads,” says IBM. 

The POWER9 exploitation features, including a number of new POWER9 built-in functions and high-performance libraries tuned for POWER9, allow the development of optimized applications that utilize the latest POWER9 technology.

The IBM XL compilers’ support for OpenMP 4.5 is enhanced in this new release – new SIMD directives are added and functionality for existing directives is expanded to provide further exploitation and effective programming on GPU.

CUDA Fortran support is also improved to provide better performance for kernels, more functions and customized GPU configurations.

“With the best overall optimization for both CPU & GPU, XL Compilers are positioned as the performance-driven compiler brand on Power Systems to unlock HPC & Cognitive workloads. XL compilers are the ultimate choice to solve massive, complex computing tasks,” said the offering manager of IBM XL compilers.

Other key features of XL C/C++ for Linux V13.1.6 and XL Fortran for Linux V15.1.6 include:

  • Adoption of Clang V4.0 frond-end technology – XL C/C++ for Linux adopts Clang V4.0 frond-end technology, which provides a large degree of compatibility with GCC. Migration to XL C/C++ for Linux is now easy and seamless. More C++14 language features are supported, such as binary integer literals, digit separators, relaxing constraints on constexpr functions, return type deduction for normal functions, etc.
  • OpenMP interoperability with CUDA C/C++ and CUDA Fortran – Development of more portable applications is enabled by calling kernels written in CUDA C/C++ or CUDA Fortran in OpenMP programs from the host.
  • Support for CUDA Toolkit 9.0 and 9.1 – Support for the CUDA Toolkit has been upgraded to CUDA Toolkit version 9.0 and 9.1. The sm_70 and compute_70 GPU architectures are supported as defined by the CUDA Toolkit.
  • Specification of GPU architectures for the generated code – The new -qtgtarch option allows specifying the real or virtual GPU architectures where the code can run, overriding the default GPU architecture. The compiler can take maximum advantage of the capabilities and machine instructions which are specific to a GPU architecture, or common to a virtual architecture.
  • Support for the cuda-memcheck tool – A new environment variable is provided to control whether to disable the check for pinned memory in the runtime and allow the program to be executed under the cuda-memcheck tool from the NVIDIA CUDA Toolkit.
  • Pass LLVM IR bitcode libraries to llvm2ptx – LLVM IR bitcode libraries, which have a suffix of .bc, can be specified on the command line, to pass the LLVM IR bitcode libraries to llvm2ptx, the NVVM-IR to PTX translator.
  • GPU runtime inlining support for inlining calls made to the OpenMP GPU runtime libraries – This enhancement reduces overhead and significantly improves performance of OpenMP target regions that are offloaded to the accelerator.

BP Supercomputer Now World’s Most Powerful for Commercial Research

HPC Wire - Fri, 12/15/2017 - 09:49

HOUSTON, Dec. 15, 2017 — BP announced today that it has more than doubled the total computing power of its Center for High-Performance Computing (CHPC) in Houston, making it the most powerful supercomputer in the world for commercial research.

Increased computing power, speed and storage reduce the time needed to analyze large amounts of seismic data to support exploration, appraisal and development plans as well as other research and technology developments throughout BP.

“Our investment in supercomputing is another example of BP leading the way in digital technologies that deliver improved safety, reliability and efficiency across our operations and give us a clear competitive advantage,” said Ahmed Hashmi, BP’s head of upstream technology.

The Center for High-Performance Computing provides critical support to BP’s upstream business segment, where it serves as the worldwide hub for research computing. BP’s computer scientists and mathematicians at the CHPC have enabled industry breakthroughs in advanced seismic imaging and rock physics research to help with reservoir modelling.

BP’s downstream business also is using the supercomputer for fluid dynamic research to study hydrocarbon flows at refineries and pipelines to improve operational safety.

Working with Hewlett Packard Enterprise and Intel using HPE’s Apollo System and Intel’s Knights Landing processors, the recent upgrade has boosted the processing speed of BP’s supercomputer from four petaflops to nine petaflops. A petaflop of processing speed is one thousand trillion floating point operations, or “flops,” per second.

The supercomputer has a total memory of 1,140 terabytes (1.14 petabytes) and 30 petabytes of storage, the equivalent of over 500,000 iPhones.

“With the expansion and new systems in place, BP will be able to further bolster its capabilities to accurately process and manage vast amounts of seismic data to identify new business opportunities and improve operational efficiency,” said Alain Andreoli, senior vice president and general manager, Data Center Infrastructure Group, Hewlett Packard Enterprise.

Since the CHPC opened in 2013, BP has quadrupled its computing power and doubled its storage capacity and plans to continue expanding its computing capability in 2018.

The Mont-Blanc 2020 project intends to pave the way to the future low-power European processor for Exascale. To improve the economic sustainability of the processor generations that will result from the Mont-Blanc 2020 effort, the project includes the analysis of the requirements of other markets. The project’s strategy based on modular packaging would make it possible to create a family of SoCs
targeting different markets, such as “embedded HPC” for autonomous driving. The project’s actual objectives are to:

  • define a low-power System-on-Chip architecture targeting Exascale;
  • implement new critical building blocks (IPs) and provide a blueprint for its first generation implementation;
  • deliver initial proof-of-concept demonstration of its critical components on real life applications;
  • explore the reuse of the building blocks to serve other markets than HPC, with methodologies enabling a better time-predictability, especially for mixed-critical applications where guaranteed execution & response times are crucial.

The project will have to tackle three key challenges to achieve the desired performance with the targeted power consumption:

  1. understand the trade-offs between vector length, NoC bandwidth and memory bandwidth to maximize processing unit efficiency;
  2. an innovative on-die interconnect that can deliver enough bandwidth to the processing units, with minimum energy consumption;
  3. a high-bandwidth and low power memory solution with enough capacity and bandwidth for Exascale applications.

“The ambition of the consortium is to quickly industrialize our research. This is why we decided to rely on the Arm instruction set architecture (ISA), which is backed by a strong software ecosystem. By leveraging the current efforts, including the Mont-Blanc ecosystem and other international projects, we will benefit from the system software and applications required for successful usage” explained Said Derradji, Atos, coordinator of the Mont-Blanc 2020 project.

About the Mont-Blanc 2020 project

Mont-Blanc 2020’s goal is to initiate a family of processors that will be the basis for European Big Data / High Performance Computing exascale systems, and that will achieve market adoption and economic sustainability.

The Mont-Blanc 2020 project is run by a European consortium that includes:
Atos / Bull, the European number one in Big Data and High Performance Computing (coordinator, France);

  • Arm, the world’s leading semiconductor IP company (United Kingdom);
  • Barcelona Supercomputing Centre, the national supercomputing centre in Spain;
  • CEA, the French Alternative Energies and Atomic Energy Commission;
  • Forschungszentrum Jülich, one of the largest interdisciplinary research institutions in Europe (Germany);
  • Kalray, a leading innovator with its supercomputing on a chip MPPA solutions (France);
  • SemiDynamics, a specialist in microprocessor architecture, front-end design and verification services (Spain).

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 779877.

Cornerstone Design projects propose novel ways to upcycle

Colorado School of Mines - Thu, 12/14/2017 - 16:18

A durable, easy-to-install roofing shingle made from waste ceramics and grocery store plastic bags was the top project at the Fall 2017 Cornerstone Design Final Competition on Dec. 6.

A total of 24 student teams from Intro to Design (EPIC 151) exhibited their design solutions for reducing waste through upcycling at the final competition, representing the top team from each class section. 

The Engineers of the Round Table’s roofing shingle won first place in the Best Design Process category. Their shingle-making device utilizes a heating element to melt the plastic bags together and adhere the crushed ceramics to one side of the shingle, with a press and second plate ensuring uniform thickness. Team members were Justin Rozendaal, Ernest Smith, Anais Rostad, Jordan Vickers and Joseph Protiva.

Earning second place was Tr# Upcycle, for their machine to melt waste plastic into bricks for building houses. Team members were Charles Collins, Torin Hopkins-Arnold, Zack Hart, Connor Smith and Caleb Kotter.

The award for the Most Potentially Viable project went to Enginerds, for their modular phone charger assembled from the functional batteries in discarded cell phones. Forming the team were Kellen Parker, Landon Walker, Paxton Heiting and Nick Gonzales.

Required for all Mines undergraduates, EPIC 151 is a semester-long design course whose centerpiece is an open-ended design problem that students must solve as part of a team effort. 

This semester’s task was reducing the amount of material that enters the waste stream by designing novel, useful solutions – and the tools required to make those solutions – from items that would otherwise be thrown away. Solutions were required to fulfill a need felt by a significant number of people, while also making a meaningful impact on the waste stream, the environment and/or the community.

Mines president on team that wins ESTCP Project of the Year

Colorado School of Mines - Thu, 12/14/2017 - 10:37

Colorado School of Mines President Paul C. Johnson was part of a team of researchers recently honored for the top environmental restoration project of the year by the U.S. Department of Defense’s environmental technology demonstration and validation program.

The Environmental Security Technology Certification Program (ESTCP) announced its annual awards at the 2017 SERDP-ESTCP Symposium Nov. 28-30 in Washington D.C.

The project Johnson contributed to, “1,4-Dioxane Remediation by Extreme Soil Vapor Extraction (XSVE),” led by Rob Hinchee from Integrated Science & Technology Inc. (IST), was honored for developing a novel cost-effective way to remove 1,4-Dioxane from soils. 1,4-Dioxane is a possible cancer-causing chemical that can contaminate and persist in groundwater, and is found at chlorinated solvent spill sites and in some household products. 

“This project was a great example of the accelerated technology transfer that DoD hopes to see in the ESTCP program,” Johnson said. “Within only a few years, the XSVE technology went from concept to validation, and now environmental engineers have a new easy-to-apply option for restoring 1,4-Dioxane-contaminated sites.”

The team successfully demonstrated the XSVE technology at a field site and developed a design tool, HypeVent XSVE, that others can use to simulate the remediation of 1,4-Dioxane under a range of XSVE design conditions. Study results showed 1,4-dioxane concentrations in the treatment area decreasing about 95 percent, in good agreement with the projected results.

In addition to Johnson, team members included Hinchee and Dave Burris of IST, Paul Dahlen and Yuanming Guo of Arizona State University, Kimiye Touchi of AECOM, Hunter Anderson of AFCEC and Dave Becker of USACE. This is the third project-of-the-year award that Johnson has received from the SERDP-ESTCP programs.

A chemical engineer by training, Johnson holds a bachelor’s degree from University of California–Davis and master’s and doctoral degrees from Princeton University.

Established in 1995, ESTCP’s goal is to identify and demonstrate the most promising, innovative and cost-effective technologies to address DoD’s high-priority environmental requirements. Projects are managed within five areas – energy and water, environmental restoration, munitions response, resource conservation and resiliency, and weapons systems and platforms.

Twelve organizations in total will be using the IBM prototype quantum computer via the company’s cloud service to accelerate quantum development as they explore a broad set of industrial and scientific applications. Other partners include JSR Corporation, Barclays, Hitachi Metals, Honda, and Nagase.

Partners currently have access to the 20 qubit IBM Q system, which IBM announced last month, but Big Blue is also building an operational prototype 50 qubit processor, which will be made available in next generation IBM Q systems. The partners will specifically be looking to identify applications that will elicit a quantum advantage, such that they perform better or faster on a quantum machine than a classical one.

IBM leadership believes we are at the dawn of the commercial quantum era. “The IBM Q Network will serve as a vehicle to make quantum computing more accessible to businesses and organizations through access to the most advanced IBM Q systems and quantum ecosystem,” said Dario Gil, vice president of AI and IBM Q, IBM Research in a statement. “Working closely with our clients, together we can begin to explore the ways big and small quantum computing can address previously unsolvable problems applicable to industries such as financial services, automotive or chemistry. There will be a shared focus on discovering areas of quantum advantage that may lead to commercial, intellectual and societal benefit in the future.”

Experts from the newly formed IBM Q Consulting will be able to provide support and offer customized roadmaps to help clients become quantum-ready, says IBM.

With IBM Q, IBM seeks to be the first tech company to deliver commercial universal quantum computing systems for and in tandem with industry and research users. Although today marks the start of its commercial network, IBM has been providing scientists, researchers, and developers with free access to IBM Q processors since May 2016 via the IBM Q Experience. According to the company, 60,000 registered users have collectively run more than 1.7 million experiments and generated over 35 third-party research publications.

Lenovo and Intel to Deliver Next-Generation Supercomputer to Leibniz Supercomputing Center

HPC Wire - Thu, 12/14/2017 - 09:21

RESEARCH TRIANGLE PARK, N.C., Dec. 14, 2017 — Lenovo (SEHK:0992) (Pink Sheets:LNVGY) Data Center Group and Intel will deliver a next-generation supercomputer to Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences in Munich, Germany. One of the foremost European computing centers for professionals in the scientific, research and academic communities, LRZ is tasked with managing not only exponential amounts of big data, but processing and analyzing that data quickly to accelerate research initiatives around the world. For example, the LRZ recently completed the world’s largest simulation of earthquakes and resulting tsunami’s, such as the Sumatra-Andaman Earthquake. This research enables real-time scenarios planning that can help predict aftershocks and other seismic hazards.

Upon its completion in late 2018, the new supercomputer (called SuperMUC-NG) will support LRZ in its groundbreaking research across a variety of complex scientific disciplines, such as astrophysics, fluid dynamics and life sciences, by offering highly available, secure and energy-efficient high-performance computing (HPC) services that leverage industry-leading technology optimized to address the a broad range of scientific computing applications. The LRZ installation will also feature the 20-millionth server shipped by Lenovo, a significant milestone in the company’s data center history.

“Lenovo is committed to providing research institutions like LRZ with not only sheer computing power, but a true, end-to-end solution that can help effectively and efficiently solve critical humanitarian challenges. We’re pleased to be working on this next-generation project in partnership with Intel,” said Scott Tease, Executive Director, HPC and AI, Lenovo Data Center Group. “The new SuperMUC-NG installation will provide LRZ with greater compute power in a smaller data center footprint with drastically reduced energy usage through innovative water-cooling technology, offering researchers a comprehensive supercomputing solution that packs more performance than ever to accelerate critical research projects.”

The SuperMUC-NG will deliver a staggering 26.7 petaflop compute capacity powered by nearly 6,500 nodes of Lenovo’s recently-announced, next-generation ThinkSystem SD650 servers, featuring Intel Xeon Platinum processors with Intel Advanced Vector Extensions (Intel AVX 512), and interconnected with Intel Omni-Path Architecture. The new system will also include the integration of Lenovo Intelligent Computing Orchestrator (LiCO), a powerful management suite with an intuitive GUI that helps accelerate development of HPC and AI applications, as well as cloud-based components to empower LRZ researchers with the freedom to virtualize, process the vast amount of data sets and expediently share results with colleagues.

To address the often-astronomical operational expenses generated by high-performance computing (HPC) infrastructure, the new SuperMUC-NG supercomputer will benefit from Intel technical optimizations and also feature cutting-edge water cooling technology from Lenovo. In combination with Lenovo Energy Aware Run-Time (EAR) software, a technology that dynamically controls system infrastructure power while applications are still running, Lenovo’s comprehensive water-cooling technology delivers 45 percent greater electricity savings to LRZ as compared to a similar, standard air-cooled system. Together, these energy efficiency innovations will help further reduce the research center’s carbon footprint and total cost of ownership.

“Global research leaders like LRZ are driving insights that address not only some of the most complex problems we face, but that also make meaningful improvements in all of our lives,” said Trish Damkroger, Vice President of Technical Computing at Intel. “Intel offers the technical foundation that, when combined with the solution expertise of Lenovo, delivers the efficient performance and ease of programing to help LRZ’s researchers drive more discoveries with deeper analytics than have ever been possible before.”

Once operational, the LRZ SuperMUC-NG system is expected to place on the industry-wide TOP500 list.

Second Industry-Wide, Multi-Vendor Plugfest Focused on NVMe Over Fibre Channel Fabric Completed by Fibre Channel Industry Association

HPC Wire - Wed, 12/13/2017 - 13:48

MINNEAPOLIS, Dec. 13, 2017 — The Fibre Channel Industry Association (FCIA) today announced the completion of its second industry-wide multi-vendor plugfest focused on Non-Volatile Memory Express  (NVMe) over Fibre Channel (FC) Fabric and the first validation of the newly completed INCITS T11 FC-NVMe standard.

FCIA’s FC-NVMe plugfest was held during the NVM Express organization’s management interface (NVMe-MI) plugfest, the week of October 30, 2017, at the University of New Hampshire InterOperability Lab (UNH-IOL).  An independent provider of broad-based testing and standards conformance services for the networking industry, UNH-IOL has conducted more than 38 plugfests with FCIA over 18 years to test the continued development of FC technologies.

“The completion of this second FC-NVMe plugfest comes at a critical junction,” said FC-NVMe plugfest participant Mark Jones, president and chairman of the board, FCIA, and director, Technical Marketing and Performance, Broadcom Limited. “Major operating system vendors are just releasing support for NVMe over Fabrics and the FC-NVMe INCITS T11 standard is now complete and has been forwarded to INCITS. The FC-NVMe technology is on track to becoming as interoperable and reliable as previous generations of FC, while vastly improving performance for the next generation all-flash datacenters.”

With nine companies participating, the FCIA’s FC-NVMe plugfest featured conformance, error injection, multi-hop, and interoperability testing of FC-NVMe concurrently with Gen 6 32GFC and previous FC generation fabric switches and directors, utilizing datacenter-proven test tools and test methods.

Key accomplishments from this second FCIA-sponsored plugfest of FC-NVMe include:

  • Multiple vendor FC-NVMe initiator, switch, and target conformance and interoperability
  • Gen 6 16 and 32GFC fabric connectivity to a variety of market available NVMe drives
  • Data integrity validation over multi-vendor direct-connect and switched multi-hop fabric topologies
  • Error injection tests to validate correct FC-NVMe and FC recovery and data integrity
  • Concurrent NVMe and legacy SCSI traffic through the same FC fabric ports
  • FC-NVMe and FC over 32GFC long wave 10km single mode fiber inter-switch trunked ports
  • FC-NVMe packet inspection conformance analysis using advanced trace capture and analysis tools
  • Cross fabric inline trace based relative performance comparisons of FCP-SCSI and FC-NVMe
  • Multi-vendor high availability multi-speed concurrent FC-NVMe and FC fabric conformance and interoperability
  • Trials of the UNH-IOL’s NVMe over Fabrics conformance test suite of products for inclusion on the NVMe Integrator’s List

“It is an honor to lead and participate in plugfests with outstanding engineers from across the FC industry who share a single purpose of driving FC-NVMe technology to be interoperable at the highest level of dependability expected by the FC community,” said Barry Maskas, plugfest chair and Technical Staff consultant at Hewlett Packard Enterprise. “In comparison to the first FC-NVMe focused plugfest, results from this second event showed continued maturation demonstrated through tested use case configurations. Plugfest participants refined the validation, certification, and performance characterization foundation which has proven successful by previous FC technology innovations for the benefit of our collective customers.”The nine companies participating in FCIA’s FV-NVMe plugfest were:

  • Amphenol Corporation
  • Brocade Communications Systems, Inc.
  • Broadcom Limited
  • Cisco Systems
  • Hewlett Packard Enterprise
  • QLogic Corporation, a Cavium, Inc. company
  • SANBlaze Technology, Inc.
  • Teledyne Technologies; LeCroy Corporation
  • Viavi Solutions Inc.

“The UNH-IOL has worked with the FCIA and its member companies for over 20 years on Fibre Channel’s latest technological enhancements,” said Timothy Sheehan, manager, Datacenter Technologies, UNH-IOL. “The IOL is focused on supporting the for Non-Volatile Memory Express (NVMe) Fabrics conformance and interoperability testing and has brought this experience to the FCIA member companies. The last two FCIA plugfest events have focused on FC-NVMe testing and have shown great progress.”

NVM Express, Inc. Debuts NVMe Over Fabrics Compliance Testing

HPC Wire - Wed, 12/13/2017 - 12:58

BEAVERTON, Ore., Dec. 13, 2017—NVM Express, Inc., the organization that developed the NVM Express (NVMe) and NVMe Management Interface (NVMe-MI) specifications for accessing solid-state drives (SSDs) on a PCI Express (PCIe) bus as well as over Fabrics, hosted its eighth NVMe Plugfest at theUniversity of New Hampshire Interoperability Laboratory (UNH-IOL) in Durham, N.H. during the week of October 30—November 2. The event offered the first official NVMe Over Fabrics (NVMe-oF) compliance and interoperability transport layer testing for RoCE, Remote Direct Memory Access (RDMA) over Converged Ethernet, and the Fibre Channel.

The testing performed by the UNH-IOL, an independent testing provider of standards conformance solutions and multi-vendor interoperability, generated 14 new certified products for the base NVMe Integrators Listand one for the NVMe-MI Integrators List. Eight inaugural products were also approved for the newly launched NVMe-oF Integrators List, which accepts RoCE initiators and targets, Ethernet switches, as well as Fibre Channel initiator, targets and switches, and software.

“Since 2013, the UNH-IOL has certified over 112 NVMe-based products at the NVM Express Plugfests,” David Woolf, senior engineer, Datacenter Technologies at the UNH-IOL, said. “By continuing to prioritize specification compliance and interoperability testing, companies can ensure faster time to market and seamless interactions with other devices NVMe-based solutions.”
