Physicists Win Supercomputing Time to Study Fusion and the Cosmos

Tue, 12/12/2017 - 13:10

Dec. 12, 2017 — More than 210 million core hours on two of the most powerful supercomputers in the nation have been won by two teams led by researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). The highly competitive awards from the DOE Office of Science’s INCITE (Innovative and Novel Impact on Computational Theory and Experiment) program will accelerate the development of nuclear fusion as a clean and abundant source of energy for generating electricity and will advance understanding of the high-energy-density (HED) plasmas found in stars and other astrophysical objects.

A single core hour represents the use of one computer core, or processor, for one hour. A laptop computer with only one processor would take some 24,000 years to run 210 million core hours.

“Extremely important and beneficial”

“These awards are extremely important and beneficial,” said Michael Zarnstorff, deputy director for research at PPPL. “They give us access to leadership-class highest-performance computers for highly complex calculations. This is key for advancing our theoretical modeling and understanding.” Leadership-class computing systems are high-end computers that are among the most advanced in the world for solving scientific and engineering problems.

The allocations include more than 160 million core hours for physicist C.S. Chang and his team, marking the first year of a renewable three-year award. The first-year hours are distributed over two machines: 100-million core hours on Titan, the most powerful U.S supercomputer, which can perform some 27 quadrillion (1015) calculations per second at the Oak Ridge Leadership Computing Facility (OLCF); and 61.5 million core hours on Theta, which completes some 10 quadrillion calculations a second at the Argonne Leadership Computing Facility (ALCF).  Both sites are DOE Office of Science User Facilities.

Also received are 50 million core hours on Titan for Amitava Bhattacharjee, head of the Theory Department at PPPL, and William Fox and their team to study HED plasmas produced by lasers.

Chang’s group consists of colleagues at PPPL and other institutions and will use the time to run the XGC code developed by PPPL and nationwide partners.  The team is exploring the dazzlingly complex edge of fusion plasmas with Chang as lead principal investigator of the partnership center for High-fidelity Boundary Plasma Simulation — a program supported by the DOE Office of Science’s Scientific Discovery through Advanced Computing (SciDAC). The edge is critical to the performance of plasma that fuels fusion reactions.

Fusion — the fusing of light elements

Fusion is the fusing of light elements that most stars use to generate massive amounts of energy – and that scientists are trying to replicate on Earth for a virtually inexhaustible supply of energy. Plasma – the fourth state of matter that makes up nearly all the visible universe – is the fuel they would use to create fusion reactions.

The XGC code will perform double-duty to investigate developments at the edge of hot, charged fusion plasma. The program will simulate the transition from low- to high-confinement of the edge of fusion plasmas contained inside magnetic fields in doughnut-shaped fusion devices called tokamaks. Also simulated will be the width of the heat load that will strike the divertor, the component of the tokamak that will expel waste heat and particles from future fusion reactors based on magnetic confinement such as ITER, the international tokamak under construction in France to demonstrate the practicality of fusion power.

The simulations will build on knowledge that Chang has achieved in the previous-cycle SciDAC project.  “We’re just getting started,” Chang said. “In the new SciDAC project we need to understand the different types of transition that are thought to occur in the plasma, and the physics behind the width of the heat load, which can damage the divertor in future facilities such as ITER if the load is too narrow and concentrated.”

Advancing progress in understanding HED plasmas

The Bhattacharjee-Fox award, the second and final part of a two-year  project, will advance progress in the team’s understanding of the dynamics of magnetic fields in HED plasmas. “The simulations will be immensely beneficial in designing and understanding the results of experiments carried out at the University of Rochester and the National Ignition Facility at Lawrence Livermore National Laboratory” Bhattacharjee said.

The project explores the magnetic reconnection and shocks that occur in HED plasmas, producing enormous energy in processes such as solar flares, cosmic rays and geomagnetic storms. Magnetic reconnection takes place when the magnetic field lines in plasma converge and break apart, converting magnetic energy into explosive particle energy. Shocks appear when the flows in the plasma exceed the speed of sound, and are a powerful process for accelerating charged particles.

To study the process, the team fires high-power lasers at tiny spots of foil, creating plasma bubbles with magnetic fields that collide to form shocks and come together to create reconnection. “Our group has recently made important progress on the properties of shocks and novel mechanisms of magnetic reconnection in laser-driven HED plasmas,” Bhattacharjee said. “This could not be done without INCITE support.”

PPPL, on Princeton University’s Forrestal Campus in Plainsboro, N.J., is devoted to creating new knowledge about the physics of plasmas — ultra-hot, charged gases — and to developing practical solutions for the creation of fusion energy. The Laboratory is managed by the University for the U.S. Department of Energy’s Office of Science, which is the largest single supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time.

ESnet Now Moving More Than 1 Petabyte/wk

Tue, 12/12/2017 - 09:20

Optimizing ESnet (Energy Sciences Network), the world’s fastest network for science, is an ongoing process. Recently a two-year collaboration by ESnet users – the Petascale DTN Project – achieved its ambitious goal to deliver sustained data transfers at over the target rate of 1 petabyte per week. ESnet is managed by Lawrence Berkeley National Laboratory for the Department of Energy.

During the past two years ESnet engineers have been working with staff at DOE labs to fine tune the specially configured systems called data transfer nodes (DTNs) that move data in and out of the National Energy Research Scientific Computing Center (NERSC) at LBNL and the leadership computing facilities at Argonne National Laboratory and Oak Ridge National Laboratory. A good article describing the ESnet project (ESnet’s Petascale DTN project speeds up data transfers between leading HPC centers) was posted yesterday on Phys.org.

A variety of software and hardware upgrades and expansion were required to achieve the speedup. Here are two examples taken from the article:

  • At NERSC, the DTN project resulted in adding eight more nodes, tripling the number, in order achieve enough internal bandwidth to meet the project’s goals. “It’s a fairly complicated thing to do,” said Damian Hazen, head of NERSC’s Storage Systems Group. “It involves adding infrastructure and tuning as we connected our border routers to internal routers to the switches connected to the DTNs. Then we needed to install the software, get rid of some bugs and tune the entire system for optimal performance.”
  • Oak Ridge Leadership Computing Facility now has 28 transfer nodes in production on 40-Gigabit Ethernet. The nodes are deployed under a new model—a diskless boot—which makes it easy for OLCF staff to move resources around, reallocating as needed to respond to users’ needs. “The Petascale DTN project basically helped us increase the ‘horsepower under the hood’ of network services we provide and make them more resilient,” said Jason Anderson, an HPC UNIX/storage systems administrator at OLCF. “For example, we recently moved 12TB of science data from OLCF to NCSA in less than 30 minutes. That’s fast!”

The Petascale DTN collaboration also includes the National Center for Supercomputing Applications (NCSA) at the University of Illinois in Urbana-Champaign, funded by the National Science Foundation (NSF). Together, the collaboration aims to achieve regular disk-to-disk, end-to-end transfer rates of one petabyte per week between major facilities, which translates to achievable throughput rates of about 15 Gbps on real world science data sets. The number of sites with this base capability is also expanding, with Brookhaven National Laboratory in New York now testing its transfer capabilities with encouraging results. Future plans including bringing the NSF-funded San Diego Supercomputer Center and other big data sites into the mix.

“This increase in data transfer capability benefits projects across the DOE mission science portfolio” said Eli Dart, an ESnet network engineer and leader of the project. “HPC facilities are central to many collaborations, and they are becoming more important to more scientists as data rates and volumes increase. The ability to move data in and out of HPC facilities at scale is critical to the success of an ever-growing set of projects.”

Quantum Unveils Scale-out NAS for High-Value and Data-Intensive Workloads

Tue, 12/12/2017 - 08:51

SAN JOSE, Calif., Dec. 12, 2017 — Quantum Corp. (NYSE: QTM) today announced Xcellis Scale-out NAS, the industry’s first workflow storage appliance to provide the management capabilities and robust features of enterprise scale-out NAS with the cost-effective scaling organizations need to address modern data growth. It delivers greater than 3X the performance of competitive enterprise NAS offerings and, with integrated storage tiering, an end-to-end solution can cost as little as 1/10 that of alternative enterprise NAS solutions with the same capacity and performance. This combination makes Xcellis Scale-out NAS unique in comprehensively addressing the needs of high-value data environments where the organization’s revenue and products are all built around data.

Unified Unstructured Data at Scale 

Many IoT, media and entertainmentlife sciences, manufacturing, video surveillance and enterprise high-performance computing (HPC) environments are outgrowing traditional enterprise NAS. Users have typically turned to scale-out NAS over the past decade as an alternative but are finding that scaling capacity, integrating cloud strategies and sharing data are afterthoughts or not even possible with the solutions they’ve adopted. Unlike enterprise IT workloads, data in high-value workload environments is constantly growing on every axis — ingest, processing, analysis, distribution, archive. These environments require storage solutions with the management and features of enterprise NAS, but which can also cost-effectively scale performance and capacity. Leveraging Quantum’s industry-leading StorNext® parallel file system and data management platform, Xcellis Scale-out NAS offers industry-leading performance, scalability and management benefits for organizations with high-value workloads:

  • Cost-Effective Scaling of Performance and Capacity: Clusters can scale performance and capacity together or independently to reach hundreds of petabytes in capacity and terabytes per second in performance. A single client (SMB, NFS or high-performance client) can achieve over 3X the performance of competitive scale-out NAS offerings with multiple clients scaling a single cluster’s bandwidth to over a terabyte per second. In addition, an end-to-end solution with Xcellis has been shown to manage petabytes of data in a simplified workflow incorporating tape or cloud that provides greater performance than leading NAS-only alternatives for as little as a tenth of the cost.
  • Advanced Features and Flexible Management: With simple installation and setup, a modern administrative single-screen interface provides in-depth monitoring, alerting and management functions as well as rapid scanning and search capabilities that tame large data repositories. Xcellis Scale-out NAS is designed to integrate with the highest performance Ethernet networks through SMB and NFS interfaces and offers the flexibility to also support high-performance block storage in the same converged solution.
  • Lifecycle, Location and Cost Management: Xcellis Scale-out NAS leverages more than 15 years of data management experience built into StorNext. Xcellis data management provides automatic tiering between SSD, disk, tape, object storage and public cloud. Copies can be created for content distribution, collaboration, data protection and disaster recovery.

HPC-as-a-Service Finds Toehold in Iceland

Mon, 12/11/2017 - 14:20

While high-demand workloads (e.g., bitcoin mining) can overheat data center cooling capabilities, at least one data center infrastructure provider has announced an HPC-as-a-service offering that features 100 percent free and zero-carbon cooling.

Verne Global, a company seemingly intent on converting Iceland into a gigantic, renewably powered data center facility, has announce hpcDIRECT,  a scalable, bare metal service designed to support power-intensive high performance computing applications. Finding initial markets in the financial services, manufacturing (particularly automotive) and scientific research verticals, hpcDIRECT is powered by the island country’s abundant supply of hydroelectric, geothermal and, to a lesser degree, wind energy that the company says delivers 60 percent savings on power costs.

The launch follows Verne’s a late-October announcement that it had completed a 12.4-Tbps upgrade to the Greenland Connect subsea cable system with three 100-Gpbs connection to New York, lowering latency and delivering, according to Verne, up to 90 percent lower network costs.

hpcDIRECT is a response to customers who “want to consume their HPC in both the traditional sense, where we provide them with colocation capability, power space cooling – the traditional method a data center operator provides services to a customer – and then also to provide a next layer in the technology stack…the hardware and the orchestration of that hardware,” Dominic Ward, managing director at Verne, told EnterpriseTech.

He said hpcDIRECT is available with no upfront charges and can be provisioned to customers’ size and configuration requirements. hpcDIRECT clusters are built using updated architectures available, including Intel’s Xeon (Skylake) servers, connected with Mellanox EDR InfiniBand.

“By leveraging low-cost, reliable, and 100 percent renewable power at its Keflavik campus, the company holds a rather unique position compared to other providers in the industry that offer services similar to hpcDIRECT,” said Teddy Miller, associate analyst at industry watcher 451 Research. “Verne Global’s new product will appeal particularly to enterprises with corporate sustainability mandates or initiatives. The recent completion of an upgrade to Tele Greenland’s Greenland Connect subsea cable system should also significantly lower latency and network costs between the Keflavik campus and New York City. Verne Global may be small compared to other players in the space, but what it offers its customers is cheap, green and increasingly well-connected.”

Verne said hpcDIRECT is accessible via a range of options, from incremental additions to augment existing high performance computing, to supporting massive processing requirements with petaflops of compute. “This flexibility makes it an ideal solution for applications such as computer-aided engineering, genomic sequencing, molecular modelling, grid computing, artificial intelligence and machine learning” the company said.

Demand drivers in financial services for colocation data center services begin with the industry’s movement to reducing capex expenditures on the balance sheet and toward more efficient opex alternatives. Ward said banks and hedge fund companies typically run compute-intensive inter- and intra-day risk applications, “they often have a core level of compute that they want to augment with a more flexible and scalable solution.”

In the automotive sector, companies typically have CFD and crash simulation software running at high utilization 24/7/365. A service like hpcDIRECT, Ward said, “enables them to increment the compute resource they have for high performance applications on a steady basis.” This avoids time consuming and costly procurement cycles, he said. “We’re able to provide them an augmentation, or a complete replacement, for (their high-performance) resources and step into the demand profile that fits their compute demands.”

TOKYO, Dec. 11, 2017 — Fujitsu Laboratories Ltd. today announced the development of WAN acceleration technology that can deliver transfer speeds up to 40Gbps for migration of large volumes of data between clouds, using servers equipped with field-programmable gate arrays (FPGAs).

Connections in wide area networks (WANs) between clouds are moving from 1Gbps lines to 10Gbps lines, but with the recent advance of digital technology, including IoT and AI, there is an even greater demand for faster high-speed data transfers as huge volumes of data are collected in the cloud. Until now the effective transfer speed of WAN connections has been raised using techniques to reduce the volume of data, such as compression and deduplication. However, with WAN lines of 10Gbps there are enormous volumes of data to be processed, and existing WAN acceleration technologies usable in cloud servers have not been able to sufficiently raise the effective transfer rate.

Fujitsu Laboratories has now developed WAN acceleration technology capable of real-time operation even with speeds of 10Gbps or higher. WAN acceleration technology is achieved with a dedicated computational unit specialized for a variety of processing, such as feature value calculations and compression processing, mounted onto an FPGA equipped on a server, and in tandem with this, by enabling highly parallel operation of the computational units by supplying data at the appropriate times based on the predicted completion of each computation.

In a test environment where this technology was deployed on servers that use FPGAs, and where the servers were connected with 10Gbps lines, Fujitsu Laboratories confirmed that this technology achieved effective transfer rates of up to 40Gbps, the highest performance in the industry. With this technology, it has become possible to transfer data at high-speeds between clouds, including data sharing and backups, enabling the creation of next-generation cloud services that share and utilize large volumes of data across a variety of companies and locations.

Fujitsu Laboratories aims to deploy this technology, capable of use in cloud environments, as an application loaded on an FPGA-equipped server. It is continuing evaluations in practical environments with the goal of commercializing this technology during fiscal 2018.

Fujitsu Laboratories will announce details of this technology at the 2017 International Conference on Field-Programmable Technology (FPT 2017), an international conference to be held in Melbourne, Australia on December 11-13.

Development Background

As the cloud has grown in recent years, there has been a movement to increase data and server management and maintenance efficiency by migrating data (i.e., internal documents, design data, and email) that had been managed on internal servers to the cloud. In addition, as shown by the spread in the use of digital technology such as IoT and AI, there are high expectations for the ways that work and business will be transformed by the analysis and use of large volumes of data, including camera images from factories and other on-site locations, and log data from devices. Given this, there has been explosive growth in the volume of data passing through WAN lines between clouds, spurring a need for next-generation WAN acceleration technology capable of huge data transfers at high-speed between clouds.


WAN acceleration technologies improve effective transfer speeds by reducing the volume of data through compression or deduplication of the data to be transferred. When transferring data at even higher speeds using 10Gbps network lines, the volume of data needing to be processed is so great that the compression and deduplication processing speed in the server bottlenecks. Therefore, in order to improve real-time operation, there is a need for either CPUs that can operate at higher speeds, or for WAN acceleration technology with faster processing speeds.

About the Newly Developed Technology

Fujitsu Laboratories has now developed WAN acceleration technology that can achieve real-time operation usable in the cloud even with speeds of 10Gbps or more, using server-mounted FPGAs as accelerators. Efficient operations with WAN acceleration technology are accomplished by using an FPGA to process a portion of the processing for which the computation is heavy and for which it is difficult to improve processing speed in the CPU, when performing compression or deduplication for WAN acceleration processing, and by efficiently connecting the CPU with the FPGA accelerator. Details of the technology are as follows.

1. FPGA parallelization technology using highly parallel dedicated computational units

Fujitsu Laboratories has developed FPGA parallelization technology that can significantly reduce the processing time required for data compression and deduplication by deploying dedicated computational units specialized for data partitioning, feature value calculation, and lossless compression processing in a FPGA in a highly parallel configuration, and by enabling highly parallel operation of the computational units by delivering data at the appropriate times based on predictions of the completion of each calculation.

2. Technology to optimize the flow of processing between CPU and FPGA

Previously, in determining whether to apply lossless compression to data based on the identification of duplication in that data, it was necessary to read the data twice, both before and after the duplication identification was executed on the FPGA, increasing overhead and preventing the system from delivering sufficient performance. Now, by consolidating the processing handoff onto the FPGA, handling both the preprocessing for duplication identification and the compression processing on the FPGA, and using a processing sequence that controls how the compression processing results are reflected on the CPU based on the results of the duplication identification, this technology reduces the overhead between the CPU and FPGA from reloading the input data and from control exchanges. This reduces the waiting time due to the handoff of data and control between the CPU and FPGA, delivering efficient coordinated operation of the CPU and FPGA accelerator.


Fujitsu Laboratories deployed this newly developed technology in servers installed with FPGAs, confirming acceleration approximately thirty times the performance of CPU processing alone. Fujitsu Laboratories evaluated the transfer speed for a high volume of data in a test environment where the servers were connected with 10Gbps connections, and in a test simulating the regular backup of data, including documents and video, confirmed that this technology achieved transfer speeds up to 40Gbps, an industry record. This technology has significantly improved data transfer efficiency over WAN connections, enabling high-speed data transfers between clouds, such as data sharing and backups, making possible the creation of next-generation cloud services that share and use large volumes of data between a variety of companies and locations.

Future Plans

Fujitsu Laboratories will continue to evaluate this technology in practical environments, deploying this technology in virtual appliances that can be used in cloud environments. Fujitsu Laboratories aims to make this technology available as a product of Fujitsu Limited during fiscal 2018.

HPC Iron, Soft, Data, People – It Takes an Ecosystem!

Mon, 12/11/2017 - 09:53

Cutting edge advanced computing hardware (aka big iron) does not stand by itself. These computers are the pinnacle of a myriad of technologies that must be carefully woven together by people to create the computational capabilities that are used to deliver insights into the behaviors of complex systems. This collection of technologies and people has been called the High Performance Computing (HPC) ecosystem. This is an appropriate metaphor because it evokes the complicated nature of the interdependent elements needed to deliver first of a kind computing systems.

The idea of the HPC ecosystem has been around for years and most recently appeared in one of the objectives for the National Strategic Computing Initiative (NSCI). The 4th objective calls for “Increasing the capacity and capability of an enduring national HPC ecosystem.” This leads to the questions of, “what makes up the HPC ecosystem” and why is it so important? Perhaps the more important question is, why does the United States need to be careful about letting its HPC ecosystem diminish?

The heart of the HPC ecosystem is clearly the “big humming boxes” that contain the advanced computing hardware. The rows upon rows of cabinets are the focal point of the electronic components, operating software, and application programs that provide the capabilities that produce the results used to create new scientific and engineering insights that are the real purpose of the HPC ecosystem. However, it is misleading to think that any one computer at any one time is sufficient to make up an ecosystem. Rather, the HPC ecosystem requires a continuous pipeline of computer hardware and software. It is that continuous flow of developing technologies that keeps HPC progressing on the cutting edge.

The hardware element of the pipeline includes systems and components that are under development, but are not currently available. This includes the basic research that will create the scientific discoveries that enable new approaches to computer designs. The ongoing demand for “cutting edge” systems is important to keep system and component designers pushing the performance envelope. The pipeline also includes the currently installed highest performance systems. These are the systems that are being tested and optimized. Every time a system like this is installed, technology surprises are found that must be identified and accommodated. The hardware pipeline also includes systems on the trailing edge. At this point, the computer hardware is quite stable and allows a focus on developing and optimizing modeling and simulation applications.

One of the greatest challenges of maintaining the HPC ecosystem is recognizing that there are significant financial commitments needed to keep the pipeline filled. There are many examples of organizations that believed that buying a single big computer would make them part of the ecosystem. In those cases, they were right, but only temporarily. Being part of the HPC ecosystem requires being committed to buying the next cutting-edge system based on the lessons learned from the last system.

Another critical element of the HPC ecosystem is software. This generally falls into two categories – software needed to operate the computer (also called middleware or the “stack”) and software that provides insights into end user questions (called applications). Middleware plays the critical role of managing the operations of the hardware systems and enabling the execution of applications software. Middleware includes computer operating systems, file systems and network controllers. This type of software also includes compilers that translate application programs into the machine language that will be executed on hardware. There are quite a number of other pieces of middleware software that include libraries of commonly needed functions, programming tools, performance monitors, and debuggers.

Applications software span a wide range and are as varied as the problems users want to address through computation. Some applications are quick “throwaway” (prototype) attempts to explore potential ways in which computers may be used to address a problem. Other applications software is written, sometimes with different solution methods, to simulate physical behaviors of complex systems. This software will sometimes last for decades and will be progressively improved. An important aspect of these types of applications is the experimental validation data that provide confidence that the results can be trusted. For this type of applications software, setting up the problem that can include finite element mesh generation, populating that mesh with material properties and launching the execution are important parts of the ecosystem. Other elements of usability of application software include the computers, software, and displays that allow users to visualize and explore simulation results.

Data is yet another essential element of the HPC ecosystem. Data is the lifeblood in the circulatory system that flows through the system to keep it doing useful things. The HPC ecosystem includes systems that hold and move data from one element to another. Hardware aspects of the data system include memory, storage devices, and networking. Also software device drivers and file systems are needed to keep track of the data. With the growing trend to add machine learning and artificial intelligence to the HPC ecosystem, its ability to process and productively use data are becoming increasingly significant.

Finally, and most importantly, trained and highly skilled people are an essential part of the HPC ecosystem. Just like computing systems, these people make up a “pipeline” that starts in elementary school and continues through undergraduate and then advanced degrees. Attracting and educating these people in computing technologies is critical. Another important part of the people pipeline of the HPC ecosystem are the jobs offered by academia, national labs, government, and industry. These professional experiences provide the opportunities needed to practice and hone HPC skills.

The origins of the United States’ HPC ecosystem dates back to the decision by the U.S. Army Research Lab to procure an electronic computer to calculate ballistic tables for its artillery during World War II (i.e. ENIAC). That event led to finding and training the people, who in many cases were women, to program and operate the computer. The ENIAC was just the start of the nation’s significant investment in hardware, middleware software, and applications. However, just because the United States was the first does not mean that it was alone. Europe and Japan also have robust HPC ecosystems for years and most recently China has determinedly set out to create one of their own.

The United States and other countries made the necessary investments in their HPC ecosystems because they understood the strategic advantages that staying at the cutting edge of computing provides. These well-document advantages apply to many areas that include: national security, discovery science, economic competitiveness, energy security and curing diseases.

The challenge of maintaining the HPC ecosystem is that, just like a natural ecosystem, the HPC version can be threatened by becoming too narrow and lacking diversity. This applies to the hardware, middleware, and applications software. Betting on just a few types of technologies can be disastrous if one approach fails. Diversity also means having and using a healthy range of systems that covers the highest performance cutting edge systems to wide deployment of mid and low-end production systems. Another aspect of diversity is the range of applications that can productively use on advanced computing resources.

Perhaps the greatest challenge to an ecosystem is complacency and assuming that it, and the necessary people, will always be there. This can take the form of an attitude that it is good enough to become a HPC technology follower and acceptable to purchase HPC systems and services from other nations. Once a HPC ecosystem has been lost, it is not clear if it can be regained. Having a robust HPC ecosystem can last for decades, through many “half lives” of hardware. A healthy ecosystem allows puts countries in a leadership position and this means the ability to influence HPC technologies in ways that best serve their strategic goals. Happily, the 4th NSCI objective signals that the United States understands these challenges and the importance of maintaining a healthy HPC ecosystem.

Intel® Omni-Path Architecture and Intel® Xeon® Scalable Processor Family Enable Breakthrough Science on 13.7 petaFLOPS MareNostrum 4

Mon, 12/11/2017 - 08:49

In publicly and privately funded computational science research, dollars (or Euros in this case) follow FLOPS. And when you’re one of the leading computing centers in Europe with a reputation around the world of highly reliable, leading edge technology resources, you look for the best in supercomputing in order to continue supporting breakthrough research. Thus, Barcelona Supercomputing Center (BSC) is driven to build leading supercomputing clusters for its research clients in the public and private sectors.

MareNostrum 4 is nestled within the Torre Girona chapel

“We have the privilege of users coming back to us each year to run their projects,” said Sergio Girona, BSC’s Operations Department Director. “They return because we reliably provide the technology and services they need year after year, and because our systems are of the highest level.” Supported by the Spanish and Catalan governments and funded by the Ministry of Economy and Competitiveness with €34 million in 2015, BSC sought to take its MareNostrum 3 system to the next-generation of computing capabilities. It specified multiple clusters for both general computational needs of ongoing research, and for development of next-generation codes based on emerging supercomputing technologies and tools for the Exascale computing era. It fell to IBM, who partnered with Fujitsu and Lenovo, to design and build MareNostrum 4.

MareNostrum 4 is a multi-cluster system which main cluster and data storage are interconnected by the Intel® Omni-Path Architecture (Intel® OPA) fabric. A general-purpose compute cluster, with 3,456 nodes of Intel® Xeon® Scalable Processor Product Family will provide up to 11.1 petaFLOPS of computational capacity. A smaller cluster delivering up to 0.5 petaFLOPS is built on the Intel® Xeon Phi Processor 7250. A third small cluster up to 1.5 petaFLOPS will include Power9* and Nvidia GPUs, and a fourth one, made of ARM v8 processors, will provide other 0.5 petaFLOPS of performance. And an IBM storage array will round out the system. All systems are interconnected with the storage subsystem. MareNostrum 4 is designed to be twelve times faster than its predecessor.

Spain’s 13.7 petaFLOPS supercomputer contributes to the Partnership for Advanced Computing in Europe (PRACE) and supports the Spanish Supercomputing Network (RES).

“From my point of view,” stated Girona, “Intel had, at the time of the procurement, the best processor for general purpose systems. Intel is very good on specific domains, and they continue to innovate in other domains. That is why we chose Intel processors for the general-purpose cluster and Intel Xeon Phi Processor for one of the emerging technology clusters, on which we can explore new code development.” The system was in production by July 2017 and placed at number 13 in the June 2017 Top500 list and number 16 on the November 2017 list.

“The Barcelona Supercomputing Center team is committed to maximizing MareNostrum in any way we can,” concluded Girona. “But MareNostrum is not about us. Our purpose at BSC is to help others. We are successful when the scientists and engineers using MareNostrum’s computing power get all the data they need to further their discoveries. It is always rewarding to know we help others to further cutting-edge scientific exploration.”

The Stanford Living Heart Project Wins Prestigious HPC Awards During SC17

Thu, 12/07/2017 - 16:15

Dec. 7 — During SC’17, the 30th International Conference for High Performance Computing, Networking, Storage and Analysis in Denver, in November, UberCloud – on behalf of the Stanford Living Heart Project – received three HPC awards. It started at the preceding Intel HPC Developer Conference when the Living Heart Project (LHP), presented by Burak Yenier from UberCloud, won a best paper award. During SC’17 on Monday, the Stanford LHP Team received the HPCwire Editors’ Choice Award for Best Use of HPC in the Cloud. And finally, on Tuesday, the team won the Hyperion (former IDC) Award for Innovation Excellence, elected by the Steering Committee of the HPC User Forum.

The Stanford LHP project dealt with simulating cardiac arrhythmia which can be an undesirable and potentially lethal side effect of drugs. During this condition, the electrical activity of the heart turns chaotic, decimating its pumping function, thus diminishing the circulation of blood through the body. Some kind of cardiac arrhythmia, if not treated with a defibrillator, will cause death within minutes.

Before a new drug reaches the market, pharmaceutical companies need to check for the risk of inducing arrhythmias. Currently, this process takes years and involves costly animal and human studies. In this project, the Living Matter Laboratory of Stanford University developed a new software tool enabling drug developers to quickly assess the viability of a new compound. This means better and safer drugs reaching the market to improve patients’ lives.

A computational model that is able to assess the response of new drug compounds rapidly and inexpensively is of great interest for pharmaceutical companies, doctors, and patients. Such a tool will increase the number of successful drugs that reach the market, while decreasing cost and time to develop them, and thus help hundreds of thousands of patients in the future. However, the creation of a suitable model requires taking a multiscale approach that is computationally expensive: the electrical activity of cells is modelled in high detail and resolved simultaneously in the entire heart. Due to the fast dynamics that occur in this problem, the spatial and temporal resolutions are highly demanding.

CMU, PSC and Pitt to Build Brain Data Repository

Thu, 12/07/2017 - 11:12

Dec. 7, 2017 — Researchers with Carnegie Mellon’s Molecular Biosensor and Imaging Center (MBIC), the Pittsburgh Supercomputing Center (PSC) and the University of Pittsburgh’s Center for Biological Imaging (CBI) will help to usher in an era of open data research in neuroscience by building a confocal fluorescence microscopy data repository. The data archive will give researchers easy, searchable access to petabytes of existing data.

The project is funded by a $5 million, five-year grant from the National Institutes of Health’s (NIH’s) National Institute of Mental Health (MH114793) and is part of the federal BRAIN initiative.

“This grant is a testament to the fact that Pittsburgh is a leader in the fields of neuroscience, imaging and computer science,” said Marcel Bruchez, MBIC director, professor of biological sciences and chemistry at Carnegie Mellon and co-principal investigator of the grant. “By merging these disciplines, we will create a tool that helps the entire neuroscience community advance our understanding of the brain at an even faster pace.”

New imaging tools and technologies, like large-volume confocal fluorescence microscopy, have greatly accelerated neuroscience research in the past five years by allowing researchers to image large regions of the brain at such a high level of resolution that they can zoom in to the level of a single neuron or synapse, or zoom out to the level of the whole brain. These images, however, contain such a large amount of data that only a small part of one brain’s worth of data can be accessed at a time using a standard desktop computer. Additionally, images are often collected in different ways — at different resolutions, using different methodologies and different orientations. Comparing and combining data from multiple whole brains and datasets requires the power of supercomputing.

“PSC has a long experience with handling massive datasets for its users, as well as a deep skillset in processing microscopic images with high-performance computing,” said Alex Ropelewski, director of PSC’s Biomedical Applications Group and a co-principal investigator in the NIH grant. “This partnership with MBIC and CBI was a natural step in the ongoing collaborations between the institutions.”

The Pittsburgh-based team will bring together MBIC and CBI’s expertise in cell imaging and microscopy and pair it with the PSC’s long history of experience in biomedical supercomputing to create a system called the Brain Imaging Archive. Researchers will be able to submit their whole brain images, along with metadata about the images, to the archive. There the data will be indexed into a searchable system that can be accessed using the internet. Researchers can search the system to find existing data that will help them narrow down their research targets, making research much more efficient.
