University of Colorado Boulder Research Computing

CU Boulder research computing strives to elevate the knowledge of research computing on the Boulder campus. Their mission is to promote the integration of computing resources, software, and networking, along with data storage, information management, and human resources in order to advance scholarship and research as a fundamental goal of cyberinfrastructure (CI). The research computing group works to provide leadership in developing, deploying, and operating such an an integrated CI to allow CU Boulder to achieve further preeminence as a research university.

CU Boulder Research Computing offers state of the art computing facilities including a filesystem storage, a Dell M1000e chassis filled with 16 blades, and three high memory nodes. Research Computing has several nodes dedicated to GridFTP file transfer. The JANUS supercomputer is comprised of 1368 compute nodes, each containing 12 cores, for a total 16,416 available cores. JANUS can achieve 184 TFLOPS (Trillion Floating Point Operations). Here are some details.

  • Default OS - Redhat 5.5 Enterprise.
  • 1368 compute nodes (4 nodes per Chassis, 342 Chassis)
  • 16416 total cores (Each node contains two hex-core 2.8Ghz Intel Westmere processors for 12 cores per node.)
  • 2GB of RAM per core
  • 24GB RAM per node (about 20GB free with the base image loaded)32TB total system RAM
  • Approximately 800TB of high performance storage is accessible via a Lustre filesystem.

From garnering NASA research funding to creating 4 Nobel Laureates, CU Boulder's research department has been realizing astonishing results since 1877. Their research institutes include the Alliance for Technology, Learning and Society, the Cooperative Institute for Research in Environmental Sciences, the Institute for Behavioral Genetics, the Institute for Artic and Alpine Research, the Institute of Behavioral Science, the Institute of Cognitive Science, JILA, the Laboratory for Atmospheric and Space Physics, the Renewable and Sustainable Energy Institute, and the University of Colorado Museum of Natural History. Most recently, Research Computing and the Janus Supercomputer have become integrated in the University’s goal in leading research processing. The goal of Research Computing is the integration of computing resources, software, and networking, along with data storage, information management, and human resources to advance scholarship and research is a fundamental goal of cyberinfrastructure (CI). Such integration creates opportunities for researchers, educators, and learners to share ideas, expertise, tools, and facilities in new and powerful ways that cannot be realized if each of these components is applied independently. Bridging the gap between the reality of CI today and its potential in the immediate future is critical to building a balanced CI ecosystem that can support future scholarship and research activities.
