  1. State of the CCS SOS 8 April 13, 2004 James B. White III (Trey) trey@ornl.gov virtual Buddy Bland

  2. State of the CCS • CCS as a user facility • CCS as a DOE Advanced Computing Research Testbed (ACRT) • Future plans

  3. Facilities • Computer facility • 40,000 ft2 over two floors • 36” raised floor (lower floor) • 8 MW power, 3600 tons cooling • Office space for 450 • Classrooms and training areas • Labs for visualization, computer science, and networking

  4. User Facility • CCS designated by DOE as a user facility • Supports users from academia and industry • Pursuing agreements with Boeing and Dow Chemical

  5. 70% of usage is from users outside of ORNL User Community Users come from all around the country

  6. FY03 Usage by Discipline

  7. CCS Usage Model • Small number of large projects • CCS supports liaisons for large projects • Center can be dedicated to single task of national importance • Human genome • HFIR restart • IPCC

  8. Advanced Computing Research Testbed • ACRT examines promising new computer architectures for DOE SC • Determine usability for SC applications • Work with vendors to improve systems • Application-based evaluations

  9. Intel i/PSC-2 1988 SRC Prototype 1999 KSR-1 1991 GSN Switch 2000 Compaq AlphaServer SC 2000 IBM Power4 and Federation 2001-2004 Intel Paragon XP/S-35 1992 Intel Paragon MP X/PS-150 1995 IBM S80 1999 Intel I/PSC-860 1990 IBM Winterhawk And Nighthawk 1999 Past Evaluations

  10. Current Evaluations • Cray X1 - scalable vector • SGI Altix - large shared memory • IBM Federation Cluster - interconnect • http://www.csm.ornl.gov/evaluation/

  11. Cray X1 • World’s largest X1 • 8 cabinets • 256 MSPs, 3.2 TF • 1 TB memory • 32 TB local disk • Cabinets half populated to test topology and facilitate upgrade

  12. SGI Altix • Large memory, single-system image • 256 Itanium2 processors • 1.5 GHz, 6 GF, 6 MB cache • 1.5 TF • 2 TB shared memory (NUMA) • Targeting biology apps and data analysis
