2
863 effort on HPC
  • Early 1990s from intelligent computers to
    parallel computers
  • Intelligent Computer RD Center established
  • 1993 Dawning 1, 640MIPS, SMP
  • 1995 Dawning 1000, 2.5GFlops, MPP
  • 1996 Dawning 1000A, cluster system
  • 1998 Dawning 2000, 100GFlops, cluster
  • 2000 Dawning 3000, 400GFlops, cluster,
    comercialized

3
863 effort on HPC
  • 2002 Lenovo DeepComp 1800, 1TFlops, cluster
  • 2003 Lenovo DeepComp 6800, 5.324TFlops, cluster,
    14th in TOP500
  • 2004 Dawning 4000A, 11.2TFlops, 10th in TOP500
  • 2004 Inspur high end enterprise servers T20000,
    up to 4TFlops

4
Other efforts on HPC
  • Blade cluster (Galactic Computing)
  • Clusters in universities
  • Tsinghua University
  • Shanghai University

5
Shift of emphasis
  • From pursuing peak performance to pursuing
    scalability, usability, maintainability, and
    availability (SUMA)
  • Commercialization
  • Compatibility to main steam systems, supporting
    commercial software

6
Growing applications
  • Applications from traditional areas (weather
    forecast, petro exploration) to much wider range
    of applications
  • Bioinformatics
  • Drug discovery
  • Computational chemistry
  • Materials
  • Environment
  • Manufacturing
  • Simulation

7
Fast increase in HPC installations
  • 2002 0.6 TFlops in TOP500
  • End of 2006 94 TFlops in TOP500
  • Terascale systems in major universities,
    institutes, and enterprises

8
Education/Training
  • Training programme introduced in universities
  • Practical training in application organizations
  • Textbooks (translations) on parallel computing,
    algorithms and applications

9
HPC Environment
  • 1999-2000 National High Performance Computing
    Environment (NHPCE)
  • 2002-present CNGrid
  • 10 sites
  • 18 TFlops
  • gt200TB storage
  • 2003-present ChinaGrid (20 universities)

10
CNGrid nodes locations
11
Complementary RD in HPC Grid
  • HPCs provide major resources to Grid
  • Grid enables easy access to HPC resources and
    makes HPC available to a much wide user population

12
Complementary RD in HPC Grid
  • Since 1998, 863 programme begin effort in HPC
    environment, resulting NHPCE, Grid term was first
    introduced
  • 2002-2005 863 key project on HPC and core
    software, focused on Grid, resulting in CNGird
  • 2006-present 863 key project on HPC and Grid
    service environment, significant upgrading of
    CNGrid resources, software, and applications

13
CAS Supercomputing Center (SCCAS)
  • Equipped with Lenovo DeepComp 6800, 5.324TFlops
  • Average utilization 86
  • Applications
  • gt180 registered users
  • Supporting more than 120 important projects
  • Important achievements
