Summary

• Commodity-based and High-end Systems

  • Commodity Systems under evaluation ; CS1 – CS20
  • High-end systems from SGI, IBM and HP/Compaq
  • Serial CPU and Communications Performance; Evaluation Metrics

• Application performance

  • Molecular Simulation (replicated & distributed data)
    • DL_POLY, DLMULTI and CHARMM
  • Molecular Electronic Structure & Materials Simulation
    • NWChem, GAMESS-UK and CPMD
  • Computational Engineering
    • ANGUS, SBLI

• Notable Performance of Opteron clusters with Myrinet:

  • CS20 Opteron248/2200 cluster with Myrinet delivers on average 100% of SGI Altix 3700/1300.
  • Cost effectiveness of the Clusters (e.g., CS18) with Gbit Ethernet - delivers 49% of the SGI Altix 3700/1300 .
