SUMMARY

• Processor Performance Overview

  • Single-processor performance, Performance Metrics

• SPECfp and Computational Chemistry Benchmark (serial)

  • Matrix’89 and Matrix’97 kernels (MMO, diagonalisation), Application kernels” (SCF, MD, QMC and JACOBI + STREAM), Application packages (GAMESS-UK, DL_POLY)

• Increasing importance of Rate-based benchmarks:

  • SPECfp_rate and Chemistry Rate Benchmark

• Machine COSTS vs. Performance: URLs:

  • Powerpoint presentation and Paper:

• Benchmarking & Evaluation of Commodity-based Systems

  • 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.
