Abstract

The process of gathering, archiving, and distributing computerbenchmark data is a cumbersome task usually performed by computerusers and vendors with little coordination. Most important, thereis no publicly available central depository of performance data forall ranges of machines from personal computers to supercomputers.We present an Internet-accessible performance database server (PDS)that can be used to extract current benchmark data and literature.As an extension to the X-Windows-based user interface (Xnetlib) tothe Netlib archival system, PDS provides an on-line catalog ofpublic domain computer benchmarks such as the LINPACK benchmark,Perfect benchmarks, and the NAS parallel benchmarks. PDS does notreformat or present the benchmark data in any way that conflictswith the original methodology of any particular benchmark; it isthereby devoid of any subjective interpretations of machineperformance. We believe that all branches (research laboratories,academia, and industry) of the general computing community can usethis facility to archive performance metrics and make them readilyavailable to the public. PDS can provide a more manageable approachto the development and support of a large dynamic database ofpublished performance metrics.
