1 General

During the BoF sessions of the OF Workshop 2009 in Montreal a session on High Performance Computing (HPC) was held.

Results of this session were:

  • OF is often used in a HPC environment
  • A collection of benchmarking results of OF on various hardware should be started to form a basis for
    • performance optimisation in the OF source code
    • hardware recommondations

1.1 Benchmark

Criteria for a universal benchmarking case need to be defined and the benchmarking case made available. Furthermore a questionnaire describing the performance crucial hardware components should be created to form a basis for analysis of benchmark results.

1.1.1 Benchmark case

TODO: Find a more or less universal benchmarking case. Preferably the case does not need a complex mesh / solver. The icoFoam cavity tutorial could be a first starting point.

1.1.2 Hardware description

TODO: Define a list of key hardware components that sufficiently precise describe the benchmarked system.

  • CPU
  • Memory
  • Inter-connect
