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
- performance optimisation in the OF source code
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
1.2 Links
