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

1.2 Links

Cross checking OpenFOAM and Fluent results of CFD simulations in ENEA-GRID environment
