Benchmarks standard v1
From OpenFOAMWiki
These are benchmarks generated with the benchFoam-script which is part of the PyFoam-distribution version 0.2.4. To compare with the results on this page use the config file standard_v1.cfg (this is not going to change anymore, standard.cfg is an ongoing effort and will eventually become standard_v2.cfg)

1 The suite
This is a short description of the cases in this benchmark suite. All the cases run with an unmodified OpenFOAM v1.2 in serial mode. Case 2 won't run in parallel. To run case 1 in parallel a patch has to be applied and parts of OpenFOAM have to be recompiled.
- Memory usage is rounded to the nearest whole number.
- Baseline-times are rounded to the nearest whole number

2.2 Parallel results
Please note that some of the cases in the suite are very small and therefor may lead to speedups smaller than 1 (especially for distributed memory machines).
Some of the cases included in the suite are too small to make a parallel machine 'look good'.

4 Comparing OpenFOAM-versions
Valid versions: 
This is ancient history because using older OpenFOAM-versions is not recommended but there is a modified version of the standard_v1.cfg called standard_v1_pre12.cfg in PyFoam-distribution version 0.2.5 that makes it possible to run the benchmark suite on two older versions. The results on the reference machine are:

- Version 1.0 and 1.2 were recompiled but the standard-switches were used
- the tutorial cases delivered with the corresponding version were used
- in case 7 the deltaT had to be multiplied by 10 (otherwise the speedup compared with 1.2 would have been 0.11)
- if someone wants to test the parallel-versions he is welcome to do so
