Benchmarks standard v1
From OpenFOAMWiki
These are benchmarks generated with the benchFoam-script which is part of the PyFoam-distribution version 0.2.4.

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.

2 Results overview
2.1 Serial results
First column is a reference to a machine description below. Second column gives a brief summary of the machine. The OpenFOAM version used is in column 3. Then follows the overall speedup and the speedups for the individual cases.
The benchmarks are ordered by the overall speedup in ascending order.

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'.

- Remarks
- The OpenFOAM installation and the data directories were on remote machines and mounted via NFS (Network is 100Mbit), On the machine a OpenGroupware-server was running, but the benchmarks were running at night when this server wasn't used so this shouldn't have an impact
