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.
| Case nr | solver | case-name | Modification to original case | Memory usage | Baseline time | Remarks/Problems |
|---|---|---|---|---|---|---|
| 1 | dieselFoam | aachenBomb | files are removed before running | 275 MB | 2894 s | Parallel run fails for v1.2: the patch published here fixes this |

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.
| Machine name | Machine description | OF version | Overall speedup | Individual speedups | Remarks | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | |||||
| Apple iBook G4 | PPC G4 , 1.42 Ghz, 0.5 GB, Mac OS X 10.4 | 1.2 (Downloaded from Hrv) | 0.637 | 0.642 | 0.633 | 0.609 | 0.580 | 0.661 | 0.626 | 0.667 | 0.611 | 0.590 | 0.698 | 0.690 | |
| Reference Machine | Pentium 4, 1.8 Ghz, 1GB, Linux | 1.2 Standard | 1.0 | 1.0 | 1.0 | 1.0 | 1.0 | 1.0 | 1.0 | 1.0 | 1.0 | 1.0 | 1.0 | 1.0 | |
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).
