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)

Valid versions: OF version 12.png OF version 13.png

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 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'.

4 Comparing OpenFOAM-versions

Valid versions: OF version 10.png OF version 11.png

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
