** Update 2: I have created a page on the OpenFOAM wiki: https://openfoamwiki.net/index.php/Benchmarks . The updated plot will now be found there as I will eventually not be able to edit this post. But please continue to contribute further benchmarks in this thread! **
** Update: I have now added a plot with minimum time to solution for all hardware posted in this thread! I will try to keep this updated as more results are posted. Thank you for all the contributions! ** Hi, I promised in another thread here to run some OpenFOAM benchmarks on different Intel hardware that I have available, so here they are. These are based on the motorBike benchmark, but I modified it to have more grid cells, run fewer iterations and to use scotch decomposition. You can find the full setup in the attached tar.gz-file. If you want to test on your hardware, you only need to run the run.sh script (you only need to change the number of cores in the three for loops if you want to run on a different number of cores). It would be interesting if more people could contribute to generate a modest database of benchmarks here. The below table shows runtime in seconds. There is also a graph which shows the speedup. Some observations, most relatively obvious :
Code:
# Gold 6148 8x E7-8870 2x E5-2695 v2 2x E5-2643 v3 2x E5-2695 v4 1 874 2132 1451 883 1084 2 435 1124 597 468 578 4 225 476 281 215 273 6 164 297 205 153 189 8 136 203 178 126 146 12 111 148 150 101 104 16 101 104 140 85 20 98 92 137 76 24 77 137 71 36 64 65 ---MODERATOR NOTE--- The original bench template requires some tweaks in order to work with more recent versions of OpenFOAM. Try using bench_template_v02 for the openfoam.org versions instead, courtesy of Simbelmynė For the openfoam.com versions (e.g. v2112) this script should work out of the box: OpenFOAM benchmarks on various hardware bench_template_v02.zip Newer performance charts provided by naffrancois with much more entries Maximum performance: https://ibb.co/MsQh94V Single-core performance: https://ibb.co/GVnbYP5 MS Excel file with the numbers: bdd_cpu_cfdonline.xlsx Last edited by flotus1; November 13, 2022 at 15:52. Reason: bench template outdated |
