| 0001759 | OpenFOAM | Bug | public | 2015-06-22 21:21 | 2015-06-23 11:28 |
| Reporter | Assigned To | henry | |||
| Priority | normal | Severity | major | Reproducibility | always |
| Status | resolved | Resolution | fixed | ||
| Platform | ppc64el | OS | Ubuntu/Debian | OS Version | 15.04 |
| Summary | 0001759: OpenFOAM does not build on ppc64le architecture | ||||
| Description | Ppc64le is the new ABI for POWER architecture. It now runs on little endian mode, as started to run on POWER8 processors. For more information about it, check [1]. Currently openFOAM does not build on this architecture, and says that ppc64le (from uname -m) architecture is not known. I am adding a patch that adds initial support for this architecture. [1] https://wiki.debian.org/ppc64el#ABI_Documentation | ||||
| Steps To Reproduce | # wmake all | ||||
| Additional Information | If you want access to a ppc64el machine, we are please to give you one. Just ask it at http://openpower.ic.unicamp.br/minicloud/ and says that this is related to OpenFOAM porting. | ||||

I am happy to include support for the ppc64le architecture. What is the performance of OpenFOAM like on POWER8 compared to Xeon for example? |
