Is there a table somewhere that tells me what version of things like libfabric and UCX (and maybe compiler versions if there are known issues) are known to be good with which versions of OpenMPI? I poked around in the README, FAQ, Download sections and for the life of me can't seem to find it. I don't think we have a definitive list like this, sorry. In general, the latest versions of dependent packages are generally a good bet. Compiler support has been pretty stable for a while. The UCX folks recently wondered if they should stop supporting anything before 1.9.0 (see https://github.com/open-mpi/ompi/issues/8321#issuecomment-769951617). So if you're using UCX, perhaps go with that. For Libfabric, I'd generally say the same thing: use the most recent release and you should be ok. -- Jeff Squyres jsquy...@cisco.com<mailto:jsquy...@cisco.com>
