Re: [OMPI devel] Which compiler versions to test?
Sorry, keep forgetting to reply. I think your list is a reasonable starting point. I think AWS is still a little thin in its OS/compiler testing, we definitely have room to improve there. We probably won't pick up the older Intel compilers, for various reasons. We are running recent Intel Compilers with TCP and EFA (but obviously not usnic). I think your list is pretty reasonable for compilers, and we should probably pick up more here along the way. If I were you and had to prune, I'd probably prune the GCC 9 / CLANG 9...

I doubt I have enough time to set that up, but I can certainly get gcc 8.3.1 installed and added to my list. It's probably "close enough" to RHEL's 8.3.1 for MTT purposes. -- Jeff Squyres jsquy...@cisco.com
Re: [OMPI devel] Which compiler versions to test?
Hi Jeff, On RHEL 8.x, the default gcc compiler is 8.3.1, so I think it is worth testing. Containers could be used to setup a RHEL 8.x environment (so not only gcc but also third party libs such as libevent and hwloc can be used) if the MTT cluster will not shrink bigger.

[OMPI devel] Which compiler versions to test?
Open question to the Open MPI dev community... Over time, the size of my MTT cluster has been growing smaller (due to hardware failure, power budget restrictions, etc.). This means that I have far fewer CPU cycles available for testing various compilers and configure CLI options than I used to. What compilers does the community think are worthwhile to test these days? I generally have access to gcc/gfortran, clang, and some versions of the Intel compiler suite. master, 4.0.x, and 4.1.x branches - gcc 4.8.5 (i.e., the default gcc on RHEL 7.x) - gcc 9.latest - gcc 10.latest - clang 9.0.latest - clang 10.0.latest - Intel 2017 - Intel 2019 (I don't have Intel 2018 or Intel 2020) Is this sufficient?
