Jeff, The PGI/nVidia compiler suite is free now and could become more significant in the ARM world, now that nVidia has acquired ARM. We use PGI on our cluster, along with the others you support.

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? Or is it worthwhile to test other versions of these compilers? -- Jeff Squyres jsquy...@cisco.com<mailto:jsquy...@cisco.com> Larry Baker US Geological Survey 650-329-5608 ba...@usgs.gov<mailto:ba...@usgs.gov>
