Hi Passant, list This is an old problem with PGI. There are many threads in the OpenMPI mailing list archives about this, with workarounds. The simplest is to use FC="pgf90 -noswitcherror".
Here are two out of many threads ... well, not pthreads! :) https://www.mail-archive.com/users@lists.open-mpi.org/msg08962.html https://www.mail-archive.com/users@lists.open-mpi.org/msg10375.html I hope this helps, Gus Correa On Thu, Jan 14, 2021 at 5:45 PM Passant A.
