Hello,
Starting from Parallel Studio 2019 Update 1, mpiexec fails to run any executable. Example: "mpiexec -np 1 /bin/ls". Any call to mpiexec (except calls like "mpiexec -help") results in Segmentation fault.
Please help. I can provide additional information if necessary. However testing is a bit complicated because I had to revert to the Initial release, and Updates cannot be installed concurrently AFAIK, so please request testing only if absolutely necessary.
Note 1: It is on Linux Mint 19. As you may know, this distribution is heavily based on Ubuntu 18.04. By "heavily" I mean that only cosmetic packages differ, like the desktop environment packages. System packages (libc and the like) are taken directly from the Ubuntu repositories.
Note 2: This problem was originally reported in the C++ compiler forum, here. It was spotted on Opensuse (which shares most code with SLES, a distribution completely independent of Ubuntu).
