Make sure the .so symlink for the pmix lib is available -- not just the
versioned .so, e.g. .so.2. Slurm requires that .so symlink. Some distros
split packages into base/devel, so you may need to install a pmix-devel
package, if available, in order to add the .so symlink (which is considered a
"development" file).

Thanks Andy,
Slurm was compiled with --with-pmix=/share/local/pmix-3.2.1. The build of pmix
is installed under /share/local/pmix-3.2.1 which is an NFS share across all the
nodes. I should also note I used devtoolset-10 (gcc 10) on RHEL7 and confirmed
that everything was compiled with that version of compiler.
I also set LD_LIBRARY_PATH to include /share/local/pmix-3.2.1
Cheers!
Phil

Also, Slurm was built with "/fs/local/pmix-3.2.1" -- does that translate well
to "/share/local/pmix-3.2.1"?

Hi everyone,
I’ve been having difficulty getting the --mpi=pmix_v3 option to work for me. I
can get --mpi=pmi2 to work ok, but I really want to understand what I’m doing
wrong here. Everything seems to build ok.
