Unable to run legate-boost on multi-node Slurm job (due to be an MPI compatibility?)

[dongb]

The issue is observed when running Legate-boost but looks like a Legate issue in general.
rapidsai/legate-boost#237
Please help to provide a solution.

If we have someone, ideally someone who has experience with Perlmutter would have a look. I hoped @NihaalChowdary was able to run the job since it seemed like an OpenMPI configuration issue that Perlmutter devops may recognize quickly.
