Yes, that's one of the N I had in mind; others provide Linux modules. >From a system manager's point of view it's not clear what are the implications of the unprivileged access, or even how much it really helps. I've seen enough setups suggested for HPC systems in areas I understand (and used by vendors) which allow privilege escalation more or less trivially, maybe without any real operational advantage. If it's clearly safe and helpful then great, but I couldn't assess that. _______________________________________________ users mailing list users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/users
