I believe I am running 18.04 on the Z620; though for my use case localhost-only does help, as others have found that using MPI for each socket is much faster than using a single pool of threads. I'm running -t 20 right now on the dual-10-core, where I'd like to be running MPI 2x10-threads.

Good to know it's likely openMPI that I should try to address, rather than my build of msieve.
