-** MPI version is OpenMPI 4.0.3
-** seems to have problems with InfiniBand module that provoke lots of MPI errors (there's no InfiniBand on belize3)
-** central configuration file /etc/openmpi/openmpi-mca-params.conf has flags set to avoid these problems so you don't have to set any environment variables or command line options to avoid them
