Even if i do not fully understand the question, keep in mind Open MPI does not use OpenMP, so from that point of view, Open MPI is independant of the OpenMP runtime.
Let me emphasize on what Jeff already wrote : use different installs of Open MPI (and you can use modules or lmod in order to choose between them easily) and always use the compilers that were used to build Open MPI. This is mandatory is you use Fortran bindings (use mpi and use mpi_f08), and you'd better keep yourself out of trouble with C/C++ and mpif.h Cheers, Gilles On Tue, Sep 19, 2017 at 5:57 AM, Michael Thomadakis <drmichaelt7...@gmail.com> wrote: > Thanks for the note.
