If you build Open MPI v3.1.2 with gfortran 4.8.3, you will automatically get the "old" implementation of the "mpi" module. I don't recall offhand (because I think we stopped the --with-mpi-f90 option after the v1.6 series), but I think the "mpi" module will be sized "medium" (we took away the ability to pick the size, because the Way Forward is to use a newer compiler). -- Jeff Squyres jsquy...@cisco.com _______________________________________________ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users
