I'm not quite sure what you're asking. The openmpi-mca-params.conf does not define environment variables; it only sets values for Open MPI's MCA parameters (i.e., run-time parameters). If you want to pass environment variables from the environment of mpirun to the MPI processes that it starts, use the -x CLI option to mpirun. For example: export FOO=bar mpirun -x FOO --host a,b -np 2 my_mpi_program -- Jeff Squyres jsquy...@cisco.com _______________________________________________ devel mailing list devel@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/devel
