Hi Jeff,
FWIW, environment variables prefixed with "OMPI_" will automatically be
distributed out to processes.
Of course, but saddingly the variable(s) we want to ditribute aren't

Depending on your environment and launcher, your entire environment may
be copied out

The most likely solution would be to specify multiple "-x" equivalents
by separating them with a comma in the
Dear OpenMPI developer,
with the -x option of mpiexec there is a way to distribute environmnet

Is there an environment variable ( OMPI_) with the same
