[mpich-discuss] Question

["Antonio J. Peña"]

In a homogeneous execution all MPI processes should have the same 
environment variables. If that's not your case, maybe you could consider 
just reading it by means of a call to getenv and using MPI 
sends/receives/collectives/one-sided. You can afterwards setenv it if 
that's what you want.
