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.

Hi,

How do I send enviroment variables to a spawned process spawned using MPI_Comm_spawn. I tried to use MPI_Info, but it doesn't seem to work. Does anyone have a example that I could look at.

Please let me know,

Thanks

Ramesh
