[mpich-discuss] How to determine if a program is not started with mpiexec

[Jonathan Bishop]

Hi,

I would like to be able to detect when a program is not started with
mpiexec. This is to prevent MPI_Comm_spawn from failing.

Or is there a way to make MPI_Comm_spawn work in the case where a program is
simply run by running its exec?
