Hi, I see that MPI2.1 says about mpiexec that "If the program named in command does not call MPI_INIT, but instead forks a process that calls MPI_INIT, the results are undefined. Implementations may allow this case to work but are not required to.".
Does OMPI officially support this scenario? Thanks. -------------------------------- Jacob M.
