Subject: Re: [OMPI users] mpirun error with " The MPI_Comm_f2c() function was called before MPI_INIT was invoked."
From: Jeff Squyres (jsquyres_at_[hidden])

More specifically -- are you calling any MPI function before calling MPI_Init? (particularly from Fortran)

I.e., you may be seeing a side-effect of calling a fortran MPI function before calling MPI_Init.
