Yes.

I tried some really simple code like:

use mpi

integer ierr

call mpi_init(ierr)

The problem still exists.

However, I am running the code from some make file and call

the compiler mpif90. Perhaps some special library should be included?

Could the problem be from the hybrid parallelization?

And something else which I am thinking of: Can extra flags for compiler make this happen?

The last question came to my mind because when I try this simple example with mpif90 alone (without make file), it works good.

$(MPIFC) -c $(FFLAGS) $(PFLAGS) $< -o $@

This *usually* means that you are calling the subroutine incorrectly (MPI_Init, in this case). The prototype for MPI_Init is:

subroutine MPI_Init(ierr)
integer, intent(out) :: ierr
end subroutine MPI_Init

Are you passing a writable integer parameter?
