Why don't you use the command "mpirun" to run your mpi programm ?

Yes, I checked that. All files should be closed. I've also written a
small test program,
which is attached below. The output refers to openmpi-1.5.3 with
threading support,
compiled with gcc.
I also tried to use Intel Fortran instead of gfortran and a similar
test program written in C,
compiled with gcc or Intel C. However, the result is always the same.
