Hi Sam, This sounds like a Fedora OpenMPI misconfiguration. I guess on the computer that you see no output with relax, you would also see no output with: [edward@localhost ~]$ mpirun -np 5 echo "hello" hello hello hello hello hello [edward@localhost ~]$ In any case, this has nothing to do with relax. And without a local login to your computer, there is not much anyone can do about it. Do you have a system administrator there who can help you? Oh, another good and quick test is: [edward@localhost ~]$ mpirun -np 5 /data/relax/tags/4.0.2/relax --multi="mpi4py" -v relax 4.0.2 [edward@localhost ~]$ You should only see a single version number printed. This tests both your OpenMPI configuration and the mpi4py Python package. If you do not see these exact same results, you have some configuration work in front of you ;) Regards, Edward _______________________________________________ relax (http://www.nmr-relax.com) This is the relax-users mailing list relax-users@gna.org To unsubscribe from this list, get a password reminder, or change your subscription options, visit the list information page at https://mail.gna.org/listinfo/relax-users
