Oups ! I got it ... One of my slaves has been compiled with a bad mpif77 (one mpif77 coming with an old Lam installation provided by Portland PGI). So I rectified my Path to have the correct mpif77, and it's much better Sorry for this mistake and thank you for your help Pierre

You say you're running on a cluster, can you do `which mpirun` in the submit script, just before running mpirun and is the result the same? What happens if you do `mpirun --version` in the said script (or node)? (what I intend to say is how are you sure that is not lam mpirun that is being called in that particular node?) best, Ricardo Reis 'Non Serviam' PhD candidate @ Lasef Computational Fluid Dynamics, High Performance Computing, Turbulence http://www.lasef.ist.utl.pt Cultural Instigator @ Rádio Zero http://www.radiozero.pt http://www.flickr.com/photos/rreis/ contacts: gtalk: kyriu...@gmail.com skype: kyriusan < sent with alpine 2.00 >
