It is one of those forehead slapping days again, d'oh
Previously on this sc did not have to use the mpi on the end, but now
you do. Problem solved, I think.
<slap>Yep </slap>
Log file now has nnodes: 2 and there is all the domain decomposition
details. That is more like it :)

I get one line like the following for each core in an mpi job:

mdrun_mpi -deffnm ./md5_running/s6117B2_md5 -cpt 600

And you mean mdrun_mpi right?
Chris.
-- original message --
I must be missing something here. Now we don't need to use the -np
switch for grompp or mdrun, you simply specify with mpirun (4.0.3) eg
mpirun -np 4 mdrun -deffnm md_01
Doing that I end up with four separate processes. Does that mean
that the mdrun being used is not mpi enabled?
This is on a super computer system not compiled by myself.
Catch ya,
