Included with the things you recently tried did you use 'mpirun N mdrun -np 2' in place of
'mpirun -np 2 mdrun -np 2'? I'm certainly no expert, but it is a difference between our scripts.
Otherwise I don't know. Perhaps recompile gromacs. Probably you have looked at
this but did you check
to see that yout .tpr file was created properly? Also you may want to try a
'sleep 10' between
grompp and mdrun in case you have NFS delay issues.
Good luck,
Chris.
### original message
Hi Chris, again ;-)
I'm also running gromacs on another Cluster intel based ( using PBS),
and my script submission procedure is similar to yours!
Now, this new machine I'm trying to use is a SGI 64-way, thus I think
that the lam nodes file is correct: 64 cpu's in a single node, or
something like that. And, as you can see, the "hello" program does work
on this machine when called from mpirun.
As I told in my previous e-mail, there are people using the LAM-MPI on
this machine, and in fact, the hostfile and part of the script
submission file were written by my colleagues. Thus, I think that the
hostfile is correct, and that probably something is not ok with the
submission file, the gmx compilation (though the compilation was
successful) or even with the system configuration.
I tried also the suggestions in your script (exporting PATH,
LD_LIBRARY_PATH, LAMRSH), but getting exactly the same error.
Oh well ...
Thanks for the reply,
Nuno
