[gmx-users] lam -mpi problem

[Luciane Vieira de Mello Rigden]

Dear all,


I am trying to run an MD using two processors, linux DELL 650, xeon
processor.

It is a procedure I have already done on other similar machines, and no
problem at all. It seems it is a problem specific for this machine.
------------------------------------------------------------------
[mello at biolinux gromacs_dyn]$ lamboot -v bhost

LAM 6.5.6/MPI 2 C++/ROMIO - University of Notre Dame

Executing hboot on n0 (biolinux.liv.ac.uk - 2 CPUs)...
topology done      

[mello at biolinux gromacs_dyn]$ ps -efl |grep lamd
000 S mello    21078     1  0  77   0    -   446 schedu 11:38 ?       
00:00:00 /usr/bin/lamd -H 138.253.197.47 -P 51003 -n 0 -o 0

[mello at biolinux gromacs_dyn]$ mpirun C mdrun_mpi -s topol_2n_biolinux.tpr -v
[mello at biolinux gromacs_dyn]$
------------------------------------------------------------------

In other words, although lamboot looks fine and the lamd process is
running, mpirun stops immediately without generating any output.
The same files were used in a different  twin-xeon Dell machine, and it
was fine.

Thanks in advance,
Luciane
