Ok, I make change, but still have sometime 2 nodes instead 4.
If i run a simple script mpihello.pbs, my job run over the 4 nodes.
However, I meet always trouble with our Ocean Model. Even if i keep same PBS variable like test program Mpihello, my job run over 2 nodes instead 4. By hand, lamboot, mpirun, lamhalt, all nodes compute.
Can you tell me about this :
pbs_script include 2 lines : echo My hostname is : $HOSTNAME and echo My environnement: /usr/bin/env
If i qsub my_env.pbs, result is : node3.cluster.ird.nc !!
Why not my hostname "editr.cluster.ird.nc"
This is important to know how to modify this PBS variable, because i.e. if i edit a more complex PBS script, which make file transfert (like CP, MV, RM ...) before to execute the job, and files location is a NFS partition mounted on HOSTNAME = "editr.cluster.ird.nc", then these files are not found. Because after PBS evocation, HOSTNAME is "node3.cluster.ird.nc"
???
Many thanks !!
