I'm guessing you didn't implement the changes as recommended by Jeff Squyres, correct? His response is authoritative. >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" This result, i.e., "node3.cluster.ird.nc" is correct assuming this is the name of one of your compute nodes. Your job is started on one of the compute nodes, with the other nodes available to you (including the job-start node) listed in PBS_NODEFILE=/var/spool/pbs/aux/174.editr.cluster.ird.nc According to the environment display, your job *originated* on PBS_O_HOST=editr.cluster.ird.nc that is, this is the node whence you ran qsub. -- David N.
