Hi, We have a small cluster (24 CPU) running OpenPBS on suse Linux 8.0. We are experiencing the following problems when submitting jobs with no d= elay=20 (or less than 3 seconds delay) between each submission the system become=20 unstable: sometimes pbs_sched crash with out any note in it's log file. stdout and stderr files goes to the $HOME directory (and not to the=20 ~/.pbs_spool). Should we switch to the PBSPro version? We also need a "swap out Queue", hence low priority queue that will suspe= nd=20 running jobs (and swap them out to the disk) incase some jobs in other qu= eues=20 needs it's cpu. Does such feature exist under PBS system? Thanks. --=20 Ami Klein, System Administrator Division of Genetics Institute of Animal Science and Animal Health The Royal Veterinary and Agricultural University Email: ami@genome.kvl.dk
