PBS has configured with by_queue and round robin disabled. Users jobs queued as FIFO. But we want to have fairshare policy with the queue so that resources shared. somehow fairshare configuration not working for us. Any suggestions ?
Enabled below into configuration file /opt/pbs/etc/pbs_sched_config
fairshare: true all
restarted services pbs stop and start" after changes to pbs_sched_config
However, don’t see any effect of the fairshare.
[root@hpc etc]# pbsfs
Creating usage database for fairshare.
Fairshare usage units are in: cput
TREEROOT : Grp: -1 cgrp: 0 Shares: -1 Usage: 1 Perc: 100.000%
unknown : Grp: 0 cgrp: 1 Shares: 0 Usage: 1 Perc: 0.000%
