Hi, I've configured our cluster so it uses Simple equal user sharetree policy (http://www.gridengine.info/2006/01/17/simple-equal-user-sharetree-policy/) : >From sge_sched_conf: halftime When executing under a share based policy, the scheduler "ages" (i.e. decreases) usage to implement a sliding window for achieving the share entitle- ments as defined by the share tree. The halftime defines the time interval in which accumulated usage will have been decayed to half its original value. Valid values are specified in hours or according to the time format as specified in queue_conf(5). If the value is set to 0, the usage is not decayed. So, It reduces the impact accrued resource consumptions over the time. the example shows 1000 units and halflife of 7 days: 500 after 7 days 250 after 14 days 125 after 21 days 62.5 after 28 days But, how many "time windows" does it take in consideration? 5? is it configurable? this "divided by 2" is modificable? how to see users resources usage in time per time window? I've configured (using qconf): usage_weight_list cpu=1.000000,mem=1.000000,io=0.000000 but when I open qmon->Policy->Share tree policy->botom-right arrow I see "Share tree policy parameters" (CPU,MEM,IO) all at 33%. Isn't both configurations the same? if yes, why qmon is not showing what I've configured?
