Thanks,<br>I found scheduling optimization description at <a href="http://www.clusterresources.com/products/maui/docs/8.2backfill.shtml#algorithm">http://www.clusterresources.com/products/maui/docs/8.2backfill.shtml#algorithm
</a><br><br>By default, backfill is enabled in Maui using the <b>FIRSTFIT</b> algorithm.
However, this parameter can also be set to <b>BESTFIT</b>, <b>GREEDY</b>, or <b>NONE</b> (disabled). <br><br>cheers,<br>Khazret Sapenov,<br>Enomaly Labs,<br>Toronto, Canada<br><br><br><div><span class="gmail_quote">On 8/23/07,

<br> If I remember correctly, there should be a GREEDY scheduling<br>mode that schedules optimally. I always used one of<br>the other modes that scheduled higher priority jobs first.<br>It was a lot easier to monitor what the scheduler was doing.
