Hi all,

I have created a calendar queue only available during the day (6am to 
1am) keeping nodes free for the night jobs trough an other queue.
This queue is composed of 4 nodes (32cpus). All jobs used the 32cpus

what i don't get is that one of the nodes AND ONLY ONE drop its load 0 
at 1am. this node is the one where the job attributed, i.e.

from qstat
JOB1 xavier       r     10/03/2012 09:44:18 short.q at compute-0-2.local 
     32

while other 3 nodes  keep their load and therefore overload at night.

example of last day load
for compute-0-2

and for compute-0-1
http://nautilus.ciimar.up.pt/ganglia/graph.php?g=load_report&z=large&c=nautilus&h=compute-0-1.local&m=load_one&r=day&s=descending&hc=4&mc=2&st=1349865467

Why does all nodes not behave the same ?
