Maui Version: 3.2.6p21
Torque Version: 2.3.6
I have a cluster with 4 compute nodes. 1 node has 16 cores and the other 3
each have 24 cores. One of the nodes is down for maintenance. So I have 64
cores available to run jobs.
When I submit this line
qsub -I -l nodes=4:ppn=6
I get the following error:
01/27 13:41:39 INFO: 64 feasible tasks found for job 384:0 in
partition DEFAULT (24 Needed)
01/27 13:41:39 INFO: inadequate feasible nodes found for job 384:0 in
partition DEFAULT (3 < 4)

01/27 13:41:39 MJobSetHold(384,16,1:00:00,NoResources,cannot create
reservation for job '384' (intital reservation attempt)
If I submit this line
qsub -I -l nodes=3:ppn=8
it works just fine

My maui.cfg file has the following variables set.
BACKFILLPOLICY FIRSTFIT
RESERVATIONPOLICY CURRENTHIGHEST
NODEACCESSPOLICY SHARED
NODEALLOCATIONPOLICY FIRSTFIT
ENABLEMULTIREQJOBS TRUE
I am I missing something. Is there a way for maui to schedule the job
since there is clearly enough space to run the job if it schedules 2 of
requests on one node.
Thanks,
