[torqueusers] 8-core node "busy" with only 3 jobs

[Jacques Foury]

Hi.

I've just added a quad-opteron dual-core to my cluster.

I added that line to nodes file :

callas99 np=8 opteron

and re-launched pbs_server.

Users submitted jobs, but when reaching 3 jobs on the node, remaining 
jobs are Queued and don't run :


# pbsnodes -a callas99
callas99
     state = busy
     np = 8
     properties = opteron,callas
     ntype = cluster
     jobs = 0/10994.ulmo.math.u-bordeaux1.fr, 
1/10995.ulmo.math.u-bordeaux1.fr, 2/10996.ulmo.math.u-bordeaux1.fr
     status = opsys=linux,uname=Linux callas99 2.6.12-12mdksmp #1 SMP 
Fri Sep 9 17:20:34 CEST 2005 x86_64,sessions=17408 17523 
17536,nsessions=3,nusers=1,idletime=1200524,totmem=33006508kb,availmem=32791272kb,physmem=32802532kb,ncpus=8,loadave=3.00,netload=2486994073,state=busy,jobs=10994.ulmo.math.u-bordeaux1.fr 
10995.ulmo.math.u-bordeaux1.fr 
10996.ulmo.math.u-bordeaux1.fr,rectime=1160044144


Why is this node tagged "busy" with only 3 jobs running ? I particularly 
don't understand that part :

*"ncpus=8,loadave=3.00,netload=2486994073,state=busy"*

If ncpus=8 ad loadave=3.00 it seems to me that state should be free !!!



Maui's checkjob to a queued job says :

job cannot run in partition DEFAULT (idle procs do not meet requirements 
: 0 of 1 procs found)

Why does my np=8 seem not to be taken by the MAUI/Torque system ?

did I forget something ?

Thanks for any help.
