[torqueusers] Do I have to define the ncpus for a compute node?

[Ryan Golhar]

Hi - I have a ROCKS cluster running and installed Torque.  I'm able to
submit 1 core, 1 cpu jobs without problem.  I tried submitting a job that
requested 4 cpus on 1 node using

#PBS -l nodes=1:ppn=4

in my job submission script.  When I submit the job however, I get the
error:

qsub: Job exceeds queue resource limits MSG=cannot locate feasible nodes
(nodes file is empty or requested nodes exceed all systems)

If I run anodes, I see:

compute-0-0
     state = free
     np = 8
     ntype = cluster
     status =
rectime=1326469800,varattr=,jobs=,state=free,netload=1720539412488,gres=,loadave=0.01,ncpus=8,physmem=16431248kb,availmem=17311704kb,totmem=17451364kb,idletime=339141,nusers=0,nsessions=?
15201,sessions=? 15201,uname=Linux compute-0-0.local 2.6.18-238.19.1.el5 #1
SMP Fri Jul 15 07:31:24 EDT 2011 x86_64,opsys=linux
     gpus = 0


All my compute nodes have 8 cpus.  Do I need to tell Torque this?  I
thought Torque could figure this out from np=8 or ncpus=8.
