Hello

I am trying Torque -3.-0.3.  with numa support. This is my first attempt to
understand numa and torque, so just consider this a newbie question.


I have configured two numa nodes in my mom.layout

*cpus=0-15    mem=0
cpus=15-31   mem=1*


Also this is my server_priv/nodes file

*v2 np=32 num_numa_nodes=2*


So when i run pbsnodes -a  i dont get loadaverage reported by pbs_mom.

* pbsnodes -a
v2-0
     state = free
     np = 16
     ntype = cluster
     status = rectime=1345200884,varattr=,jobs=,state=free,netload=?
0,gres=,loadave=?
0,ncpus=16,physmem=16768036kb,availmem=15385544kb,totmem=16768036kb,idletime=355542,nusers=0,nsessions=0,uname=Linux
v2 2.6.32-71.el6.x86_64 #1 SMP Fri May 20 03:51:51 BST 2011
x86_64,opsys=linux
     mom_service_port = 15002
     mom_manager_port = 15003
     gpus = 0

v2-1
     state = free
     np = 16
     ntype = cluster
     status = rectime=1345200902,varattr=,jobs=,state=free,netload=?
0,gres=,loadave=?
0,ncpus=16,physmem=16777216kb,availmem=16073452kb,totmem=16777216kb,idletime=355542,nusers=0,nsessions=0,uname=Linux
v2 2.6.32-71.el6.x86_64 #1 SMP Fri May 20 03:51:51 BST 2011
x86_64,opsys=linux
     mom_service_port = 15002
     mom_manager_port = 15003
     gpus = 0
*

My question is how can i get this loadaverage information in numa
configuration if it does provide one? How does pbs_sched than changes the
state of node (from busy to free and vice versa ) based on load average?

Thanks
