Hi Aaron,
Something happened with the pbs_server, pbs_scheduler or pbs_mom.
We restarted all three and it started working again.
but to answer your question.
#PBS -l walltime=00:10:00
#PBS -l nodes=2:pinecone:ppn=2
It would run a two processor job or a serial job but only on the first
compute node which in this case pc02. The $PBS_NODEFILE with the above
resource request would only have "pc02 pc02" in it.

So jobs aren't running? What syntax are you using to request resources for
submitted jobs?

Hi all,
Ok we installed torque-2.1.9 and had it running on Monday, but now it is
not working correctly. The $PBS_NODEFILE only add has two processors in
it.
The server_priv/node file has
pc02 np=2
pc03 np=2
.
.
pc13 np=2
all the nodes are "free" according to the pbsnodes -a output
pc12
state = free
np = 2
properties = pinecone,v20z,score

I don't think we have changed anything it just quit!!
