[Mauiusers] 1 CPU jobs

[Leandro]

Sorry for the cross post and for not searching for that on the lists
archives, but I'm really in trouble....

I have some clusters with 2 or 4 cores per node and for some applications,
which uses OpenMP, I need only to allocate 1 core per node to run and the
application forks to the other cores.

With my current configuration, it works for one job. But, when a second job
for the same application is submitted, Torque/Maui allocate the same nodes
to this job, because there are free CPUs on this nodes!

But, as the process forks and runs on all CPUs, what I need is mark the
nodes as used when the nodes have a job allocated to them. It was working
this way when I was using FIFO as the scheduler, but with maui, this
behavior changed.

In Maui, I'm using the parameter "JOBNODEMATCHPOLICY    EXACTNODE" to get it
more close to what is described on qsub command line. In this case, I tried
with qsub -l nodes=X:ppn=1 and -l nodes=X,tpn=1 and none give me the results
I need. I know maui interprets this commands on his own way, but maybe
there's a clean way to do that....

If someone could point me to the right direction, will be great.

Thanks everyone,
