hi Garrick,
i'm trying your patch on my dual Opteron cluster and
it seems to work. i'm very happy because i plan to use
torque/maui on our IBM SMP cluster (8 cpus per node)
where i would like to request cpus (not nodes=X:ppn=Y)
and let the scheduler choose the nodes.
on the opteron cluster i discoverd that, if i submit
a job with -l ncpus=4, maui creates only one task
(with PROCS=4) and the job will never run because it
cannot find a node (with 4 cpus) to satisfy the task.
it seems a strange behaviour!
anyway, thank you very much. i will give you feed back
as soon as i will try your patch on the IBM.
bye
ale
PS: why did nobody reply you?
