Hello,
I found the answer to this.
Need to use the
JOBNODEMATCHPOLICY Maui parameter.
#####################################
I am using Maui 3.2.6p16 and Torque 2.1.1
I am testing submitting a job to the maui scheduler using an mpirun.
All the nodes on the cluster are dual processor and if you choose:
#PBS -l nodes=<node_count>:ppn=2
in the pbs script everything is fine.
But if I choose just:
#PBS-l nodes=2
(I understand that this is the same as choosing: #PBS-l nodes=2:ppn=10)
It only picks one nodes for the machine file for the mpirun and not two nodes.
(My script uses the $PBS_NODEFILE variable to generate a machine file).
I would have thought in this case it would try to use one processor
on two different nodes?
Any help would be greatly appreciated.
Thanks,
Regards,
Eugene.
