Hi ulrich,

You should use parallel environment (PE). For more information "man sge_pe".
Example : qsub -pe make 48 job.sh

Objet : [gridengine users] CPU allocation

Dear list,

I have installed GE2011.11p1 on an opensuse 12.3 cluster.
I send a job to the cluster that requests, say N CPUs.  When the job
starts running, I am allocated N CPUs.  However the only CPUs that are
actually used are those on the same host as the master process.  I
expect the job would get the N CPUs requested and run on all CPUs
allocated on all hosts.

Does anybody have an idea how I can influece that behaviour?

'qconf -mq all.q` gives the params below.

Please tell me if you need more informations.

With kind regards, ulrich
