Hello,

we have a NICE DCV Maschine and started a parallel calculation with starccm+ v9.06.009 with 4 cpus.

The problem is that although 20 cpu cores are available, only one is used.
A session runs within a cgroup with 4 assigned cpus, generated from grid engine.
Is this a configuration issue? How to fix it?
