Re: [Question #679153]: About batch mode
Question #679153 on Yade changed:
Chareyre proposed the following answer:
You need to assign openmp threads to each job if you want them to run in
parallel, by default they take one core each. See batch example for details.
I doubt running 4x3 cores will be very fast though. The OS needs something
to run itself, and there are hardware limitations to.
