[slurm-users] Automatically setting OMP_NUM_THREADS=SLURM_CPUS_PER_TASK?

[Martin Cuma]

Ryan,

we set OMP_NUM_THREADS=1 in the R and Python modules (MKL will honor 
that), and instruct those users that want to run multi-threaded to set 
OMP_NUM_THREADS themselves after loading the module - and make sure they 
don't oversubscribe the node.

In our experience majority of R and Python users run independent serial 
calculations so the default OMP_NUM_THREADS=1 is reasonable.
