[slurm-users] Automatically setting OMP_NUM_THREADS=SLURM_CPUS_PER_TASK?

[Martin Cuma]

MKL is trying to be flexible as it has different potential levels of 
parallelism inside. Having MKL_ and OMP_NUM_THREADS can be beneficial in 
programs where you may want to use your own OpenMP but restrict MKL's or 
vice versa.

A good article on the different options that MKL provides is here:

Official Intel guide is here:
