Dear Chris,
Thanks for your reply. I am not an expert on this issue, but from what you said and from:
I can conclude that I should do:
export MKL_NUM_THREADS=1
export NUMEXPR_NUM_THREADS=1
export OMP_NUM_THREADS=1
in the machine that will run my code, in the cluster, before starting the data processing. I will try that and see what happens.
Cheers.
