[Wien] threaded run with SLURM

[Sabry Moustafa]

Hi;


I am trying to run jobs with one node, with multicores, in a threaded 
mode in slurm. I tried to run the serial benchmark problem as given here:

http://susi.theochem.tuwien.ac.at/reg_user/benchmark/

But, did not get difference in CPU time with using any number of cores 
(ntasks-per-node). Here is the most important parts of my serial slurm 
script:

*******

#SBATCH --nodes=1
#SBATCH --ntasks-per-node=4

x lapw1

********

The CPU time should decrease with increasing number of threads as shown 
in the benchmark page above.

So, is just setting "ntasks-per-node=x" makes WIEN2k run in threaded, 
not just serial?


Thanks;

Sabry
