Have you set the env. variables

OMP_NUM_THREADS

and

GOTO_NUM_THREADS

to 1?

Edo, I didn't do anything about this 2 env variables. Do they need to be set in the submit script, in compiling step, or in .bash_profile? Also, the no. of thread to be set needs to be the same as the no. of cores used to run a job, right?

Thank you,
