Hi, to all.

First, thanks Tobias Burnus for the answers.
I read  https://computing.llnl.gov/tutorials/openMP/,but i didn't see it.
Just i can't access to the node, i.e. i no have jobs running.
For the next time i will read the gcc documentation.

Thanks Tim Prince, for redirecting my mail.
>how did it do with taskset or GOMP_OMP_AFFINITY settings, perhaps with a more up to date libgomp?
i don't use GOMP_OMP_AFFINITY settings. i can't update libgomp.
i don't try use taskset sorry, be couse the multithreading was off.
>Do you have another job running?

of the results).

Regards!
