Hi Reuti, William and Gowtham.
So, I set 'slots' for each node which allow our users to benefit the
additional threads or I create a script based on William idea to avoid the
need to reboot all my nodes and turn HT off in the BIOS ?
Both solutions are quite interesting.
Thanks a lot,
Best regar

Setting slots would be the way to go.

Quick answer: No, they're not the same.
Reason: If HT is not disabled but the num_proc or slots is set to half the
available cores, the fake/virtual cores might still be used/assigned for
computation. The result/performance could then depend on whether or not its
corresponding real core is also bu
Hi,
I have many nodes with hyperthreading enable.
I would like to know if modifying the complex value 'num_proc' or 'slots'
to the half of cores is the same thing that to disable the hyperthreading.
If not, what is the difference ?
Thanks,
Best regards,
