Re: P50 - turn-off hyperthreading

Is it possible to turn-off hyperthreading? I want to dedicate at least one core to single threaded task.

Re: P50 - turn-off hyperthreading

have you tried this on P50? Some othee machines, though they do allow entering and adjusting a few parameters in BIOS, do not allow access to hyperthreading option. Thanks!

Yes, I tried it. After changing the setting to 'disabled', the operating system (Linux) showed only 4 CPUs instead of 8.
