Hi Paul, Will running your application with taskset or numactl suffice, eg: taskset -c 0-35 cmd or numactl -C 0-35 cmd? Thus pinning the application to the first hardware thread on each core. If not how long do you think you'll need a machine with HT disabled? Ben

Hi,

I'm currently doing some studies on the impact of hardware threading on code performance for nuclear reactor neutronic calculations. I was wondering if it might be possible to have one of the thing nodes configured with hardware threading disabled for the sake of running comparisons.

Thanks, Paul
