Hi Ian,

I have 24 physical cores with hyperthreading switched off.

Hi,

And how many CPUs? If you have one CPU with 24 physical cores, then I think you want

ppn = 24

max-num-threads = 24

num-threads = 24

nodes = 1

If you have two CPUs, each with 12 cores, then you probably want

ppn = 24

max-num-threads = 24

num-threads = 12

nodes = 1
