[QE-users] Sub optimal performance on 32 core AMD machine

[Pietro Delugas]

Hi
Are you using hyperthreading ? 
If yes, you should try  to use  only 32 cores.  Check the total number of processors at the beginning of the run. 
The program makes an intense usage of the cpus so that  hyperthreading  is usually inefficient.
