[Pw_forum] Hybrid calculation with ACE in QE v.6.1

[Taylor Barnes]

Hi Mohammed,

   QE version 6.1 contains many changes I made to the EXX implementation in
order to improve the performance of the code when running large
calculations on many nodes.  The calculation you are running is very small
and won't necessarily benefit much from these changes, but it certainly
shouldn't perform worse.  If you send me your input file and pseudos, I'll
see if I can determine what is going on.

Best,
Taylor Barnes
