[QE-users] "vc-relax" and "relax" with hybrids

Thank You, Paolo and Giusepe

It is really awesome to get response from You :). I will try norm
conserving pseudopotentials.
However, as I understand they are a bit outdated?

Few additional questions if You don't mind:
- Should I expect constrained orbital calculations (delta SCF) work well
with hybrids?
- Any suggestions for hybrid parallelisation? We have shared memory 36 core
mashine with hyperthreading (72 threads).
  System size is 200-500 carbon atoms + defect.

Thanks for Your time,
Lukas
