At first I was running the pwscf v.6.1 that was precompiled on ARCHER and in that case the parallelisation over k-points didn't work when using hybrid functionals. However, it does work with the pwscf version (also v.6.1) I compiled myself.

When I don't use parallelisation over k-points, i.e. when I don't specify npools, the calculation runs successfully. However, as soon as I try to make use of npools, the calculation crashes with: DPOTRF exited with INFO= 7 Error in routine DPOTRF (1): Cholesky failed in aceupdate. I have attached the corresponding output file. Previously I have had the same issue with another compound but in that case npools = 2 actually did work and it only crashed with the above error when npools > 2. So it's not necessarily that the parallelisation with npools doesn't work at all. Not using the ACE algorithm makes the calculation painfully slow so I'd like to avoid that. Do you have any advice on how to optimise the parallelisation of hybrid DFT calculations in general?
