Parallel version (MPI), running on 4 processors
R & G space division: proc/nbgrp/npool/nimage = 4
Waiting for input...
Reading input from standard input
Message from routine read_cards :
DEPRECATED: no units specified in ATOMIC_POSITIONS card

Current dimensions of program PWSCF are:
Max number of different atomic species (ntypx) = 10
Max number of k-points (npk) = 40000
Max angular momentum in pseudopotentials (lmaxx) = 3
IMPORTANT: XC functional enforced from input :
Exchange-correlation = HSE ( 1 4 12 4 0 0)
EXX-fraction = 0.25
Any further DFT definition will be discarded
Please, verify this is what you really want
Subspace diagonalization in iterative solution of the eigenvalue problem:
a serial algorithm will be used
EXX: setup a grid of 256 q-points centered on each k-point
(set verbosity='high' to see the list)
