     Program PWSCF v.6.0 (svn rev. 13188) starts on  6Dec2016 at 17:40: 2 

     This program is part of the open-source Quantum ESPRESSO suite
     for quantum simulation of materials; please cite

     in publications or presentations arising from this work. More details at
     http://www.quantum-espresso.org/quote

     Parallel version (MPI), running on     4 processors
     R & G space division:  proc/nbgrp/npool/nimage =       4
     Waiting for input...
     Reading input from standard input

     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      = PBE0 ( 6  4  8  4 0 0)
     EXX-fraction              =        0.25
     Any further DFT definition will be discarded
     Please, verify this is what you really want


     gamma-point specific algorithms are used
     Message from routine setup :
     BEWARE: nonlinear core correction is not consistent with hybrid XC

     Subspace diagonalization in iterative solution of the eigenvalue problem:
     a serial algorithm will be used

EXX: grid of k+q points same as grid of k-points
