Program PWSCF v.6.0 (svn rev. 13188) starts on 6Dec2016 at 17:41:55
This program is part of the open-source Quantum ESPRESSO suite
for quantum simulation of materials; please cite
"P. Giannozzi et al., J. Phys.:Condens. Matter 21 395502 (2009);
URL http://www.quantum-espresso.org",
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 = GAUPBE ( 1 4 20 4 0 0)
EXX-fraction = 0.24
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
