Program PWSCF v.4.1CVS starts ...
Today is 6Mar2009 at 23: 1:23
!!! EXPERIMENTAL VERSION WITH EXX STUFF !!!
!!! DO NOT USE IT FOR ANY PRODUCTION RUN !!!
For Norm-Conserving or Ultrasoft (Vanderbilt) Pseudopotentials or PAW
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
!!! XC functional enforced from input :
Exchange-correlation = PBE0 (6484)
!!! Any further DFT definition will be discarded
!!! Please, verify this is what you really want !
gamma-point specific algorithms are used
tcpu = 0.1 self-consistency for image 0
