     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


     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
