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
Subspace diagonalization in iterative solution of the eigenvalue problem:
a serial algorithm will be used
EXX: setup a grid of 10 q-points centered on each k-point
