I want to calculate optic properties of ZnO  bulk using quantum
espresso .The papers reported  to need many k-points (50* 50 *31) for
calculation optic properties of ZnO  bulk .I calculate nscf using 27*
27*18  k_point and calculate epsilon.x. But chart is not corresponding
of  other papers  ( using other cods) .
I use 36*36*27 kpoint , but nscf stops on      Computing kpt #: 19459
Pleas guide me
 Thank you
