KPAR
KPAR = [integer]
Default: KPAR = 1
Description: KPAR is the number of k-points that are to be treated in parallel.
The set of k-points is distributed over KPAR groups of compute cores, in a round-robin fashion. This means that a group of N=(# of cores/KPAR) compute cores together work on an individual k-point (choose KPAR such that it is an integer divisor of the total number of cores). Within this group of N cores that share the work on an individual k-point, the usual parallelism over bands and/or plane wave coefficients applies (as set by means of the NCORE and NPAR tags).
Note: the data is not distributed additionally over k-points.
