public subroutine Free_DomainDecomposition(this)

Arguments

public subroutine HaloKeySort(keys, elems, sides, flips, ranks, n)

Heap sort of the halo side list by ascending 64-bit key, permuting the companion arrays alongside the keys. O(n log n), in place; the relative order of equal keys is irrelevant because global side ids are unique.
