!
! This is a bit tricky.
! DESC_A is the descriptor of (the columns of) A, and therefore
! of the rows of B; the columns of B, in the intended usage, span
! a different space for which we have DESC_C.
! We are gathering the halo rows of B to multiply by A;
! now, the columns of B would ideally be kept in
! global numbering, so that we can call this repeatedly to accumulate
! the product of multiple operators, and convert to local numbering
! at the last possible moment. However, this would imply calling
! the serial SPSPMM with a matrix B with the GLOBAL number of columns
! and this could be very expensive in memory. The solution is to keep B
! in local numbering, so that only columns really appearing count, but to
! expand the descriptor when gathering the halo, because by performing
! the products we are extending the support of the operator; hence
! this routine is intended to be called with a temporary descriptor
! DESC_C which is in the BUILD state, to allow for such expansion
! across multiple products.
! The caller will at some later point finalize the descriptor DESC_C.
