Detailed Description

Parscalar layout routines.

Layout routines for parscalar implementation QDP data parallel interface

Layout

This routine provides various layouts, including lexicographic 2-checkerboard (even/odd-checkerboarding of sites) 32-style checkerboard (even/odd-checkerboarding of hypercubes)
