Detailed Description

Author: Abhinav S Bhatele Date created: March 19th, 2007.

This file makes use of a static table we obtain from a file available on Bigben. Bigben does a XYZT mapping by default. Two steps to obtaining pid2coords and coords2pid are:

1. Get the nid for each pid using the nidpid_map call (also store this information as pid's (two) corresponding to a given nid 2. For each nid in the CrayNeighborTablefile, get the coordinates and assign the corresponding pids in the nid2pid data structure with these coordinates ('t' coord as 0 and 1)
