Sorry about the repost, made a quality goof up while typing, so resending
the code snippet. The matrix also looks correct when I o/p it, so not sure
where exactly I am messing things up!

for eg for 2*2*2 grid points :

   Processor    Row Index    Col Index           Value
       0             0             1                      -1
       0             0             2                      -1
       0             0             4                      -1
       0             0             0                       6
       0             1             0                      -1
       0             1             3                      -1
       0             1             5                      -1
       0             1             1                       6
       0             2             3                      -1
       0             2             0                      -1
       0             2             6                      -1
