I beleive Pushkar is trying to chunk the image up into pieces for processing on different processors. Perhaps the way to chunk the file up is to use either the tiles or strips. Say there are 5 strips and 2 processors. Then 2 strips go to each processor, and the remaining strip goes to one processor or the other... Ditto for tiles. I remember using MPI to parallelize the LDU decomposition of a matrix. It got to be rather heinous, but I was a math magor, not a comp. sci. magor. :-)
