Think again if you need that. Things start getting pretty
ugly. :)
Yes, it is not at all intuitive.
Indeed... Sparsh, any reason you need the calculation to be
done on 2d
blocks instead of independent slots?
For my problem, original answer was fine, since parallel
calculations are not at all dependent on each others.
Sometime there are calculations to be done on 2d grid, where
calculations are not uniform across the grid(see paper "An
overview of parallel visualisation methods for Mandelbrot and
Julia sets" where you can see Julia sets parallelization), and
hence, dividing in a particular way leads to better
load-balancing than others.
Thanks a lot for your answer and time.
