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.
