Parallel processing has proven its significant role in various large scale scientific and engineering areas including weather forecasting, air traffic control, petroleum exploration, bio-medical, nuclear energy and defence. Very fast computations of a massive volume of data are an urgent need to support all such real time and real life applications. The computations involved in such applications usually follow some numeric and non-numeric algorithms which are inherently slow to run in a sequential machine. Designing efficient parallel algorithms for such computations have thus been an...
