Abstract: Pairwise sequence alignment is often used to reveal similarities between sequences, locate patterns of conservation, study gene regulation, and infer evolutionary relationships [1]. Although the Smith–Waterman is the only algorithm guaranteed to find the optimal local alignment, it is also the slowest one as it costs O(mn) for computation & space. Also the volume of biological data is doubling about every six months so the total cost is O(kmn) where k is the size of the database [2, 3]. By using parallel hardware and software architecture accurate results can be achieved in reasonable time. In this paper we show a comparative study for parallelizing smith-waterman algorithm using different parallel models, pure MPI, pure OpenMP and hybrid MPI/OpenMP model. Based on the results it will be proved that hybrid programming which employ the coarse grain and fine grain parallelization, is more efficient compared with pure MPI and pure OpenMP.
