Due to exponential growth in the size of genomic databases, traditional techniques of sequence search proved to be slow. To address the above problem, an open source and parallel version of BLAST called mpiBLAST was developed by the programmers. In mpiBLAST, the master process distributes the database fragments among worker nodes to compute the sequence search in parallel. As merging and writing of the results is done sequentially by the master process, it would create performance bottleneck with increasing number of processors and varying database sizes.
