MpiBLAST
From BioPerl
MPI-BLAST is an open source MPI implementation of BLAST written by Aaron Darling and collaborators. It achieves a speedup that general scales with the number of CPUs used by splitting the database into chunks and only requiring a query to be searched against a portion of the database before combining the results into proper E-values. The E-values were quite inaccurate in previous versions of the program but the methodology has since been improved in the latest (2005+) versions.
