mpiBLAST 1.3 is now available.

Sunday, December 12th, 2004

Much awaited version of mpiBLAST has been released. mpiBLAST 1.3 is a parallelization of NCBI BLAST. mpiBLAST is a pair of programs that replace formatdb and blastall with versions that execute BLAST jobs in parallel on a cluster of computers with MPI installed. There are two primary advantages to using mpiBLAST versus traditional BLAST. First, mpiBLAST splits the database across each node in the cluster.Because each node’s segment of the database is smaller it can usually reside in the buffer-cache, yielding a significant speedup due to the elimination of disk I/O. Second, it allows BLAST users to take advantage of efficient, low-cost Beowulf clusters because interprocessor communication demands are low.. The current release runs under Linux and Windows, and will probably work on other varieties of Unix as well. mpiBLAST is licensed to the public under the terms of the GPL.
