Kevin Blanchard's Biotechnology Blog: Received from the mpiBLAST team

Received from the mpiBLAST team

mpiBLAST 1.3.0 has (finally) been released. It incorporates several major
design changes that improve reliablilty, performance, and accuracy.

Key enhancements are:
- utilizes latest NCBI Toolbox (Oct 20, 2004)
- E-value scores are exact and identical to scores reported by NCBI
BLAST by using both the effective query and effective database lengths.
(It is necessary/required to patch the NCBI Toolbox before compilation)
- Database pipelining speeds up database distribution by limiting access
to shared filesystem. Number of concurrent accesses is a run-time option
- Results pipelining reduces memory requirements for large query sets.
- Database distribution can occur through cp, scp, or rcp system
calls, through MPI function calls (MPI_Send/MPI_Recv), or not at all if you
choose to use the shared filesystem as local storage. It is a runtime
option (--copy-via).

mpiBLAST version 1.3.0 was a long time in coming, but is the fastest,
most exact, and most stable version of mpiBLAST yet.
