    mpiBLAST 1.3.0 released
    Submitted by Joe Landman; posted on Tuesday, December 14, 2004 (2 comments)
    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 (--concurrent).
    - 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.

    Download it here:

    RPMs of 1.3.0 (source and binary) are available from Scalable Informatics download pages:
