mpiBLAST: Open-Source Parallel BLAST

mpiBLAST Releases

Downloads in this area include all bug fixes available. Users who should probably use this version are:

• New users
• Users with production environments
• Users who just want mpiBLAST to work

NEW: mpiBLAST-1.6.0 is now available for beta testing.

mpiBLAST-1.6.0-Beta1

mpiBLAST-1.6.0 is our major effort in enabling users to tackle grand sequence alignment problems on state-of-the-art massively parallel computers. It is now available for beta testing.

Short list of features:

• Adopted a hierarchical scheduling architecture that signifcantly improves program scalability on massively parallel computers.
• Updated NCBI BLAST support to a more recent version (2.2.20, released April 2009)
• Resolved the performance issues when searching large query files.
• Integrated support of IBM Blue Gene/L and Blue Gene/P systems.

mpiBLAST-1.5.0-PIO

mpiBLAST-1.5.0-PIO is the current stable release.

Short list of features:

• Uses serial I/O (e.g. NFS) or parallel I/O (e.g. PVFS) with runtime option
• Able to efficiently and in parallel generate exact e-value scores for large queries
• Scalable database pre-distribution saves time sending fragments to workers
• Efficient caching of database fragments in memory
• Already patched NCBI toolbox eliminates need to download and install separately

See the README file inside the package for a list of run-time and configure options to get the best performance out of mpiBLAST.
