The mpiBLAST team announces the availability of mpiBLAST 1.4.0 mpiBLAST 1.4.0 contains several critical enhancements to mpiBLAST's performance, scalability, and stability. This release attained a 305x speedup searching the nt database with 128 worker CPUs. The previous fastest mpiBLAST release gives only 180x speedup on the same data set. Other improvements include result ordering that matches NCBI's blastall and a variety of bugfixes to features like database updating and database removal. We are also pleased to announce that the mpiBLAST web site has migrated to a new wiki-based platform at http://mpiblast.org. The new site fuses information that was previously scattered across several sites. Parts of the site are directly editable using the PmWiki language. Downloads of mpiBLAST 1.4.0 are available here: http://mpiblast.org/pmwiki/pmwiki.php?n=Downloads.Stable Installation instructions are here: http://www.mpiblast.org/pmwiki/pmwiki.php?n=Docs.Install And a more complete list of changes in 1.4.0 is here: http://www.mpiblast.org/pmwiki/pmwiki.php?n=Downloads.Version-History On behalf of our development team, I would like to personally thank everybody who contributed code and submitted bug reports for this release. Several new features in the mpiBLAST 1.4.0 release are based entirely on your feedback and code contributions. --The mpiBLAST Team
