Hi Folks: We completely rewrote our sge_mpiblast execution tool into a real program that allows you to run the excellent mpiBLAST (http://mpiblast.lanl.gov) code within the SGE queuing system on a bio-cluster. The new code is named run_mpiblast and is available from our download page (http://scalableinformatics.com/downloads/). Documentation is in process, and the source is heavily commented. The principal differences between the old and new versions are . error detection and problem reporting . file staging . rewritten in a real programming language, no more shell script . works within SGE, or from the command line . uses config files . run isolation . debugging and verbosity controls This is a merge between an internal project and the ideas behind the original code. Please give it a try and let us know how it behaves. The link to the information page is http://scalableinformatics.com/sge_mpiblast.html .
