Hi folks: I had been working on integrating mpiBLAST into various environments for a number of customers recently. After completing this work, I began playing with the SGE mpich environment for another customer code. Some things clicked, and I developed a simple shell script to run mpiBLAST through the SGE mpich environment. You can find it at http://scalableinformatics.com/downloads/sge_mpiblast, and the writeup is at http://scalableinformatics.com/sge_mpiblast.html . This isn't terribly fancy, but it worked well for me. I have since integrated the basic ideas into other customer environments with success.
