Hong Zhang, There are several clusters doing Blast and Blast over WWW at Harvard. Contact me in private if you want contact information for the people running them. The Bauer Center for Genomics Research has a big cluster system running Platform LSF. (http://cgr.harvard.edu) The Harvard Stats department over in the Science Center is running Grid Engine on a small Linux cluster. The Flybase project people are using Grid Engine on Mac OS X (apple Xserves) for some lightweight web bioinformatics portal stuff (http://inquiry.flybase.harvard.edu) There are several more systems I've heard about or visited over at the Medical school etc. Regarding your questions: 1. wwwblast servers are easy to set up on clusters. For a lightweight system you can just take the LSF 'lsrun' or Grid Engine 'qrsh' commands and use them to wrap the call to the blastall executable. This will not work in a large setting as qrsh/lsrun will fail silently if there are no resources available; in that case you need to go asynchronous and get used to the batch system. 2. SGE easily runs on Debian linux Regards, Chris Hong Zhang wrote: > Thanks for your information.
