Hi Chris, My group is running Sequest on an IBM JS20 cluster (Suse linux). My knowledge of the gory details is not sufficient to really answer your questions, however, I can share my quick thoughts and I believe our SysAdmin (Kent Brodie) is also on the list and will get back to you with more of the real details. Our current configuration has a Windows headnode running 8 dual processor JS20 nodes. Sequest uses PVM for job distribution and once you have it set up it seems to do a decent job with only a few hiccups here and there. We did not look at trying to integrate with LSF or SGE. We prototyped the port of Sequest to the PowerPC architecture in collaboration with IBM and Thermo and so stayed with a vanilla PVM-Sequest system and we currently dont run anything else on the cluster. I see no reason why we cant run other things on there (and that is the plan ultimately), but I dont know enough to speculate about how well PVM and LSF/SGE would play together. We haven't been generating vast quantities of data that we've want to store as we've been mainly developing experimental techniques. However, we're gearing up to start creating more results that we will be keeping over the long term so we would be very interested in chatting more about what we have and what you are thinking. You can find a little more info on our website (proteomics.mcw.edu) but the bioinformatics section is rather out of date and something I now notice I have to fix. There is also an overview of what we are trying to do in the area of proteomics and bioinformatics on the NHLBI Proteomics website, this was an overview presentation I gave a little while back so it doesnt have much detail. http://www.nhlbi-proteomics.org/content/MCW_prest/Twigger.pdf Kent will be able to answer your real questions but lets chat more about how you are working on this as we'd love to share experiences and learn from what you are trying. Cheers, Simon. On Aug 15, 2005, at 11:46 PM, Botka, Christopher wrote: > > Is anyone out there running Sequest on Linux for MS analysis?
