Thanks for the information. I would like to set up RPi cluster for some bioinformatics jobs like sequences alignment and sequences operations. And I would use OGS(Open Grid Scheduler) as DRM to manage those nodes. I do know that ARM processors cannot provide powerful FP computing so I'm guessing that would be feasible to do some sequences operations. Pls. point me out if I was wrong. One more thing, I would like to know what field is proper for ARM processors. Thanks. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
