Hi, SuSE Linux will provide SGE 5.3 (in RPMs) http://www.suse.com/us/press/press_releases/archive02/sun_grid_engine.html FYI, Sun provides a Free on-line training course -- Administering and Supporting SGE -- http://suned.sun.com/US/catalog/courses/WE-1600-90.html SGE is similar to PBS or LSF, but - it has much more features than PBS - it is free, and opensource, and supports many OSes. I first used PBS but found it hard to install, and I found for the price of 1 LSF license (they charge one license per CPU, and they charge for support), I can buy another 2 boxes!! **But one thing I don't like in SGE is the fault tolerance model -- so I proposed a new one -- http://gridengine.sunsource.net/servlets/ReadMsg?msgId=4316&listName=users Lastly, I am new to bio clusters. I am now an SGE admin (contract based) in East Asia. I am starting to study the issues in bio clusters -- forget me if I made too much mistakes in this email!
