Hi I have been using "Platform LSF" compute clusters at work. http://www.hpccommunity.org/section/lsf-11/ Has anyone else here used this system? How about other "compute server" systems? What are other corporations using? I also have heard of "Iron Grid", an open source project, but a quick google did not find it. Rob -- Rob Echlin, B.
