Can anyone tell me how much system overhead is incurred when running in a cluster as opposed to a non-cluster system? I have a 4mb 780 that is going to be clustered soon and people are starting to ask me about it. Thanks, Mike Iglesias University of California, Irvine

Dear Mike: Its not as simple as DEC makes it sound in the cluster literature. Many beings have told me that they have built a clustered system and jobs ran actually slower due to a non optimized cluster. From what I understand about clustering (which isnt much), one needs to hone everything on the cluster to a fine edge inorder to realize any performance gains. "What the "tweakable" variable are exactly and just how to tweak them is a job only a "DEC cluster consultant" can tell us", I am told. Good luck!!! Sincerely, Mitchell
