We are about to start the build out of a 200 node cluster, and we plan to use SGE 6 for job scheduling. The NFS device is an EMC Centera with 3 data movers, so it should shift data at a decent speed, but I don't know about SGE scalability. Question: Is anyone using SGE via NFS on this number of nodes? Has anyone reached a CPU/scheduling limitation on a lesser number of nodes. Would SGE with Berkeley DB be of benefit here? Who would recommend a local install of SGE on each node? Cheers, Steve
