I think that's a pretty accurate summary. You just end up with a heap of processes fighting over the same core(s) they are constrained to and polluting each others cache. I would have thought that should have minimal impact on other processes on the node constrained to different cores. Good luck! Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC
