I can't speak for SGE, but on our LSF cluster, I make the scheduling threshold around the number of processors - 1, and then add a tiny bit. We disable hyperthreading on all of our Intel machines. So, a 2-CPU machine has a scheduling threshold of 1.1; this means it should usually find itself running 2 jobs, but if it's doing anything else at all (cluster filesystem stuff, for example), it tends not to load up a second job. This seems to work pretty well. Tim
