The Gridengine topology-aware scheduling sounds great, and as you say with multi-core architectures will be more and more useful. I'd like to mention cpuset support though - cpusets are of course vitally useful, however you can have situations where a topology-aware scheduler would allow you to allocate high core count jobs on a machine, using cores which are physically close to each other, yet also run small core count yet high memory jobs which access the memory of those cores.
