That sounds good to me!

I agree very much with what you say here.
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.
