[Users] load balancing

I was thinking of trying to run Cactus on supermic and attempting to use the mics. I'm not expecting to receive any speedup from doing so, but I'm going to try.

One thing I'm wondering is whether I would receive a speedup if the mic nodes had a different number of gridpoints than the CPUs (again, not overly optimistic). Is there a way to tell a load balancer to give half the nodes a larger share of gridpoints? If there isn't, how hard would it be to create such a load balancer?
