alternatively; if a CPU is idle a long time we could do a software level hotunplug on it (after setting it to the lowest possible frequency and power state), and have some sort of thing that keeps track of "spare but unplugged" cpus that can plug cpus back in on demand. That also be nice for all the virtual environments where this could interact with the hypervisor etc ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
