Indeed. It would appear that one answer is CPU power management groups. These groups would consist of one or more virtual CPUs depending on the hardware capabilities; a single group would be all the virtual CPUs that run at the same power level. Setting the power level on one of the virtual CPUs would affect all the rest in that group. - Bart -- Bart Smaalders Solaris Kernel Performance barts at cyber.eng.sun.com http://blogs.sun.com/barts
