Lets see what Paul has to say. Unless I'm missing something (a frequent occurrence) such a use of cpusets looses on the understandable, is hobbled on the overcommit, and has to make do with a somewhat oddly limited and not trivial to configure approximation of the dynamic sharing. And the reconfiguration would seem to be a great exercise of memory hotunplug (echos of the original motivation for fake numa - exercising cpusets ;). Not exactly passing with flying colors ;). -- I won't rest till it's the best ...
