Multics initially had something like that too. http://www.multicians.org/mult-sched.html Anyway that's pretty standard CS stuff. Multi-level Queues with feedback, exponentially longer timeslices with lower priority. I was reading this recently, that's why i wondered why linux calculate timeslice "inversed" versus what is proposed in theory. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
