Hi Micah > On my machine (2-way Opteron with a vanilla 2.6.23.1 kernel) this test > program will reliably put the scheduler into a state where one CPU has > both of the busy-looping processes in its runqueue, and the other CPU > is usually idle. The usually-idle CPU will have a very high cpu_load, > as reported by /proc/sched_debug. I tried your program on my machine (C2D, 2.6.17, O(1) scheduler). Both CPUs are 100% busy all the time. Each busy-looping thread is running on its own CPU. I've been watching top output for 10 minutes, the spreading is stable and the threads don't bounce at all. greetings Cyrus - 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/ | ||||||||||||
