Dual CPU i386. $nice -19 ./eatcpu&; $nice -19 ./eatcpu&; $./eatcpu&. IMHO it should be * both niced process run on one cpu. * the non-niced process runs with a 100% timeslice. But it's the other way around: One niced process runs with 100%. The non-niced process with 50%, and the second niced process with 50%. -- Manfred - 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/
