Date: Thu, 18 Jan 2001 15:53:11 -0800 From: Mike Kravetz <mkravetz@sequent.com> To: lse-tech@lists.sourceforge.net Subject: multi-queue scheduler update I just posted an updated version of the multi-queue scheduler for the 2.4.0 kernel. This version also contains support for realtime tasks. The patch can be found at: http://lse.sourceforge.net/scheduling/ Here are some very preliminary numbers from sched_test_yield (which was previously posted to this (lse-tech) list by Bill Hartner). Tests were run on a system with 8 700 MHz Pentium III processors. microseconds/yield # threads 2.2.16-22 2.4 2.4-multi-queue ------------ --------- -------- --------------- 16 18.740 4.603 1.455 32 17.702 5.134 1.456 64 23.300 5.586 1.466 128 47.273 18.812 1.480 256 105.701 71.147 1.517 512 FRC 143.500 1.661 1024 FRC 196.425 6.166 2048 FRC FRC 23.291 4096 FRC FRC 47.117 *FRC = failed to reach confidence level -- Mike Kravetz mkravetz@sequent.com IBM Linux Technology Center 15450 SW Koll Parkway Beaverton, OR 97006-6063 (503)578-3494 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
