AA> Could you try my two trivial benchmarks I sent on lkml too?
I just got around to running your numa01 test on mainline, autonuma, and numasched. This is on a 2-socket, 6-cores-per-socket, 2-threads-per-core machine, with your test configured to run 24 threads. I also ran Peter's modified stream_d on all three as well, with 24 instances in parallel. I know it's already been pointed out that it's not the ideal or end-all benchmark, but I figured it was still worthwhile to see if the trend continued.
On your numa01 test:
Autonuma is 22% faster than mainline Numasched is 42% faster than mainline
On Peter's modified stream_d test:
Autonuma is 35% *slower* than mainline Numasched is 55% faster than mainline
I know that the "real" performance guys here are going to be posting some numbers from more interesting benchmarks soon, but since nobody had answered Andrea's question, I figured I'd do it.
