I don't know if it would be enough to hide the problems that led to the JVM crashing on me for the latest version of numacore or not. > THP off: manual placement result: 125239 > > Auto result Man/Auto Mainline/Auto Variance > mainline : 93945 0.750 1.000 5.91% > autonuma : 123651 0.987 1.316 5.15% > balancenuma : 97327 0.777 1.036 5.19% > numacore : 123009 0.982 1.309 5.73% > > > THP on: manual placement result: 143170 > > Auto result Auto/Manual Auto/Mainline Variance > mainline : 104462 0.730 1.000 8.47% > autonuma : 137363 0.959 1.315 5.81% > balancenuma : 112183 0.784 1.074 11.58% > numacore : 142728 0.997 1.366 2.94% > > So autonuma and numacore are basically on the same page, with a slight > advantage for numacore in the THP enabled case. balancenuma is closer > to mainline than to autonuma/numacore. > I would expect balancenuma to be closer to mainline than autonuma, whatever about numacore which I get mixed results for. balancenumas objective was not to be the best, it was meant to be a baseline that either autonuma or numacore could compete based on scheduler policies for while the MM portions would be common to either. If I thought otherwise I would have spent the last 2 weeks working on the scheduler aspects which would have been generally unhelpful. -- Mel Gorman SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
