Hi Peter, please find the reproducer script attached. My command to reproduce the bug is:
./run-specjvm.sh --benchmarkThreads 32 --iterations 1 --iterationTime 180 --warmuptime 90 xml.transform xml.validation I run just xml benchmarks to speed up the runtime. Please check https://bugzilla.kernel.org/show_bug.cgi?id=120481#c9 for some details how to run the benchmark. The benchmark needs Window manager to be installed to create graphs. However, you can run the script from ssh terminal. I don't know exactly why is that but I know that Python's matplot library has the same requirements. last known good commit: e7904a28f5331c21d17af638cb477c83662e3cb6 first known bad commit: 6ecdd74962f246dfe8750b7bea481a1c0816315d Last two commits to be checked: git log --pretty=oneline e7904a28f5331c21d17af638cb477c83662e3cb6..6ecdd74962f246dfe8750b7bea481a1c0816315d 6ecdd74962f246dfe8750b7bea481a1c0816315d sched/fair: Generalize the load/util averages resolution definition 2159197d66770ec01f75c93fb11dc66df81fd45b sched/core: Enable increased load resolution on 64-bit kernels I use following command to review the results produced by reproduce.sh script. find ./ -name "*log" | xargs grep -H Score | grep xml.validation | grep "[0-9]\{4\}[.][0-9]\{2\} ops/m" Jirka On Wed, Jun 22, 2016 at 9:16 AM, Peter Zijlstra <pet...@infradead.org> wrote: > On Fri, Jun 17, 2016 at 01:04:23AM +0200, Jirka Hladky wrote: >> > > we see performance drop 30-40% for SPECjbb2005 and SPECjvm2008 >> > Blergh, of course I don't have those.. :/ >> >> SPECjvm2008 is publicly available. >> https://www.spec.org/download.html > > Urgh, I _so_ hate java. > > Why does it have to pop up windows split between my screens, total fail. > > In any case, I run it like: > > java -jar SPECjvm2008.jar --benchmarkThreads 40 > > because I have 40 cpus (2 sockets * 10 cores/socket * 2 threads/core). > > It seems to produce numbers, but then ends with a splat: > > Error while creating report: Assistive Technology not found: > org.GNOME.Accessibility.AtkWrapper > java.awt.AWTError: Assistive Technology not found: > org.GNOME.Accessibility.AtkWrapper > at java.awt.Toolkit.loadAssistiveTechnologies(Toolkit.java:807) > at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:886) > at > sun.swing.SwingUtilities2.getSystemMnemonicKeyMask(SwingUtilities2.java:2020) > at > javax.swing.plaf.basic.BasicLookAndFeel.initComponentDefaults(BasicLookAndFeel.java:1158) > at > javax.swing.plaf.metal.MetalLookAndFeel.initComponentDefaults(MetalLookAndFeel.java:431) > at > javax.swing.plaf.basic.BasicLookAndFeel.getDefaults(BasicLookAndFeel.java:148) > at > javax.swing.plaf.metal.MetalLookAndFeel.getDefaults(MetalLookAndFeel.java:1577) > at javax.swing.UIManager.setLookAndFeel(UIManager.java:539) > at javax.swing.UIManager.setLookAndFeel(UIManager.java:579) > at javax.swing.UIManager.initializeDefaultLAF(UIManager.java:1349) > at javax.swing.UIManager.initialize(UIManager.java:1459) > at javax.swing.UIManager.maybeInitialize(UIManager.java:1426) > at javax.swing.UIManager.getDefaults(UIManager.java:659) > at javax.swing.UIManager.getColor(UIManager.java:701) > at org.jfree.chart.JFreeChart.<clinit>(JFreeChart.java:246) > at > org.jfree.chart.ChartFactory.createXYLineChart(ChartFactory.java:1478) > at spec.reporter.BenchmarkChart.<init>(BenchmarkChart.java:47) > at > spec.reporter.ReportGenerator.handleBenchmarkResult(ReportGenerator.java:141) > at > spec.reporter.ReportGenerator.handleBenchmarksResults(ReportGenerator.java:105) > at spec.reporter.ReportGenerator.<init>(ReportGenerator.java:87) > at spec.reporter.ReportGenerator.main2(ReportGenerator.java:750) > at spec.reporter.Reporter.main2(Reporter.java:51) > at spec.harness.Launch.createReport(Launch.java:307) > at spec.harness.Launch.runBenchmarkSuite(Launch.java:250) > at spec.harness.Launch.main(Launch.java:452) > > WTF a benchmark needs that crap is beyond me, but whatever, I have > numbers. > > I'll try and reproduce.
