I will take a peek at the server log.

Dear all, I recently started to see internal server errors when submitting perf results to lnt.llvm.org http://lab.llvm.org:8011/builders/perf-x86_64-penryn-O3-polly-before-vectorizer/builds/1154/steps/lnt.nightly-test/logs/stdio nt /home/grosser/buildslave/perf-x86_64-penryn-O3-polly-before-vectorizer/tests/nt/build/sample-0/report.simple.csv

Here a link to the most recent failing results file: http://lab.llvm.org:8011/builders/polly-perf-O3/builds/704/steps/lnt.nightly-test/logs/report.json Please download it as the buildbots will delete it at some point.

Maybe we run into some kind of timeout?

Actually I just remember LNT has a page for viewing the log: http://lnt.llvm.org/log ... OperationalError: (OperationalError) (2006, 'MySQL server has gone away') 'SELECT `NT_Run`.`ID` AS `NT_Run_ID`, `NT_Run`.`MachineID` AS `NT_Run_MachineID`, `NT_Run`.`OrderID` AS `NT_Run_OrderID`, `NT_Run`.`ImportedFrom` AS `NT_Run_ImportedFrom`, `NT_Run`.`StartTime` AS `NT_Run_StartTime`,

The run page problem were triggered by one of my commits (sorry) and should be mitigated now, see the thread at http://lists.llvm.org/pipermail/llvm-dev/2017-July/115971.html <http://lists.llvm.org/pipermail/llvm-dev/2017-July/115971.html> I don't know about the submission problems, could they just an occasional network problem or are they a common phenomenon? Chris did some

Hi, So, I owe you all an apology. I was totally unaware that the llvm.org server, running at UIUC, was still in operation and hosting an active LNT instance. I was under the assumption the LNT server ran elsewhere. As a result, the ability for the LNT bots to submit run information to the "old" LNT server is now gone. I am very sorry for this oversight. In speaking with Chris

Hi, The new LNT server instance http://lnt.llvm.org seems to fail in many cases. Any entrance to a 'Run page' (e.g. http://lnt.llvm.org/db_default/v4/nts/62475) and lately also many perf bots result submissions (e.g. http://lab.llvm.org:8014/builders/clang-native-arm-lnt-perf/builds/2262/steps/test-suite/logs/stdio ) fails with: "500 Internal Server Error". Any ideas? Thanks,

I don’t have access to that server. I have been using a cloud LNT instance for the performance runs on the green-dragon cluster. So far it has provided 100% uptime! http://llvm-lnt.herokuapp.com <http://llvm-lnt.herokuapp.com/> > On Nov 24, 2014, at 3:24 PM, Tobias Grosser <tobias at grosser.es> wrote: > > On 24.11.2014 23:54, Galina Kistanova wrote: >> Hello

Hi, I am currently investigating how to ensure that LNT only shows relevant performance regressions for the -O3 performance tests I am running. One question that came up here is why the default aggregate function for LNT is 'min' instead of 'mean'. This looks a little surprising from the statistical point, but also from looking at my test results picking 'min' seems

Right - you usually won't see a normal distribution in the noise of test results. You'll see results clustered around the lower bound with a long tail of slower and slower results. Depending on how many samples you do it might be appropriate to take the mean of the best 3, for example - but the general approach of taking the fastest N does have some basis in any case. Not necessarily the

Hi, I have been following the development of the /zorg/trunk/lnt project for a while and am wondering if there is some regular LLVM performance testing using LNT that can be accessed online? Are there any plans to create an officially used web service for this like e.g the llvm buildbots? Thanks a lot Tobi

Hi, I get an internal server error when accessing llvm.org/perf. This error causes buildbot failures as they can not properly report their performance findings. Chris, could you have a look? Thanks, Tobias

I agree that we should add this feature. No point in submitting results that we don’t plan to use.

Hi Chris, llvm.org/perf gives again error 500s. I remember you had a look the last time. Would you mind looking again? Also, is there something which we could do to make LNT more robust. Do you have an idea what the last issue was about?
