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?

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,

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`,

Maybe we run into some kind of timeout?

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

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?

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

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

Hi, I would like to announce a new set of LNT -O3 performance testers. In a discussion titled "Question about results reliability in LNT infrustructure" Anton suggested that one way to get statistically reliable test results from the LNT infrastructure is to use a larger sample size (5-10) as well as a more robust statistical test (Wilcoxon/Mann-Whitney). Another requirement to

I will take a peek at the server log.

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.

Hi Daniel, Recently quite a few nice improvements have been made to the LNT webui, and it would be good to have these improvements show up on the instance at http://llvm.org/perf. AFAIK, you're one of the few people who know how to update & restart that instance safely? If so could you update that instance to latest top-of-trunk LNT? I'm expecting more improvements to be done

This was part of the motivation my cloud LNT instance. The Heroku cloud which I am running on is using a postgres cluster, not a single machine. It is well tuned for large databases. > On Nov 30, 2014, at 6:59 AM, Renato Golin <renato.golin at linaro.org> wrote: > > On 30 November 2014 at 13:29, Tobias Grosser <tobias at grosser.es> wrote: >> Proving
