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.

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.

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 all, The LLVM benchmarking system produces very noisy results even on quiet machines. One of the sources of inaccuracy is the timing tool we are using. Because it is a user-space tool, the OS can context switch it and we will get an outlier result. Perf stat uses SW_TASK_CLOCK counter in kernel to measure time, therefore more accurate. It also does not get context switched. I've

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`,

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

The LNT Perf reporting website is down for a few days now, should I disable my perf bot to avoid noise while that gets fixed? cheers, --renato
