Renato, Actually I wanted to send GSOC email about the open projects tonight. So, yes - please add them to the corresponding ideas pages.

Ok, I've added the LNT statistics project, I think it's better to add the Clang stuff to http://clang.llvm.org/OpenProjects.html right? cheers, --renato On 27 February 2013 20:17, Anton Korobeynikov <anton at korobeynikov.info>wrote: > Renato, > > Actually I wanted to send GSOC email about the open projects tonight. > So, yes - please add them to the corresponding

Here's another project idea: We really have needed a `clang-config` for a long time; it's absence makes building programs depending on Clang a pain. -- Sean Silva

Daniel, Tobias, Renato and myself have been looking a little bit at the potential underlying reason for why http://llvm.org/perf/ is instable, and have found some clues. I want to share them here to give people with more experience in the frameworks used by LNT (flask, sqlalchemy, wsgi, .) a chance to check if our reasoning below seems plausible. Daniel noticed the following backtrace in the

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,

All, I'm curious to know if anyone is interested in tracking performance (compile-time and/or execution-time) from a community perspective? This is a much loftier goal then just supporting build bots. If so, I'd be happy to propose a BOF at the upcoming Dev Meeting. Chad

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

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, I have recently moved the clang-native-arm-lnt-perf bot from the nt producer to the test-suite producer. It seems to be working fine but it doesn't manage to submit the results to http://lnt.llvm.org/submitRun. If you scroll down to the bottom of [1], you can see this error message: 2017-08-28 07:06:32: submitting result to 'http://lnt.llvm.org/submitRun' error: lnt server:

Great, good to know it's not just a problem with our bot. Thanks!

It is something about how MySQL treats character encodings differently than Postgres. We are checking for the value in the table beforehand, and this

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 James/Chris, You guys have done this before, so I'm guessing you can help me understand what's going on. If my buildbot config is: jobs=2, nt_flags=['--cflag', '-mcpu=cortex-a15', '--use-perf', '--threads=1', '--build-threads=4'] It uses -j4 for build, -j2 for running the tests:

Actually I just remember LNT has a page for viewing the log: http://lnt.llvm.org/log ...

Hi, I've lately been wondering where benchmarks for LLVM-generated binaries are hosted, and whether they're tracked over time. I'm asking because I'm thinking of where to put some benchmarks I've written using the open source Google benchmarking library [0] to test certain costs of XRay-instrumented binaries, the XRay runtime, and other related measurements (effect of

Another suggestion: a web service that would allow you to submit a test build and it would provide you feedback on deviations from known good for that target. I know a lot of people keep two trees around for this purpose, and I'd personally like to ditch the duplicate if I could. -- Chris On Mar 21, 2008, at 9:22 PM, Rajika Kumarasiri wrote: > Hello every body, > Thank you all
