Is O3-vectorize redundant now that the loop vectorizer is enabled by default?

They're just build bots running LNT - check the build bot configuration code in the zorg llvm project repository. You'll probably need to do some work to get a machine quiet enough to have reliable/useful performance results, though

Those running LNT should be/are:

The -vectorize build bots test the BB-vectorizer.

LNT debuginfo-statistics not running?
The debug info statistics bot is triggered by this job: http://green.lab.llvm.org/green/job/clang-stage2-Rthinlto/ which unfortunately hasn't been green in a very long time (>1mo).
Alex/Azhar, do you know what's blocking that job?

LNT debuginfo-statistics not running?
Hi llvm-dev@
LNT produces statistics and graphs (such as [0]) of debuginfo metrics,
such as number of source variables with locations. It looks like these
haven't run [1] since the move from svn to git -- are there any plans
to get these running again? I find it highly useful to identify what
commits have affected variable locations and how significant an
affect.

[LNT] new server instance http://lnt.llvm.org seems unstable
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,

[LLVMdev] Why is the default LNT aggregation function min instead of mean
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

[LLVMdev] Why is the default LNT aggregation function min instead of mean
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 Kristof,
The way we use LNT, we would run different configuration (e.g. -O3 vs -Os) as different "machines" in LNT's model.
O2/O3 is indeed bad example. We're also using different machines for Os/O3 - such parameters apply to all

Benchmarks for LLVM-generated Binaries
Hi Eric,
Yeah, I know about Externals and SPEC specifically. But as far as I understand, you have to have kind of description of the tests in test-suite even if you don’t provide the source codes - that’s what I would like to avoid. I.e. you have to have CMakeLists.txt and other files in place all the time, open to everyone.
Now, imagine I have a small testsuite, which probably is not very

[LLVMdev] New -O3 Performance tester - Use hardware to get reliable numbers
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

LNT Server offline
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.
