Comment #1 on issue 3806 by sebastia...(a)gmail.com: Duration>>hours is broken http://code.google.com/p/pharo/issues/detail?id=3806 deeper than I though... #minutes and #seconds are broken too #asSeconds is doing the #seconds work but the thing should be the other way around (#asSeconds should be synonym of the "#seconds" of the duration) and if for any nerd reason you want the seconds of the last day of the duration then, if the image is generous with that nerdicism, then you should be specific and get it (so #lastDaySeonds should exists)

[Pharo-project] Issue 3806 in pharo: Duration>>hours is broken

by pharo＠googlecode.com

Status: New Owner: ---- New issue 3806 by sebastia...(a)gmail.com: Duration>>hours is broken http://code.google.com/p/pharo/issues/detail?id=3806 Steps to reproduce: 1. self assert: 2 days hours = 48 2. do 3. it it will fail It's a bug because of what is said in the comment. But please don't even think in fixing it by changing the comment. Even a toddler would expect to see 48 hours in a duration of two days. BTW: I've just saw this and I'm probably going to make a patch

Re: [Pharo-project] how I am supposed to load Spy?

by Alexandre Bergel

Kai uses the output of messagetally to obtain method execution time and the coverage. What has been covered is then instrumented for a second run of you code. Note that the Pharo kernel is not instrumented (this is why you have an empty result). Additional metrics are then obtained. So, my advice is to not use a 'hello world' like example. On the class side of KaiProfiler there are some examples. But essentially, where messagetally does not give result then Kai will be of no help. In case where message tally gives some results, then Kai will help you to find bottleneck and will give hints on how to resorb it. I know this is a serious limitation of Kai. As I said, I am working on a new generation of code profilers that are not based on execution sampling. I recently shown that counting messages is as efficient as sampling the execution to identify bottleneck. But message counting has some wonderful properties: it works for very short execution, it is much more stable and it is not subject to the memory management. More will come soon.

But as I said it works like the UnitTest suite, hence there is nothing to run in there. Try one of the actual test-classes like PBString run and you will get a PBenchmarkRun back, as you would with a TestCase. let me know if that helps :). camillo > >> >> >> m(^_-)m >> camillo >> >> On 2011-03-11, at 15:05, Alexandre Bergel wrote: >> >>> I am not sure what you mean with vm benchmarks, but in almost all the >> tools I am contributing come with some benchmarks (spy, Mondrian, I wrote >> some benchmarks for Glamour as well).

Re: [Pharo-project] VM Benchmarks

by Stefan Marr

Hi: I have currently the following benchmarks at hand, partially taken from PharoBenchmarks and partially from the language shootout (http://shootout.alioth.debian.org/, https://alioth.debian.org/snapshots.php?group_id=30402) CompilerBench.st FloatLoopBench.st IntLoopBench.st RoarParallelTinyBench.st StartupBench.st NasParallelBenchmarksIS.st BinaryTrees.st Chameleon.st FannkuchRedux.st Fasta.st NBody.st PermGeneratorRedux.st ChameneosRedux.st RoarSlopstoneBenchmark.st RoarSmopstoneBenchmark.st This also includes a small benchmark harness that allows parallel execution, i.e., benchmark for weak scalability. It also includes the necessary details to be run in batch mode from the command-line, very important to do performance regression testing for our RoarVM. An in-image-only solution does not provide enough flexibility for us. Would be interesting to discuss these things today or tomorrow at the sprint.
