Spur Garbage collection takes 4 times more when loading MSE (WAS: mse loading looks slower :()

by Vincent BLONDEAU

Hi, I made the benchmarks with the files you provided. I have more or less the same magnitude: Version 504: 0:00:01:09.021 Version 1175: 0:00:02:37.507 However, by launching it in the time profiler (MooseModel new importFromMSEStream: (StandardFileStream readOnlyFileNamed: 'd:/ArgoUML-0-34.mse')), it takes 504: 1 min 55 1175: 4 min 25 Well there is a delta... After investigation, the standard process has almost the same duration (120 secs for prespur and 140 secs for spur). But, there is a large difference in GC time: 504: not spur **Memory** old +144,822,000 bytes young -8,293,660 bytes used +136,528,340 bytes free -104,186,788 bytes **GCs** full 1 totalling 965ms (1.0% uptime), avg 965.0ms incr 3264 totalling 42,279ms (33.0% uptime), avg 13.0ms tenures 2,497 (avg 1 GCs/tenure) root table 0 overflows 1175: spur **Memory** old +0 bytes young +340,048 bytes used +340,048 bytes free -340,048 bytes **GCs** full 7 totalling 145,003ms (66.0% uptime), avg 20715.0ms incr 3288 totalling 30,912ms (14.0% uptime), avg 9.0ms tenures 7,146,505 (avg 0 GCs/tenure) root table 0 overflows Total GC time 504: 43 secs 1175: 176 secs See the performance reports attached. I let VM people take care of the issue ;) Cheers, Vincent -----Original Message----- From: moose-dev-bounces(a)list.inf.unibe.ch [mailto:moose-dev-bounces@list.inf.unibe.ch] On Behalf Of Tudor Girba Sent: dimanche 24 janvier 2016 09:08 To: Moose-related development Subject: [Moose-dev] Re: mse loading looks slower :( Hi, I am talking about the difference between Moose 6 images: - October 7: https://ci.inria.fr/moose/job/moose-6.0/504/artifact/moose-6.0.zip - yesterday: https://ci.inria.fr/moose/job/moose-6.0/1175/artifact/moose-6.0.zip Multiple things did change, but not in Moose. In the end, I would like to understand where the slowness comes. Maybe it comes from Spur itself, but maybe it comes from somewhere else.

Moose image font is sharp

by Blondeau Vincent

Hi, I just opened a new Moose image and the font is sharper than a Pharo image... Is it wanted? [cid:image001.png@01D1577F.87DDFAF0] Updating the font doesn't resolve the problem.

by Tudor Girba

What should we use instead? Array? nil when it’s empty? How about introducing some sort of a NilDictionary? Would anyone like to experiment?

Probably a bit more. Before loading, there were 172 instances of SmallDictionary. After loading, 558293, of which 30194 contain something. Stephan

mse loading looks slower :(

by Tudor Girba

Hi, I am doing some performance testing of Moose with the Spur VM on Mac. I tried to load an MSE file with ArgoUML 0.34 and on my machine it loads twice as slow with Spur than before: - PreSpur: 0:00:01:07.272 - Spur: 0:00:02:10.508 Here is the reference file: https://dl.dropboxusercontent.com/u/18323746/Tmp/ArgoUML-0-34.mse.zip And here is the script: [ MooseModel new importFromMSEStream: (StandardFileStream readOnlyFileNamed: (FileSystem workingDirectory / 'src' / 'ArgoUML-0-34' / 'ArgoUML-0-34.mse') fullName). ] timeToRun Do you get the same?

Specific Domain Visualizations: a glimpse of medicine public data released by governments

by Offray Vladimir Luna Cárdenas

Hi, As I told you before, I have been using Pharo/Moose/Roassal to approach certain problems by agile prototyping and visualization. It has been a really empowering community and technology and even a newbie can feel more eloquent talking to/with computers, so thanks as always. Here is the blog post with more details: http://mutabit.com/offray/blog/en/entry/sdv-infomed And here the tweet if you're in that network and want to reshare: https://twitter.com/offrayLC/status/689854446541611008 Hopefully I have been clear in the blog, but any advice to my almost self taught English, or proof reading or improvements are welcomed. I also hope putting proper credits to all the people involved in this visualization. And hopefully soon (at some point in February) I will be sharing some advances in the interactive notebook front also. Cheers, Offray

roassal2 seems to work well now

by Tudor Girba

Hi, With the latest development, Roassal2 seems to work well. For example, the rendering of the logical view of Glamour browsers was broken, and now it works well. This is great news. Is this just my impression? Do we know if there are still open issues with the FFI in this area? Cheers, Doru -- www.tudorgirba.com www.feenk.com "Every thing should have the right to be different."

Telescope

by Axel Lefaux

Bonjours, J'ai voulu installer Telescope sur Pharo 4.0. Hors lors de sa configuration, j'ai eu un Warning à propos de ce package qui dépend d'autre packages : This package depends on the following classes: RTObject RTView RTClusterLayout RTAbstractNormalizer RTShape J'ai donc téléchargé une image de Moose 5.1. L'installation réussie, j'ai essayé de suivre "Tutorial end-user" et lors du premier exemple, le message n'était pas compris, le receveur du "new" est "null". Cordialement, Axel Lefaux.

[ann] spotter processors as settings

by Tudor Girba

Hi, We now have a new little feature in Spotter. Take a look: Basically, you will get a setting for each processor defined in the image. This happens dynamically. If you disable the setting, the processor will not be available anymore. Please give this a try and let us know what you think. We would also like a code review related to the way we deal with dynamic settings. Right now, the magic is done in GTSpotterExtensionSettings (this is real magic - read the class comment), but the current solution relies on a doesNotUnderstand: to maintain the list of disabled processors. I would more prefer it if we could create a DynamicSettingDeclaration that would be able to pass arguments to one central selector.
