what makes Pd-extended 0.43 so CPU-hungry?
by katja 12 Dec '12

12 Dec '12

Hello, I've installed Pd-extended 0.43 versions (Linux and OSX) from the autobuilds several times in the past year. The latest builds seem to work fine in many aspects, but they are still so CPU-hungry: ~ 50% more than Pd-extended 0.42. How come? A while ago, the new PortAudio version was blamed (http://www.mail-archive.com/pd-list@iem.at/msg50357.html). Indeed, using Jack solves the load difference for OSX. But on Debian I also observe a 50% load increase for the new Pd-extended. No matter if ALSA or Jack is used. Does anyone have similar observations with Linux builds? BTW, I'm happy with Tk 8.5's antialiased font! Initially, I feared that antialiasing was responsible for increased load on Debian, but disabling GUI updates did not make noticeable difference. It seems that antialiasing is done rather efficiently, the performance drop must be somewhere else. Katja

I consider this something everyone should install now. The progress bar is a good enhancement. I wonder if it could somehow fit in to the GUI elements better somehow. Its fine how it is, but it seems a little out of place. Looks like there are some debug messages still in it, I get these when hovering: filename is 5.reference/all_about_arrays.pd basedir is /Applications/Pd-0.43.3-extended-20121008.app/Contents/Resources/doc filename is 5.reference/loop~-help.pd basedir is /Applications/Pd-0.43.3-extended-20121008.app/Contents/Resources/doc filename is 5.reference/all_about_arrays.pd filelist is 7751 filelist is 7751 .hc

Re: [PD] close all patches on quit sourceforge patch
by Ivica Ico Bukvic 08 Nov '12

08 Nov '12

Hans and Iohannes, The following is FYI. Several months ago I integrated the close all patches before quitting patch in pd-l2ork and since then I've been experiencing extremely sporadic crashes on close that would hang pd-l2ork. Now, I am not sure this is because of architectural differences between regular pd and pd-l2ork but I doubt it since most of the said components are very similar if not identical. The bottom line is this only occurs on very low-powered machines (e.g. netbook) and relatively large patches and even then it does so very sporadically. Consequently, I implemented an improvement to the closing mechanism that consists of 2 additional steps and apparently alleviates said problems entirely: 1) disable further redraws (this prevents calling functions that may be referencing null pointers)--I have a special global var for this which is also being used to optimize redrawing (many actions in pd-l2ork are several times faster than regular pd as a result of this implementation--just look for do_not_redraw call in the source if curious) 2) suspend dsp before going through the patches (all sub-patches try to suspend it and resume it but for some reason, due to asynchronous nature of communication between tcl and c funny things occasionally happen on low-powered machines, so this way we ensure it is entirely off throughout the whole destruction process) Hope this helps!

[PD-announce] Pd-extended 0.43.4 beta release, its almost done!
by Hans-Christoph Steiner 05 Nov '12

05 Nov '12

So in a little burst of activity, there has been new work on the Pd-extended 0.43 release. A bunch of bugs have been fixed, a new Windows XP build server is up and running, a couple of bugs are still outstanding. Overall, things are looking good and ready to go! Unless you are affected by one of the bugs listed below, I think that this beta version is already much better than the last release. You can get it here: https://puredata.info/downloads/pd-extended/releases/0.43.4 If you are running Ubuntu or Linux Mint (lucid thru quantal), you can add this PPA to automatically find and install Pd-extended beta updates: https://launchpad.net/~eighthave/+archive/pd-extended/ Running this command in the Terminal is the easiest way to add this PPA to your machine: sudo add-apt-repository ppa:eighthave/pd-extended Unfixed bugs ------------ These are the bugs that are not yet fixed. If you can help with them we appreciate all the help we can get.
