OpenMP and Pd
by Pedro Lopes 06 Dec '10

06 Dec '10

I was trying to include pragma comments of OpenMp in a PD external, but it does not seem to work for some reason. I tryed to look a bit on the web about Pd and parallel code but couldn't find any thing specific about OpenMP - does the current architecture of Pd allow parallelization with OpenMP directives? I included a simple directive, it compiled with -fopenmp with no error nor warnings but in creation time (inside PD): >undefined symbol: GOMP_parallel_start > dtw >... couldn't create I found this [1] and also some references to Miller's conference about the topic in Brasil but couldn't figure out exactly if OpenMP is allowed in pd external code. best regards, Pedro Lopes [1] http://www.eecs.berkeley.edu/~demmel/cs267_Spr10/Lectures/Wessel_Final_ICMC…<http://www.eecs.berkeley.edu/%7Edemmel/cs267_Spr10/Lectures/Wessel_Final_IC…> -- Pedro Lopes contacto: jazz(a)radiozero.pt website: http://web.ist.utl.pt/Pedro.Lopes

GridFlow on Android
by Mathieu Bouchard 23 Nov '10

23 Nov '10

Got GridFlow on Android working, with no options at all. Therefore, [#out window] does not work, and there's no other form of window output, because there is no x11, no quartz, no sdl, no aalib, no tk, no gem and no pdp (those are the seven window outputs that GF can support). Seems like we will need an 8th one, specifically for Android, unless someone gets Gem or PDP to work on that. The test I made was just to compute a matrix and print it in the console. _______________________________________________________________________ | Mathieu Bouchard ------------------------------ Villeray, Montréal, QC

Re: [PD] Stupid arduino question
by Collin 18 Nov '10

This is a little late, so you may not want to get into it, but I once hacked firmata a little, so that it could read an encoder. I'll attach it.

Pd 20% idle CPU usage on MBP
by Jamie Bullock 16 Nov '10

16 Nov '10

Hi, On my Macbook Pro (2.5 GHz Core 2 Duo), Pd's idle CPU usage is 15-20%. This is really high for an application in idle state. I get this regardless of the version of Pd I use -- I've tested with 0.42 and 0.43 latest. The load is in the server, the GUI CPU usage seems quite low. Does anyone know why this is? Is there anything that can be done to improve the situation? Jamie -- http://www.jamiebullock.com

[PD-announce] libpd: An embeddable sound engine for Android, iOS, C, Java, and more
by Hans-Christoph Steiner 10 Nov '10

10 Nov '10

libpd has reached a 0.1 release, enabling developers to use Pd as a sound engine in their applications. Out of the gate, we have extensive code samples for Android 1.5 and later, plus the basic tools to work on iOS (recent armv7 recommended for now, with other devices soon). In the near future, embedding Pd patches inside tools like Processing/Java, OpenFrameworks/C++, and Python should be just as easy. The library is based on Pd vanilla, so this is not a fork of Pd; you can use patches in it just as you would in any other version. Developers will find the library, code snippets (for Android; iOS is coming), and even some handy abstractions: http://gitorious.org/pdlib/ To learn more: Article on the release at createdigitalmusic: http://bit.ly/libpdishere Group for discussing Pd on mobile, embedded, and using libpd: http://noisepages.com/groups/pd-everywhere/ End users with Android phones or tablets can try out packages now: http://gitorious.org/pdlib/pages/Packages ... in addition to patches from Chris detailed in the CDM post above. libpd available is thanks to the work of Peter Brinkmann, with testing, further development, documentation, and other contributions from the RjDj team (who are now adopting it in their future development work), Hans-Christoph Steiner, Chris McCormick (who has also added the ability to make HTML5 web interfaces), and Peter Kirn, along with members of the NYC Patching Circle at NYC Resistor. _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

joining segments
by ronni montoya 01 Nov '10

01 Nov '10

Hi, I was wondering which approaches does exist for creating waveforms from a set of segments , or how can i join segments together to create a waveform in a way that each segments starting amplitude is the previous segments ending amplitude? Each segment is a segment of a waveform stored in a table Bye R.
