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

Re: [PD] call for testers for L2Ork iteration of pd-extended (based on 0.42.x branch)
by Ivica Ico Bukvic 06 Dec '10

Great suggestion! That might work quite nicely. We only have to make sure for legacy purposes that wherever in the old code this variable is being checked that it can gracefully handle values less than 0. That said, my top priority as of right now is further testing current code as well as continuing to work on my neck piece. Beyond that I would like to make all iem objects resizable via GUI, revamp the to-front and to-back algorithm so that it does not rely upon undo, followed by an "infinite" undo, and then tooltips, improved color picker, improve upon the tidy algorithm, and then weed through the documentation and externals and only keep those that are well maintained and are not redundant. Your suggestion might fit nicely somewhere inside here as well. I would also like to see Qt-ified (or better yet juce-ified) version of the whole thing. This will however have to wait. Long story short it might be a while before I make the next big push. In the meantime, as always, contributions will be most welcome provided they do not break the backwards compatibility. Cheers!

Re: [PD] Gridflow+ L2Ork pd-extended (was: L2Ork pd-extended release candidate 1 now available)

I am not sure if you already mentioned this but did you actually try recompiling gridflow from scratch or are you using one of the precompiled packages in conjunction with the l2ork pd-extended?

plugin to make menu look like Ubuntu Maverick
by Hans-Christoph Steiner 06 Dec '10

06 Dec '10

I was just playing with the menubar in 0.43, and thought I'd try to make it look like the menubars in Ubuntu/Maverick. This one-liner gets really close, the color might be slightly of: .menubar configure -background grey19 -foreground white -borderwidth 0 -font {Ubuntu 11} Just drop this file into ~/pd-externals and launch 0.43: .hc ---------------------------------------------------------------------------- ¡El pueblo unido jamás será vencido!

Hi list, i hope you enjoy my (completely uncommercial) work: http://vimeo.com/17474435 made with Pd/Gem. We were filming visitors to a theater festival at the beginning of the show through a mirror without their knowing. during the programm we were selecting snippets from that footage. after the theatre program we were jamming live with that audiovisual material. some of the visitors were not so pleased, but the audience in general loved it. I uploaded it anyway. m.

More SVN build questions
by Ivica Ico Bukvic 05 Dec '10

05 Dec '10

Hans, Your lastest nightly snapshot is also missing flatspace (but at least it does build libdir,flib, and toxy). I've had to build libdir, flib, and toxy manually, so I guess there is a workaround for that (in other words the current svn build script simply ignores building those for whatever reason). But the absence of flatspace even in your nightly builds is baffling. Is this thing then deprecated in latest svn? Ico
