Re: [PD] -nosleep flag not doing anything? (Ubuntu 10.4 - Pd-extended 0.42.5)
Yes, exactly! Oss doesn't seem to accept the -nosleep flag. When using alsa it works. However, using oss without the -rt and -nosleep flags gives me about the same or even slightly better performance than using alsa with these flags active. Looks like oss has some different internal system priorities compared to alsa. Anyway, thank you - it's doing something now! Ingo It's posible the difference is in the choice of audio API (oss vs. alsa) or something like that -- nosleep prevents Pd from explicitly sleeping but sometimes transferring data to DACs blocks the process. cheers Miller On Fri, May 07, 2010 at 03:36:33PM +0100, Pedro Lopes wrote: Here it works: $ pd -nosleep Gives one of the CPU's 100% load fulltime.

Quoting Miller: Should theoretically work on Mac too, but I don't have any 2+-processor mac to try it on. Probably does nothing on windows. In Windows XP SP3, 32 bit, using the following puredata: D:\XP32\Program Files\pd\binpd -version Pd version 0.41-4extended compiled 03:33:30 Jun 4 2009 The -nosleep fills one CPU entirely. So seems to be working. The system is the same I've reported above for Ubuntu 9.10. -- Pedro Lopes contacto: j...@radiozero.pt website: http://web.ist.utl.pt/Pedro.Lopes ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Here it works: $ pd -nosleep Gives one of the CPU's 100% load fulltime. No need to run in root for this. My startup alredy boots pd with -rt flag and I have the limits.conf tuned as reported on the wiki/documentation.
