GUI performance clarification
by Lee Azzarello 14 Mar '10

14 Mar '10

Hot on the heels of the great GUI rewrite thread, I have a simple question that would help clarify some CPU performance questions I have with my current project. I have incoming serial data from an arduino. This data is getting buffered every n milliseconds and sent to a vslider object. I have 6 channels of data with a vslider on each, so 6 vsliders and 6 buffers. If I set n to 20ms, my dual core 2.4 ghz CPU with an i945 graphics card on Linux 2.6.32 hits 100% with no audio processing. If I lower n to 60ms the CPU usage drops to about 15%. Is this the expected performance for a vslider? -lee

udpreceive~
by Michal Seta 11 Mar '10

11 Mar '10

Hello Martin and others, I think I should bring this issue to the general pd-dev attention because there seem to be some serious glitches in the way pd interacts with externals that try to send audio signal over the network. Just to put everyone on a more or less the same page, I have been trying to use pd in a situation where several musician will improvise together over a local network. The main requirement is that the playing happens over WiFi. I had netsend~/netreceive~ crash regularly and Mr Peach's udpsend~/receive~ appeared on my radar. They, too, crash, on WiFi networks. Using them on wired connections seems to be quite reliable (but I have not tested with wires extensively). It seems that udpreceive~ is the source of crashes. I played quite a bit with udpreceive~ but I cannot put my finger on any particular bug. Even running just one udpreceive~ listening on 1 channel it will eventually crash. I get sometimes this mysterious message: error: udpreceive~: incoming stream has too many channels (2) Even if I send 1 channel and receive 1. At some point this happended to print into the pd console as well udpreceive~: EFAULT: 0x832dda0 1900572 1576380 udpreceive~: recv data: Bad address (14) The above messages are, I guess, udpreceive~ specific gdb backtraces show that the problem lies deeper: #0 0x01834f21 in ??

This last one is particularly puzzling to me as I don't understand what canvas has to do with signals (the crash happened the moment I clicked on a message box...) Most of these tests were done on pd 0.42.5-extended-20100110 and pd vanilla 0.41-4 on Ubuntu Karmic and/or Ubuntu Jaunty. I had also tested a few times on MaxOSX 10.5 I believe, pd-extended, probably 0.41-something (I can check the version later if it is at all important). The crashes happen at different points in time, sometimes as soon as signal connection is established sometimes it will run for 1 - 10 minutes. The same behaviour is exhibited when running pd with -nogui option and irrespective of mouse/keyboard interactions. Any ideas anyone? Thanks in advance ./MiS
