Hello,
I'm going to work on a Mac Pro with MacOsX.6.7 and the latest stable Pd-extended 0.42.5. I would like to connect four PS3 Eye on this computer and use GEM with pix_video to read these four devices in four instance of Pd (=> one camera per instance of pd). I will use Macam driver (or something else ?) Is it easy to get each camera working in the same time on this system ? Do you have experience in this area ? Thanx for help. ++

i'm successfully using 4 PS3 cam's in parallel within one Pd/Gem instance on linux. however, i heard rumours that there are problems on OSX.

Thanx Peter and IOhannes for your answer. it's not very reassuring... I test this configuration today. I will keep you informed. And if it is not working, i will switch to Linux. About Linux (Ubuntu), is there someone who know if the graphics cards (2 ATI Radeon HD 5770) work fine under this OS ? ++

My experience with just one cam on OSX and Pd-extended 42 was that object creation order mattered because each [pix_video] object automatically opens the first available camera AND the "device 1" method didn't work. So, to access only the 2nd camera, I had to create two objects and only use the 2nd one.
using 4 [pix_video] objects for 4 cameras may work, but they will be assigned by creation order.

Thanx Mathieu,
I will give it a try with your tips. I have started to install Ubuntu 10.04 on the Mac Pro and i think i will use this OS.
In fact, i am crazy because i have installed two ATI Radeon HD 5770 on this Mac Pro (version 5.1). Each card has 2 Mini Display Ports and 1 DVI port. On the Apple website it is write each graphic card accept a resolution of 2560x1600 px. When i plug 2 TV screen (HDMI and each screen with 1280x768px) on the 2 Mini Display Port on one card (with an adapter Mini Display Port/HDMI), it works fine. But if i use the second card with the same configuration (so 4 TV screen on the 4 Mini Display Port), it seems the computer have not enough power, the Finder quit each 10 second. I use MacOSX.6.6 and this is not the lastest version (the lastest is X.6.7 and maybe it is working with this version but now i have no time to test this config).
With Ubuntu, the sytem start to load then the 4 screens stay black. I have to unplug the 2 cables on one graphic card to boot normaly. So i can only use 2 screens.
I don't know where is the problem (power ? Apple computers ?). If someone have any experience on this problem, i will be happy to listen him.
Now, the solution that i am going to use : 1 Mac Pro with Ubuntu and one graphic card (ATI Radeon HD 5770) 1 PC with Ubuntu and one graphic card (NVidia GT 440 or NVidia GTX 460) ++

I think two of those cards might draw too much power to run at the same time? Also, check the PCIe lane speeds and try running them at 4x or 8x rather than 16x.
AS far as getting 4 of the same cam running, it depends on how the driver presents multiple cams to Quicktime. It might show up as one device with four inputs, for example. Use the 'dialog' message to check it out.

I find both OSX and ubuntu start to tweak out after 2 /dev/videos are started I have tested this on ubuntu 10.04 with pdp_qt running 2 logitech Pro 4000 webcams
I find much better response with multiple hauppauge cards with s-video ins I can get 4 without squawks

Hello Chris,
If I have time to do this test the next time i will do it (putting the graphic card on the 4x PCIe bus). Now, it works fine with 2 MacPro (with one graphic card and 2 PS3 Eye on each MacPro) and Ubuntu 10.04. I have installed PureData 0.42.5, last GEM from SVN and ATI driver Catalyst for the Radeon HD 5770 and the acceleration is OK. When i was using 'dialog' message, i can't remember what i got. Thanx for your help and suggestion. I will try to test all your recommandations the next time. One remark : it seems the graphic acceleration is better under Ubuntu than MacOSX. Is there a problem with the driver under MacOSX ? (The same patch worked faster under Ubuntu). ++

hello,
from my experience, Gem is 2 times faster on the same computer using ubuntu than osX. thanks to nvidia profiling tools, Nicolas pointed that gem is limited to 50% usage of the GPU. there is certainly a limitation somewhere on osX preventing application to use full performance of the hardware.
so, you applications are slower, but the interface will always be smooth...

It would be interresting to see if proprietary software runs better.
In the blender osx faq :
How can I get Blender running faster?
OSX Aqua uses OpenGL extensively for drawing, so it might happen your 3d card doesn't have sufficient memory to draw accellerated with a larger window size. A solution that works well, is switching to less screen colors: set the menu in "System Preferences -> Displays -> colors" at "thousands of colors".
Another common issue is with using the Dock on top of the Blender window. This kind of transparent blending takes a lot of 3d card drawing powers, and can better be avoided by setting the Dock to become auto-hide.

There's a setting in Gnome/Ubuntu for choosing no effects, normal effects, extra effects. This may make a difference. What kind of performance difference do you get when you change that setting ? It might explain part of what happens on OSX, perhaps (where, afaik, you don't have such a setting, and effects level is somewhere between ubuntu's normal and extra levels).

Yep, of course, you have to choose 'no effect' in 'Appearance' to get best frame rate. MacOSX should have this option too. ++

There's a setting in Gnome/Ubuntu for choosing no effects, normal effects, extra effects. This may make a difference. What kind of performance difference do you get when you change that setting ? It might explain part of what happens on OSX, perhaps (where, afaik, you don't have such a setting, and effects level is somewhere between ubuntu's normal and extra levels).
Yep, of course, you have to choose 'no effect' in 'Appearance' to get best frame rate. MacOSX should have this option too.
i havent made heavy benchmarck, but i dont see lot's of difference between affect and no effect. (except the fact that i can't be sync on the screen with effect on) c

I haven't used it in a while, but OSX probably still has these options scattered around the place, like choosing whether or not to 'animate' various actions, choosing to auto-hide the dock, choosing transparencies in various places .. but not a single switch and some things are not accessible directly by the GUI but are all settable via CL so a script to turn all off would be straightforward, or use third party preference setting apps to do it for you if unix style CL stuff is not for you - I remember something like 'onyx' was a good one of these.

What do the letters «CL» stand for ?

Probably Command Line, as in a terminal, as opposed to Graphical User Interface.

CLI is common usage, though a name clash (try to search for "Microsoft CLI").
CL, otoh, is less common, and is much more of a name clash with lots of abbreviations that I know, and most likely even more abbreviations that I don't know.

Ah, also, is it precisely 50 %, or exactly 50 % ?
If it's exactly 50 % (or slightly under), can it be some kind of reservation per CPU ?

Does the performance improve in fullscreen? I can see having to share time with the rest of the GUI, but in full screen there is nothing else taking time.

Hello Chris,
If I have time to do this test the next time i will do it (putting the graphic card on the 4x PCIe bus). Now, it works fine with 2 MacPro (with one graphic card and 2 PS3 Eye on each MacPro) and Ubuntu 10.04. I have installed PureData 0.42.5, last GEM from SVN and ATI driver Catalyst for the Radeon HD 5770 and the acceleration is OK. When i was using 'dialog' message, i can't remember what i got. Thanx for your help and suggestion. I will try to test all your recommandations the next time. One remark : it seems the graphic acceleration is better under Ubuntu than MacOSX. Is there a problem with the driver under MacOSX ? (The same patch worked faster under Ubuntu). ++

I think two of those cards might draw too much power to run at the same time? Also, check the PCIe lane speeds and try running them at 4x or 8x rather than 16x.
AS far as getting 4 of the same cam running, it depends on how the driver presents multiple cams to Quicktime. It might show up as one device with four inputs, for example. Use the 'dialog' message to check it out.

Thanx Mathieu,
I will give it a try with your tips. I have started to install Ubuntu 10.04 on the Mac Pro and i think i will use this OS.
In fact, i am crazy because i have installed two ATI Radeon HD 5770 on this Mac Pro (version 5.1). Each card has 2 Mini Display Ports and 1 DVI port. On the Apple website it is write each graphic card accept a resolution of 2560x1600 px. When i plug 2 TV screen (HDMI and each screen with 1280x768px) on the 2 Mini Display Port on one card (with an adapter Mini Display Port/HDMI), it works fine. But if i use the second card with the same configuration (so 4 TV screen on the 4 Mini Display Port), it seems the computer have not enough power, the Finder quit each 10 second. I use MacOSX.6.6 and this is not the lastest version (the lastest is X.6.7 and maybe it is working with this version but now i have no time to test this config).
With Ubuntu, the sytem start to load then the 4 screens stay black. I have to unplug the 2 cables on one graphic card to boot normaly. So i can only use 2 screens.
I don't know where is the problem (power ? Apple computers ?). If someone have any experience on this problem, i will be happy to listen him.
Now, the solution that i am going to use : 1 Mac Pro with Ubuntu and one graphic card (ATI Radeon HD 5770) 1 PC with Ubuntu and one graphic card (NVidia GT 440 or NVidia GTX 460) ++

My experience with just one cam on OSX and Pd-extended 42 was that
object
creation order mattered because each [pix_video] object automatically opens the first available camera AND the "device 1" method didn't
work.
So, to access only the 2nd camera, I had to create two objects and
only
use the 2nd one.
using 4 [pix_video] objects for 4 cameras may work, but they will be assigned by creation order.

Doesn't that depend on the good will of other apps to not render anything that isn't going to be displayed ? Do all the other apps even know that they are hidden ? What does OSX's window manager tell all other windows when going to fullscreen mode ?

I don't think the OS tells the app anything - it just doesn't give the app UI events or call it's drawing routines.
Hello all,
I didn't had time to make heavy testing. But I tried some things today and it seems finally I manage to go further than 50% of the GPU. You can see the evolution of my graph here if you want: http://nim.on.free.fr/data/gem_perf.png It is with different testing : changing resolution / frame / options Auto-hiding the dock doesn't seems to change a thing, and sending fullscreen before creating the window did not significantly change the GPU usage. I'll try to do some more professional testing with Cyrille tomorrow. What is the best way to test the GPU usage, drawing numerous squares? There is also many different parameters to monitor and i can display some others if you prefer. The tool i am using is a developper tool from apple : OpenGl Driver Monitor

when rendering many squares, the bottle neck is locate on the PCI bus, for the communication between cpu and gpu. pure gpu computing can be tested with heavy shader usage.

unless that alleged 50% protect-the-interface GPU limit is still imposed of course.

well, "dialog" will only give you something meaningfull, if the used

Yep, here i was talking about 'dialog' on MacOSX ;) I remember to have something like 'Macam #0 PS3Eye', 'Macam #1 PS3Eye', etc. with the 'dialog' window in the source section. ++
