Snow LeopardProblem with OpenCL kernel patch Hi, I'm trying to create a OpenCL kernel but I cannot get it work well. This program is to convert X/Y mouse position queue to an image. It looks work fine, but it gets gradually slower, and finally crashes MacOSX after several minutes. __kernel void main(__global const float *X,__global const float *Y,__wr image2d_t output)
{
int2 pos = (int2)(get_global_id(0), get_global_id(1));
float4 color;
color.x=X[pos.x]; //R
color.y=Y[pos.x]; //G
color.z=0.0; //B
if(color.x<0)
color.x=0;
if(color.y<0)
color.y=0;
if(color.x>1)
color.x=1;
if(color.y>1)
color.y=1;
write_imagef(output, pos, color);
}I set queue size to 80 in qc, so that it creates 80x1 pixels image. I found that it gets work well when I continue to click "Sample Now" button in "Advanced Kernel Settings" every minute, but I have no idea to get code work stably. Could you help me? Cheers
OpenCL Meshes I had been studying the Aurora [Rainbow Snow] example recently that was posted up in the Developer Sample Code section sometime ago. I was peaked to look again when the Iteration degradation problem cropped up earlier this week from itsthejayj. I already knew that the OpenCL audio spectrum mesh creation routine worked outside of iTunes and produced a pretty mesh ribbon. It completely fails to show inside of iTunes. Either way, the composition produced a load of Console messages, patches failing and segmentation fault crashes. Even if I attached a static .dae, then the Fog Environment, containing a Camera macro patch, would still bleat a lot , but only if the Audio Peak information were lacking slightly - silent to low points. If only those messages didn't presage the aforementioned crashes, I wouldn't be so worried. The Iterative string of errors doesn't end until the Console is reloaded. Definitely a structural problem and one that the use of Iterations means keeps repeating even after the Render has been ceased. This behaviour also evidences when running the visualizer in iTunes and not playing any audio. I don't think this is specifically an Open CL, .dae related issue BTW. However, thus far I have not been able to reproduce the problem when replacing the Mesh with a simple Circle. In fact , the problem seems to to have 'gone away' since I forced the Enable to be on only when Audio was running, whilst I typed up this report / post :-). If anyone can reproduce the problem I'd be interested to hear. BTW - I do already know that when iTunes stops audio this visualizer kind of freeze frames and the QC Render window blacks out , the iTunes re-renders on fresh audio and the QC needs a stop/ restart on the Render window FYFI :-)
GL Tools 1.3 in Snow Leopard - Resulting Crashes - probably post update 10.6.1The following was the resulting output when running GL Tools 1.3 on Snow Leopard and saving a composition from Quartz Composer that had originally been produced on the PPC with GLTools 1.1, then 1.2 and finally 1.3. iTunes Visualizer was running in the background - probably unimportant. *~ - edit - as it happens, upon closer examination, when iTunes isn't running the crash does not occur - probably down to the queueing of the current data state from the music :-) This happened in both 32 and 64 bit mode. The same standard working procedure results in the same type of crash upon the PPC and the crash can be avoided by not explicitly going down this route. It is being precipitated specifically by having Command + W , or otherwise clicked to close down either the Viewer or Editor window, leaving the other open. Once this has been done and one is left with the remaining QC window, when one Command + W's to close the remaining window and clicks on the save dialog button, the application crashes. Work Around Work can be saved if one saves Command + S at the first of the two open windows, then proceeds to close the remaining window and clicks the Don't Save button. So I guess this workaround wouldn't be needed if one wasn't working on a Music Visualizer protocol item with iTunes Visualizer running just to see if it really does do what one wanted it to do.

Is it SL Compatible or Broken (?), Plug-Ins / Patches - Discussion After some back and forth with Offonoll, it came to mind that a forum topic needed to be started which catalogues in one central location what does or doesn't work in QC4, Snow Leopard, that did work in QC3. I'm not talking about aberrations in the app itself (like Editor or Viewer issues), but about issues with plug-ins and patches. I would also like this to apply to Apple "patches"; the stock ones, available via the the QC patch library interface. (Do not devolve into discussing app bugs that involved the Editor or Viewer, focus of app windows, etc., if possible.) It would be great if people could use this as a thread to gather all of this info into one place, for easy reference. Some thoughts to keep this as constructive as possible: -A plugin/patch may appear to work, but may have various functions or "sub-patches" that work improperly. That said, it's not always going to be a straightforward answer about whether a plugin or patch works or doesn't work. We will probably see many that work "overall" but with some lingering broken functionality. -Please indicate if you are running QC in 32 bit mode of 64 bit mode. Some plugins and patches will run fine in QC, when the QC app is run in 32 bit mode, but won't run in 64 bit. Find the app in your Developer folder, do a "get info" and check the 32 bit mode to run in 32 bit). -Indicate what OS version you are running. ("Apple" logo on the menu bar/ "about this Mac".) -Generality doesn't help, while specificity does. Be as specific as possible about what you were doing when something didn't work, and possibly include sample qtz's or other needed code. No one shall write "yo, ___ doesn't work". Pretty please. -This isn't explicitly about Kineme patches at all. This is about ALL patches, mainly 3rd party, obscure and rare ones, Kineme or otherwise, but also function that is broken in Apple patches, if applicable. It would also be more productive if this wasn't only centered on what is broken, but also what has been vetted to work well; if something works perfectly in your estimation, please share that info. Similarly, if anyone notes that any bugs can be mitigated by following certain steps (eg., it works when QC is run in 32 bit, but not 64 bit, or another plugin of feature has superseded the old one), please let that be known as well. Let's try to keep new patches/features out of this, or it could simply turn into a discussion about OpenCL issues.
Snow Leopard and Leopard update Performance Update 1.0Snow Leopard and Leopard update Performance Update 1.0 is now available - addressing hard drive - performance freeze issues - see http://support.apple.com/kb/HT3901 - just might help with some , but probably by no means all reported freeze up issues. Does require a restart.
