GL-CL interoperability in OSX

Hello

I'm trying to create a CLGL context to share data between OpenCL and OpenGL.

I tested the CLGLInteroperabilityDemo, but I get this error:

Exception in thread "AWT-EventQueue-0" com.jogamp.opencl.CLException$CLInvalidValueException: can not create CL context [error: CL_INVALID_VALUE]
        at com.jogamp.opencl.CLException.checkForError(CLException.java:67)
        at com.jogamp.opencl.CLContext.createContext(CLContext.java:228)
        at com.jogamp.opencl.gl.CLGLContext.create(CLGLContext.java:124)
        at test.GLCLInteroperabilityDemo.init(GLCLInteroperabilityDemo.java:132)
        ...

I'm on OSX 10.6.7, with a NVidia geforce 320M card. I can create pure CL contexts and everything works fine in that case, the problem happens when I attempt CL-GL. Can be this related to the GL context being 2 instead of 3?

Thanks,
Andres

It seems that I cannot create a GL3/GL4 context. If I do:

profile = GLProfile.getDefault();
...
GLDrawableFactory factory = GLDrawableFactory.getFactory(profile);
drawable = factory.createGLDrawable(win);
context = drawable.createContext(null);  

my profile is created as [GL2/GL2]. If I try profile = GLProfile.get(GLProfile.GL4bc), or any other profile after GL3, I get a "java.lang.RuntimeException: Cannot get a valid OpenGL profile".

However, if I keep using the default profile, then the GL object associated to the context seems to be of type jogamp.opengl.gl4.GL4bcImpl. But if I try context.getGL().getGL4bc(), then I get "GLException: Not a GL4bc implementation"

BTW, I'm using jocl-0.9-b330-20110411-macosx-universal. My application works inside an AWT window, just in case this information is useful.

So my questions here are:
* How to explicitly create a GL3/GL4 context? Is there something in the initialization I'm missing? Is this a current limitation in OSX? I'm running 10.6.7, everything up-to-date as far as I know.
* Is this issue related to the problem I mentioned in the first post, where I cannot create a CLGLContext?

Any insights will be greatly appreciated,
Andres

Sure ..

And since JOGL tries to get the highest fixed function profile,
I guess you are out of luck. Run test.sh as recommended in our FAQ/bug-reports.
We also have this getAvailableProfiles .. check the jogl core junit tests.

profile = GLProfile.get(GLProfile.GL4bc);
profile = GLProfile.getMaximum();

OSX ? Thought they just offered GL3 support ?
However, we haven't touched this yet, ie our current OSX GLContext selection
code may not recognize a GL3* profile.

Does your OSX machine have OpenGL 3* support ?

Hi Andres,

Unfortunately, Mac OS X 10.6.7 still only supports OpenGL 2.1. See http://developer.apple.com/graphicsimaging/opengl/capabilities/ for more details. There have been rumors of upcoming OpenGL 3 support, but nothing official yet.

Ok I see. So, this means we have to wait for Apple to release updated OpenGL drivers at some point.

Thanks a lot for the clarifications guys!

  a GL 2.x context is sufficient for GL-CL interoperability.

could you run

  java -jar jocl.jar:gluegen-rt.jar -Djava.library.path="path/to/jocl/libs:path/to/gluegen-rt/libs" com.jogamp.opencl.util.CLInfo


and post/attach the results?

best regards,
michael

thanks. fix is in progress. could take a bit longer as usual since it will also touch jogl.

Great. I appreciate your support very much!!

The 0.9-b349-20110503 package of jocl seems to incorporate some changes to address the gl-cl interop in osx.

Should I get GL-compatible devices by doing:

CLDevice[] devices = CLPlatform.getDefault(CLPlatformFilters.glSharing()).listCLDevices(CLDeviceFilters.glSharing());

?

Thanks,
Andres

  yes exactly. the first filter gives you a platform supporting at least
one device with GL interoperability or null(!). The second filter
returns all GL capable devices from the selected platform or an empty array.

there is also a platform filter checking vendor compatibility:
https://github.com/mbien/jocl/commit/c00dc66867518f32d6a2615aa8da71a52489d5d8
since its unlikely that for example NV cards will ever talk with AMD
cards and vice versa.

the CLGLContext initialisation issue on mac which was the original topic
of this thread should be fixed with this commit:
https://github.com/mbien/jocl/commit/7d44ee784ffa59146d2d1d124f5ffc482fb0f5f0

however there are no builds available yet containing the above changes,
if you are interested you will have to use my gluegen and jocl
repositories for a build.

best regards,
michael

Hi! I have met the same problem when creating cl-glcontext on OSX recently, could you tell me if the new builds are available and where I can get it? Thank you very much!

I stumbled across the same Problem this code:

_myPlatForm = CLPlatform.getDefault(CLPlatformFilters.glSharing());
_myDevice = _myPlatForm.getMaxFlopsDevice(CLDeviceFilters.glSharing());
_myGLContext = CLGLContext.create(g.gl.getContext(),_myDevice);

causes this exception:

        at cc.creativecomputing.opencl.CCOpenCL.<init>(CCOpenCL.java:119)
       
Should this be working right now I have Lion installed with these devices available:

gl sharing should be supported, any advice where to look at or how to fix this?
