Could someone please compile and run the following test program on a new 13" MacBook Pro with the Intel HD 3000 graphics. The program prints some information about the OpenCL capabilities of the hardware. Please post the output of the console in this thread.

Here is a link to the Xcode project: http://dl.dropbox.com/u/5061095/TestOpenCL.zip

Thanks! So indeed no real OpenCL support on the new 13" MBP.

I was curious about this for my model of MBP, the low end 2011 15.4". If I did this correctly, here are the results just as an FYI and a thank you for your code
 
Just for ***** & giggles:

An Aluminium Unibody MacBook 2.0GHz, 4GB RAM, Nvidia 9400m:

2011-04-18 00:12:46.939 TestOpenCL[2038:a0f] Vendor = NVIDIA
2011-04-18 00:12:46.943 TestOpenCL[2038:a0f] Device = GeForce 9400M
2011-04-18 00:12:46.944 TestOpenCL[2038:a0f] Profile = FULL_PROFILE
2011-04-18 00:12:46.944 TestOpenCL[2038:a0f] Version = OpenCL 1.0
2011-04-18 00:12:46.945 TestOpenCL[2038:a0f] Image support = YES
2011-04-18 00:12:46.946 TestOpenCL[2038:a0f] Compute units = 2

:)

I'd like to see the output for an AMD 9750....
 
this is interesting. As a follow up I ran another openCL check after running 10.7 Developer preview and Xcode 4.1 dp3. Here's the readout:

2011-04-21 04:16:33.998 TestOpenCL[2112:707] Vendor = AMD
2011-04-21 04:16:34.000 TestOpenCL[2112:707] Device = ATI Radeon HD 6490M
2011-04-21 04:16:34.001 TestOpenCL[2112:707] Profile = FULL_PROFILE
2011-04-21 04:16:34.002 TestOpenCL[2112:707] Version = OpenCL 1.1
2011-04-21 04:16:34.002 TestOpenCL[2112:707] Image support = YES
2011-04-21 04:16:34.003 TestOpenCL[2112:707] Compute units = 2
 
Could someone run the test on a 13" MBP running the latest build of Lion. Maybe Apple is updating the HD 3000 drivers, who knows :)

By the way, I have run the test on a high end 15" MBP with the AMD 6750 and these are the results:

Vendor = AMD
Device = ATI Radeon HD 6750M
Profile = FULL_PROFILE
Version = OpenCL 1.0
Image support = NO
Compute units = 5

Still no image support under Snow Leopard, but it seems that Apple will fix this with Lion.

QuartzComposer compositions that utilize the opencl patch don't seem to run at all.
 
OpenCL available?

I haven't already understood if or if not OpenCL is available on Intel HD 3000. Can anybody clarify that to me?
 
From the MacBook Air results above: No, the Intel HD 3000 doesn't support OpenCL.

My 13" MacBook Pro (with an Intel HD 3000) on 10.6.8 says no to OpenCL as well.

But not to worry. My benchmarks (using LuxMark) indicate that the Core i5 CPU in the 13" MacBook Pro is twice as fast as the CPU in the C2D Aluminum MacBook and 10x as fast as the 9400M in the C2D Aluminium MacBook. So having OpenCL support doesn't mean it's gonna be much faster.

The indications are that the Intel HD 3000 is not fully OpenCL compliant. I get that from these documents:
http://www.apple.com/finalcutpro/specs/
http://support.apple.com/kb/HT4664

The implication is that applications that rely on OpenCL may run, may run unreliably or may not run at all.

The safe route to go as of today is that if you need OpenCL capability you buy a machine with a supported ATi or nvidia card.

Be well.

Cl_invalid_work_group_size

Hi everyone,

Would like to know if someone has tried to set workGroupSize to a value greater than 1 in the new macbook air shipped with core i5-2467M. Cause i just can't.

On a MacBookPro 8,1 with Mac OS X 10.8 (Mountain Lion) your program outputs:
Code: 
2012-09-05 16:10:08.059 TestOpenCL[44960:303] No GPU support!
2012-09-05 16:10:08.061 TestOpenCL[44960:303] Vendor = Intel

This other program:
http://stackoverflow.com/a/7898347
outputs:
Code: 
Device Intel(R) Core(TM) i7-2620M CPU @ 2.70GHz supports OpenCL 1.2

It is the CPU that supports OpenCL. The HD3000 GPU does not.
