OpenCL Benchmark, for Snow Leopard only
NVIDIA: 8xxx(M), 9xxx(M), GT1xx, GT2xx, GTX2xx
ATI: 4850, 4870 - maybe 10.6.2 update needed to run withput failures
OPENCL - background information :
- OpenCL is an API for universal GPU(CPU) computing , Mac OS X 10.6 supports that
- Main difference to CUDA / ATI STEAM is: both APIs ate vendor specific. A CUDA (NV) app like badaboom(h264 on GPU) can't work on an ATI gpu and vice versa
- OpenCL is universal means:
- Xcode compiles an code which includes the source (C like) for the gpu That source is , different to
What's New
Version V2.0:
- NEW: added 3 OpenCl benches/demos from Nvidia (may run on ATI latzer with 10.6.2)
- 1. Teapot - very much difference between CPU and GPU
- 2. Memory Bandwithtest : shows CPU<>GPU bottleneck for memory transfers over PCIe
- 3. Volume Renderer
Requirements
- Intel
- Mac OS X 10.6 only
- Intel CPUs : Core2Duo and Xeon Series, not Core Duo
- OpenCL GPUs : Mac 2008+ with NVIDIA GPUs (Macbook /MBP/iMac GT120/MacPro)... Macs 2008+ with ATI GPUs - Mac OS X 10.6.2+ recommended (soon available, ATI works hard on OpenCL fixes)

- OpenCL is universal means:
- Xcode compiles an code which includes the source (C like) for the gpu That source is , different to CUDA/ATI STEAM, compiled later by OpenCL at runtime ! So same App can run on complete different gpus and also , without/less code change on CPU if no OPENCL gpu (newer ones) is available. GPU advantadge may vary - from 2 up to 40 faster, depends GPU type and CPU´s type OpenCL speedup could be even faster, if the memory transfer/access between GPU and CPU would be faster. PCIe Memory Transferlimit outperforms such GPUs like GTX285. I believe in 2011+ some new PCIe Versions will be developed for higher bandwidth over PCIe

Its also on macupdate.com does much better OpenCL benching.
Could this be released on, say, SourceForge? And under, say, an open source license?
I would love to be able to see the source code so that I could learn from it. I haven't yet been able to download the zip because "there aren't available free user slots" on rapidshare :(
I added a table for better comparison of the OpenCL benchmarks:
http://wiki.osx86project.org/wiki/index.php/OpenCL
What would be the best benchmark for evaluation of OpenCL performance? Galaxies?
@mitch_de:
could you provide in this standard benchmark a build number visible while benchmarking (better comparison)?
Thanks

Ibuild an new Galaxis V2 32K. Apple updated OpenCL API usage , perhaps helps ATI to run ? But i think ATI will need really 10.6.2 update.
Others (NVIDIA) will have a bit higher GPU GigaFlops with that version!
Be patient in CPU modes - CPU has much work to compute the 32000 stars. GPU runs much faster here but also has less that 20 FPS (GTX285) 9 FPS 8800GT.
Link (will be official if some report : work)
http://rapidshare.com/files/286234291/Galaxies_32K_V2.zip
Users with Mobile Nvidia should better use the also new V2 8K version.
GigaFlops for that mobile GPUs same as with 32K version, but more FPS especially in CPU mode
on lowend C2D mobile

Console outputs:
Build Log for Device[0]:
then after 15 seconds or so:
setupComputeDevices() failed: -7
and then I'll have to force quit the app.
Hope the X.6.1 update will fix the ati drivers.
PS.
Schöne Grüße aus Bonn ;)

Not really an problem for waiting, because no OpenCL application is on the market and i think the first will be developed end of 2009, where ati users sure got their OpenCL Framework fixed by Apple/ATI.

I'm lucky enough to own a 17" MacBook Pro - and it's very interesting that I can use both GPUs at once (9400M as renderer and 9600M as compute engine), as I didn't think this would be possible.
9600M = 46 GFLOPS
9400M = 21 GFLOPS
Hybrid = 25 GFLOPS
Given the speed of calculations, it looks like hybrid CPU+GPU must be using 9400M for GPU compute (or hybrid is not nearly as efficient). It would be a great addition if the benchmark gave two hybrid options (one for each GPU), or identified which GPU it was using.
On another note, do you think it's possible to make Galaxies use multiple GPUs for compute? I realise that this is a big ask - as you've already indicated that the 9400M GPU can only process 4K elements...
Keep up the good work!

But main work is made by Apple for the Galaxies ;)
Running parallel on more than one GPU is more complicated , but i will take a look in this direction.

Old OpenCL "Benchmark" was removed and now its replaced by Galaxies OpenCL Demo-Benchmark V1.0
- Galaxies is an much more real world OpenCL Demo and Benchmark
- no more an terminal application - OpenGL fullscreen support
- computes an universum star szene on CPU, GPU and Hybrid (CPu+GPUs) - switch with key s between that modes
- does measure computed GigaFlops and sure you also will see the speed in the moving speed of the stars - on an MacPro 1,1 an NVDIA GTX 285 is about 5 times faster - soon up to 8 times than CPUs
- do not use or report OpenCL V0.25 results anymore, the new GigaFlop results are much, much more real for OpenCL speed
- results, questions & answers you can find on the home forum:

- happy benching !

Some features your CD didnt have.
Also your GPU cant to only OpenCL commands - only much newer gpu cant run OpenCL.
Easy to remember: An GPU which cant do CoreImage, cant do OpenCL too.
So you missed nothing real, because you wont get any GPU OpenCL time values, even i would recompile the bench for CD cpus also.
I will change the CPU needs from Intel CPU to Intel C2D, Intel XEON Series and an GPU which allows OpenCL. (near all Macs build 2008 and later).

I have no ATI GPU, so such "things" are hard to fix. NVIDIAs worked all with old versions.
But i made an new version which also should run on ATI GPUs !!!
Try V025 and report result.
time results will change (less time), read the readme.

The CPU test pass nice
The Ati card do not give result after more 5min…
mouse move, but cannot move windows, cannot kill, no dock, all os freeze without mouse…
i was must force to reboot

What excat do you mean with freeze ?
- tool crash , - no response of terminal/tool, - OS X no response / freeze
If you use 10.6 , you can contact me my email ( iceguy at freenet.de), perhaps
we find an solution. Until now you are first user which uses ATI - all others used Nvidia (MacBook, MacbookPro, Imac GT120,...)
Thanks for submitting the prob.
