no work
links no work!!!!!!!! instructions??????:(

Hi, someone posted wrong (very OLD=Version1=removed) Links:
Here are my (i compiled that stuff) - all need 10.6.x. ATI has problems with OpenCL, so only the Displacement works here. Galaxies cant run (need 10.6.2+...get fixed by Apple/ATI) OpenCLBench_Displacement_Version 2 http://rapidshare.com/files/28747429...acement_V2.zip Galaxies_8K_Version 2 - for slow OpenCL GPUs http://rapidshare.com/files/28623515...xies_8K_V2.zip Galaxies_32K_Version 2 - for fast gpus http://rapidshare.com/files/28623429...ies_32K_V2.zip Galaxies does an Starsimulation. If you have slow OpenCL GPU and/or slow CPU best use first the 8K Version. Displacement does some rendering/shining. Very soon an OpenCL Smoke Particles demo will be available: http://freenet-homepage.de/amichalak..._particles.jpg |
SMOKE! Whered you get that! I want try it =D

Intel C2D 2,66@3,20 GHz + GeForce 8600GTS 512 Mb
Code:
1 OpenCL platform found!Displacement V2: [GPU]: Shader 1/Shader 2 Compute: 24 ms. / 19 ms. Display: 41 fps. / 52 fps. Galaxy 8K V2: Vector Single Core: 12 Vector MultiCore: 22 GeForce 8600GTS: 52 Hybrid MultiCore CPU+GPU: 29 I didnt try the 32K, I suppose is too much for this old card... |
Smoke Partikels and all others are from Apple Dev Source. Just compiled.
For those only want to look, here is the Smoke Particles video: http://www.youtube.com/watch?v=-7yTRxJhVps On that Link you see also the DL Link (10 MB) and how to run instructions (easy ;) ) Only CUDA driver must be installed, Links also at the video link above. CUDA has the advantage to run also in OS X 10.5 , OpenCL is 10.6! Disadvantage (like ATI STEAM) is thats vendoe specific - CUDA app runs only on NVIDIA , and ATI STEAM (no OS X) only on ATI GPUS. OpenCL should be universal. Until now its not, because ATI gpus have trouble with OpenCL. OpenCL main difference to CUDA + ATI STEAM is, that OpenCL part of the App is compiled at runtime ! So The dev must NOT compile that for an specific gpu. The openCL Source will compiled for the specific gpu the OpenCL framework finds at runtime. But OpenCL has indeed also some things to code to optimize the source for the complete different (in features+speed) gpus. So OpenCL has great feature but is more work (also brain work) to get an big bandwith of really universal gpu computing. |
I passed all the test except the VolumeRender.Here's the content of the txt file:
