AMD today announced the availability of the ATI Stream Software Development Kit (SDK) v2.2 with full OpenCL 1.1 support to provide developers with the tools they need to build incredible next-generation applications. By taking advantage of both CPU and GPU processing power in a given system, applications like 3D video, HD video chat and multi-display 3D gaming are possible.

A development platform created by AMD, the ATI Stream SDK v2.2 brings a wide range of tools to the developer community including support for OpenCL 1.1, in addition to Ubuntu 10.04 and Red Hat Enterprise Linux 5.5. This updated development platform empowers the developer community to accelerate applications on the CPU and GPU quickly and efficiently. The new version is available for download here.

Hmmm, so openCL has CPU fallback? that sounds obvious, but it never occurred to me until now.

(oh and you missed the S on the second last 'support')

And even with this version their clBuildProgram() function is still buggy with no apparent documentation. :p Still no support for wavefront as well.

It works fine when compiling using indirect OpenCL (through CUDA) and CUDA.

Well, to make what I said above easier for everyone, Stream still has ways to go compared to CUDA. :p

It's not really meant for games. It's aimed at HPC and General Purpose computing (e.g. using the GPU to do things the CPU already does).

What's preventing wide usage of Stream is lack of direct support from AMD developers and that they're going for the OpenCL route, which is good, but again, lack of proper documentation and dev help is keeping them down.

Now, CUDA has the same "switch to OpenCL" goal, but there are dedicated NVIDIA devs who are willing to help port/convert/rewrite applications with enthusiast and budding programmers. This is the only reason why I have an 8600GT along with my Crossfire setup.

Well I don't care who does it as long as it gets done. I'm more than certain ATI cards can do CUDA its only a matter of time (I hope).

Actually, ATI cards can't do CUDA since they implment stream processors (NVIDIA's "CUDA cores") differently. You may be confusing it with PhysX that was emulated using an ATI card a while back.

OpenCL is what would make Stream and CUDA a neutral ground. At the moment, CUDA's doing well in conversion. A situation very similar to what happened with OpenGL in the past (e.g. NVIDIA hardware extensions).

that never actually happened - what really happened, was that the guy involved got an nvidia card as a secondary GPU to process physX (physX on ATI) and it went completely out of hand... no proof was EVER given, that physX was running on the ATI GPU, and not a secondary PPU.

@Mussels

Thanks for clarification. I didn't really have any solid details on that. So it was an NVIDIA card that was used for PhysX.

I'm not really into PhysX, but it may seem that NVIDIA does truly use CUDA for PhysX if that's the case. I'll see if the PhysX code that game developers use access the video card the same way CUDA/OpenCL does.

Step in the right direction to get more out. I am proud of the OPEN CL and apparently devs are using this for things.
