I was wondering if anyone could clarify things for me.

What is OpenCL and how is it related to CUDA?
I could not find much explaining OpenCL.

Have you seen the Wiki entry for OpenCL?

What are you trying to do?

Yes, I have seen the wiki and it did not resolve my question.

I just wanted to understand if OpenCL is creating a cross platform thing as CUDA does for NVIDIA cards?

From the OpenCL site I saw that AMD, NVIDIA, and Intel were supporting OpenCL. Can anyone help to explain or correct me thanks?

I found this at the nVidia CUDA forums: How to understand"CUDA support OpenCL"? and CUDA vs OpenCL

Perhaps that you can better ask at their forums.

I think that the most important thing is : will Boinc manager support OpenCL ??
And consequently all the projects will be developed in a common standard ???
The actual situation I think it isn't OK.
Developing only for NVidia means lose about half of the total computing power

From my understanding of things is BOINC does not support one over the other, but as there is demand the features needed are added. So when a project requests support for ATI GPU's it will be supported. Which I think is currently in process to add support, but the real thing is the projects determine what is used so if there is no demand then there is no priority for that to be added when there are so many things that need to be done.
