I just finished the code for google summer of code today. I supports every cpu that is supported by gcc. And it also supports the cell. It does not have an OpenCL C compiler yet or support for the image api.

The thing you must know about GPUs is that, currently, threads in groups of 32 all have to do the SAME THING or you get slower performance than a CPU.

Well I guess you are right. It's just I spent the whole summer working on this and then I look at the code examples produced by AMD and there are just so many example. I just don't feel like I have the manpower to compete with AMD, Nvidia, Apple and Intel. I want my version to support all GPU backends, the CPU and the Cell. The OpenCL C compiler is not done but I was thinking about writing it for my master's thesis. But I don't know.....Any other open source developers out there with advice/tips on dealing with competition from corporations? Will they steal my stuff and not make it free source? Is it worth it to put effort into open source?

Hi, I am working on an OpenCL implementation sponsored by google summer of code. It is nearly done supporting the CPU and the Cell processor. This news has come to as a blow to me. I have struggled so much with my open source project and now a big company is going to come and trample all over me. boo hoo. http://github.com/pcpratts/gcc_opencl/tree/master

I clicked on a link from the site to one of their references and my virus checker went crazy. This site is fake.
