hey, is it possible ? I got a Core2Duo and it says it were OpenCL capable.

But i never crunshed such a workunit, what´s wrong, or that did i wrong ?

And it were no iGPU unit...

Greetings

ok, i discovered something, on Collatz project they crunsh opencl with SSE4.1 functions, but will a Core2Duo do it ? Think not.

OpenCL is a computer language and an interface. It is one method to make any device that has an OpenCL compiler to do calculations.

I think that using SS(S)Ex.y or AVX(n) if available and hand tuned applications is much more productive on a device that has no real GPU (massively parallel SIMD).

Someone would have to make a SETI@home OpenCL CPU application in order for you to process a task that way.
I would guess Collatz chose to make their CPU apps in OpenCL to simplify writing them or the author is most familiar with that language.
All Intel Core Solo, Duo, 2 Duo, & 2 Quad CPUs are said to support OpenCL. I think Intel stated it along the lines of "All CPUs with SSE 4.1 or higher support OpenCL".
