Hi everyone,

I have a Macbook Pro running OS X 10.6.8with a GT 330M.

First, I have a compilation problem :

Seond, when trying to use the pre-compiled binaries I get this:
./HelloArgon
OpenCL internal error: [CL_INVALID_BUFFER_SIZE] : OpenCL Error : clCreateBuffer failed: No device in the context supports the requested allocation size (-1430580672 bytes)!
EXCEPTION: Error creating array sigmaEpsilon: clCreateBuffer (-61)

The reference implementation seems to work. I can't test the CUDA version as the drivers for 10.6 are outdated.

So, is it working at all on Snow Leopard ?

Thanks
