I'm using a MacBookPro with a GeForce 8600M GT (which, according to the NVIDIA site, supports OpenCL but not CUDA). OpenCLLink seems to install succesfully, and the low-level doc examples seem to work ok. It gags, though, on the higher-level functions, all with with the 'block size' message. The 8600M doesn't do doubles, only floats, so my current suspicion is that the high-level functions may be defined with features available only on the high-level chip sets. Regards, Fred Klingener
