I have an AVX compatible CPU. The header files for NVIDIA OpenCL bundled with the latest Ubuntu 12.10 don’t compile with GCC 4.7.2 using the ‘-march=native’ compile flag because the ‘/usr/include/nvidia-current/CL/cl_platform.h’ header includes gmmintrin.h instead of immintrin.h.
I hope you will be adding OpenCL 1.2 support soon. As it is I am offloading some computations to the CPU namely because I can’t invoke popcount in the NVIDIA OpenCL implementation although it works fine in the CPU implementations from either Intel or AMD and your hardware supports it internally.
I don’t understand why it is taking so long for NVIDIA to release a product compliant with OpenCL 1.2 given that even when we had Cg you still provided top notch GLSL support. Some of us aren’t interested in using a single-vendor programming language which probably won’t be in use a decade from now.
