Used to leave a buffer space for the main kernel. Set this to a small integer value (like 1) if needed.
-O2 Optimize even more. GCC performs nearly all supported optimizations that do not involve a space-speed tradeoff. The compiler does not perform loop unrolling or function inlining when you specify -O2. As compared to -O, this option increases both compilation time and the performance of the generated code.
Include path to NVIDIA OpenCL library header
