Overview

Every CUDA program, no matter how large, is built from the same five moves: allocate device memory, copy input in, launch a kernel, copy output back, free what was allocated. SAXPY — y = a*x + y, scalar-times-vector-plus-vector — is small enough to show all five in one file without anything else getting in the way. The rest of this page walks the same file section by section.
