Introduction GPUs are formidable parallel machines, capable of running thousands of threads simultaniously. They are excellent for embarassily parallel algorithms, but are quite different than the ones on the CPU due to the way GPUs work. You can’t just build and run an application. You need to interact with the GPU driver via one of several APIs available (CUDA, OpenCL, Vulkan, DirectX, OpenGL, etc), manage the device memory, organize the transfers between the host and the device, and dispatch ...
