Vulkan Compute – getting to a minimal example #GPU #Compute @BramStolk
Vulkan is a new generation graphics and compute API that provides high-efficiency, cross-platform access to modern GPUs used in a wide variety of devices from PCs and consoles to mobile phones and embedded platforms. The Khronos Group is a member-driven consortium that created and maintains Vulkan.
Bram Stolk, working on Photon Mapping experiments had gone from CUDA to OpenCL (for better compatibility) and then to Vulkan for even better compatibility. OpenCL was not cutting it anymore: abandoned by Apple, ignored by AMD. He found out when trying to use OpenCL on a mobile Ryzen iGPU under Linux, it didn’t work.
Vulkan can be intimidating: a lot of code must be generated just to set up an environment let alone do anything.
So Bram has created MinimalVulkanCompute, the minimal code to do Vulkan compute. It shows how to setup Vulkan to compute something on a GPU.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
