Vulkan is designed to be both a graphics and compute API. However, there is no formal definition of the compute subset from the Khronos group, the industry consortium behind Vulkan. The unified specification of Vulkan does not help here either as it contains everything, both graphics and compute. Unlike the complicated graphics subset, the compute subset is actually quite straightforward and clean. So in this blog post I try to explain what Vulkan compute is, from my point of view.
