Today I would like to describe one way to build a scalable and frictionless benchmarking pipeline for Android native libraries, aiming to support different benchmark and device variants. It is for open source projects, so it composes public services, commonly free under such conditions. The ingredients are cloud virtual machines for building, local single board computers (e.g., Raspberry Pi) for hosting Android devices and executing benchmarks, a Dana server for keeping track of benchmark results of landed changes, and Python scripts for posting benchmark comparisons to pull requests. A Buildkite pipeline chains them together and drives the full flow.

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.
