Vulkan Compute backends for numerical compute (as typified by both OpenCL and SYCL) are challenging, you can look at clspv https://github.com/google/clspv project for the nitty gritty details. The lowest-effort path so far is most likely via some combination of Rocm/HIP (for hardware that AMD bothers to support themselves) and the Mesa project's RustiCL backend (for everything else).
