Vulkan isn't suitable for this, with most GPGPU compute stacks not accommodating Vulkan's SPIR-V dialect, including Khronos's own SYCL.
Note that this wave of datacenter GPUs doesn't support OpenGL or Vulkan, because they either don't have rasterizers at all (AMD MI250X) or have them only on two TPCs for basic SW compat and don't expose OGL/Vk via virtual functions (NVIDIA).
As such, better OpenCL drivers are what you should ask for. But then AMD's OpenCL drivers are not exactly that great, and NVIDIA's have their own quirks.
