Same here. What else can you do to ship GPU acceleration to AMD and NVIDIA people?

The alternatives recommended here aren't even serious IMHO. I'd rather switch to CUDA and wait till Intel/AMD sort out a REAL compatibility layer than deal with those.

Unless I'm mistaken, HIP still requires a separate compile for either platform and what runtime do they expect end users to have exactly?! At least CUDA and OpenCL are integrated in the vendor drivers.

Vulkan compute with SPIR-V seems to be the only real solution, but even that is still very early. Sill waiting for proper OpenCL 2.0 support in NVIDIA drivers :P
