We are indeed interested in targeting AMD GPUs. There is a prototype backend available at https://github.com/JuliaGPU/AMDGPUnative.jl https://github.com/JuliaGPU/AMDGPUnative.jl and we are closely following the status of SPIR-V and Intel GPUs in LLVM. The focus on CUDA comes from the fact that most HPC systems for scientific computing are using Nvidia GPUs. That is finally slowly changing.
