U.S. and South Korean RISC-V researchers managed to make Nvidia's CUDA code compatible with non-Nvidia hardware. It is quite the achievement considering AMD and Intel have not yet pursued such a solution. The RISC-V-based Vortex GPGPU essentially translates CUDA code into OpenCL instructions through the RISC-V library.

If nothing else it's a good proof of concept and bodes well for the future of risc-v.
