ComputeCpp, the Codeplay implementation of SYCL, offers experimental support for NVIDIA GPUs using OpenCL. NVIDIA’s PTX, DPC++ (Intel’s SYCL implementation) offers the opportunity to add full support for NVIDIA GPUs integrated into the LLVM compiler without going through OpenCL. Codeplay has open sourced the experimental phase of their implementation that enables SYCL developers to target NVIDIA GPUs.
