The wide adoption of SYCL as an open-standard API for accelerating C++ software in domains such as HPC, Automotive, Artificial Intelligence, Machine Learning, and other areas necessitates efficient compiler and runtime support for a growing number of different platforms. Existing SYCL implementations provide support for various devices like CPUs, GPUs, DSPs, FPGAs, etc, typically via OpenCL or CUDA backends. While accelerators have increased the performance of user applications significantly, employing CPU devices for further performance improvement is beneficial due to the significant presence of CPUs in existing data-centers. % and other setups.
