A unified programming model offers enterprises and OEMs a cost-effectively way to take advantage of the growing diversity of processor platforms, letting companies share their source code investment across vendors and architectures. Enter oneAPI from Intel, which aims to revolutionize application development through a unified, open development model to simplify programming across processors. Intel built upon C++, and SYCL from The Khronos Group had some really good constructs that they thought provided a very good starting point. Intel extended and improved it to achieve the goals that they wanted to achieve. Most of the DPC++ extensions will eventually be synced upstream into SYCL.
