Heterogeneous Modern C++ with SYCL 2020 - Michael Wong, Nevin Liber, Tom Deakin & Gordon Brown

--- Heterogeneous programming in C used to be hard and low-level. Today, Khronos SYCL for Modern C works with different libraries, ML frameworks and Standard C code on top of template libraries with lambda functions that separate host and accelerate device code in a single source, but still enables separate compilation of host and device code. The device SYCL compiler may employ kernel fusion for better performance and the host CPU compiler can be any C compiler, from clang, gcc, VS C , or IBM XL compiler. SYCL enables accelerated code to pass into device OpenCL compilers or other backends to dispatch to any variety of devices. This talk from members of the SYCL community will talk about highlighted features from the latest SYCL 2020. SYCL 2020 is released after 3 years of intense work with significant adoption in Embedded, Desktop and HPC markets. It offers improved programmability, smaller code size, faster performance and is
