Data Parallel C++: the oneAPI Implementation of SYCL*

Cross-Architecture

  • SYCL* is an alternative to single-vendor proprietary accelerator programming languages 
  • Allows code reuse across hardware targets (CPU, GPU, FPGA) and supports custom tuning for a specific platform
  • SYCL is a Khronos* standard that adds data parallelism and heterogeneous programming to familiar and standard ISO C++

Discover SYCL

An Implementation of SYCL

  • DPC++ is one of the compiler implementations

Intel® oneAPI DPC++/C++ Compiler

Companion Intel® oneAPI DPC++ Library

 

Open Community Project

  • oneAPI is an open source LLVM* technology implementation of SYCL
  • API extensions are driven by open and cooperative community development
  • Once proven, these enhancements are proposed to the parent specifications (C++ or SYCL) for implementation
