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 and GPU) 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++

An Implementation of SYCL

  • DPC++ is one of the compiler implementations

Intel® oneAPI DPC++/C++ Compiler

Companion Intel® oneAPI DPC++ Library

 

oneAPI Initiative

  • oneAPI uses the SYCL framework and combines it with compilers, APIs, libraries, tools, and code samples.
  • Delivers a rich catalog of SYCL and oneAPI fully enabled applications with the achievable vision of ubiquitous multiarchitecture and multivendor computing.
  • It is governed by the Unified Acceleration Foundation (UXL).

Open Community Project

  • oneAPI is an open source LLVM* technology implementation with SYCL at its center.
  • 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.
