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

Learn the Basics of SYCL

SYCL is an open alternative to single-architecture proprietary languages. It allows developers to reuse code across hardware targets (CPUs and accelerators such as GPUs and FPGAs) and also perform custom tuning for a specific accelerator. These code walkthroughs introduce you to basic principles and practices of SYCL programming. To continue learning about SYCL and Intel’s integration of this new programming language into the Intel ® oneAPI toolkits, see More Ways to Learn. 

1. Concepts and Functionality

The Vector Add sample demonstrates oneAPI concepts and functionally using SYCL programming language. You will learn about:

  • Device selectors targeting different accelerators including GPU and FPGA
  • Buffers and accessors
  • Queues
  • Data parallel kernel “parallel_for”

Go to Code Walkthrough

2. Unified Shared Memory (USM)

The Mandelbrot Set is a program that demonstrates oneAPI concepts and functionally using the SYCL programming language. You will learn about:

  • Unified shared memory
  • Managing and accessing memory
  • Parallel implementation
