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).

CUDA* to SYCL Catalog

 

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.

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 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 that include GPUs
  • Buffers and accessors
  • Queues
  • Data parallel kernel “parallel_for”

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
