Tutorial Name: Let us SYCL

Summary: SYCL (pronounced ‘sickle’) programing standard is royalty-free, template based, cross-platform abstraction, targeting heterogeneous computing architecture with a host connected to various types of accelerators, typically GPU, CPU, and FPGA. SYCL enables code written in a “single-source” style using completely standard C++, where C++ template functions can contain both host and device code to construct complex algorithms and then re-use them throughout their source code on different types of data. This tutorial aims to teach you the fundamentals of SYCL through the explanation of a simple application.



  • Memory Model
  • Execution Model (ND-Range, Work groups, Work Items)
  • SYCL Queues
  • Manage Data in SYCL Using Buffers
  • Control Device Execution
  • Compute Kernels and Buffers
  • Write Your First SYCL Program
  • SYCL 2020 USM
  • SubGroups
  • Simplified Reduction


Expected Outcome:

This tutorial is for programmers who already have a decent understanding of C++ and parallelism.

Teaching C++ and parallelism is hard, and many materials already exist. There’s far less information on SYCL itself so that is this tutorial’s focus.
