IWOCL 2026 marks the 14th anniversary of the annual gathering of the international community of OpenCL and SYCL developers, researchers, implementers, scientists and Khronos Working Group members to share best practice, and to advance the use and evolution of these Khronos open compute languages for programming heterogeneous platforms.
This pioneering workshop has been attracting an international audience of leading academic and industrial experts since 2013 and is the premier forum for the community to present, discuss and learn about applying OpenCL and SYCL to solve computationally-demanding problems across a wide range of application domains.

DESIGNED FOR OPENCL & SYCL DEVELOPERS
The Workshop Program
Once again we have a packed program planned including the latest technical talks, application case-studies, panel discussions, Khronos Work Group updates on OpenCL and SYCL, and a poster display spanning a wide range of topics. The full IWOCL 2026 program will be published in early 2026. Due to the quantity and quality of recent submissions, and the request for more time for informal discussion, the conference has again been extended to three-days.
All our sessions are aimed at developers looking to learn more about OpenCL and SYCL and we aim to provide developers a wealth of best practices and knowledge. IWOCL also provides ample opportunity to connect with other developers, vendors and ecosystem partners during the networking breaks, Q&A sessions, panel discussions, and during the official conference dinner and social evenings.
- The IWOCL 2026 program will be published in Q1 2026
