Conference Updates

The International Workshop on OpenCL

IWOCL is the annual gathering of international community of OpenCL, SYCL and SPIR developers, researchers, suppliers and members of the Khronos Working Groups to share best practise, and to promote the evolution and advancement of the standard.  The meeting is open to anyone who is interested in contributing to and participating in the community and is the premier forum for the presentation and discussion of new designs, trends, algorithms, programming models, software, tools and ideas relating to OpenCL.  Additionally the conference provides a formal channel for community feedback to the Khronos Group the industry body responsible for the standard.


Northeastern University Welcomes IWOCL 2019 to Boston

Northeastern University is pleased to welcome the 7th Annual International Workshop on OpenCL to Boston in 2019.  Boston is a educational leader and high-tech hub in the US, as well as being one of the most diverse in terms of culture and history.  As Ralph Waldo Emerson noted: “Boston is the one place in America where wealth and knowledge of how to use it are apt to coincide.”  May is a beautiful time to visit Boston and the New England area, with average temperatures around 66F/19C.  We welcome you to our campus and our city, and hope you will spend the time to experience this great region of the US.

DHPCC++ 19 in Boston

IWOCL is partnering with DHPCC++ to host the 4th workshop on Distributed & Heterogeneous Programming in C/C++.

We are excited that DHPCC++ will again be co-located with IWOCL and it’s an excellent opportunity to bring together experts in heterogeneous programming. DHPCC++ gives us a chance to learn about new projects, research and frameworks for developing high performance software using C and C++ for parallel systems. It is also designed to generate discussion and debate on the future of C and C++ programming in heterogeneous systems. We look forward to meeting the high performance community in Boston.

Welcome to the 7th International Workshop on OpenCL


IWOCL began after a chance conversation between myself and Ben Bergen from Los Alamos in 2012. We were lamenting the lack of user-focused workshops for the growing OpenCL community, and decided to run one to see if it garnered much interest. With just three months’ notice, we ran the first IWOCL at Georgia Tech in Atlanta, and over 40 people showed up. Now in its seventh year, IWOCL attracts a wide range of OpenCL experts, from across industry, academia and vendors and has become the premier venue to meet others using OpenCL to solve challenging problems, whether in embedded systems or in high performance computing. It’s also the ideal opportunity to meet with, and give feedback to, the people developing the OpenCL standard itself, as many of the Khronos OpenCL working group members attend IWOCL each year. In short, if you’re interested in OpenCL, make sure you attend IWOCL 2019 in Boston!

About OpenCL and Khronos

OpenCL – The Open Standard for Parallel Programming of Heterogeneous Systems

OpenCL (Open Computing Language) is the open, royalty-free API standard for cross-platform, parallel programming of diverse processors found in personal computers, servers, mobile devices and embedded platforms. The API greatly improves the speed and responsiveness of a wide spectrum of applications in numerous market categories including gaming and entertainment titles, scientific and medical software, professional creative tools, vision processing, and neural network training and inferencing.

About The Khronos Group

The Khronos Group is an industry consortium creating open standards to enable the authoring and acceleration of parallel computing, graphics, vision and neural nets on a wide variety of platforms and devices. Khronos standards include OpenCL, SPIR-V, SYCL and Vulkan. Members of Khronos are enabled to contribute to the development of Khronos specifications, are empowered to vote at various stages before public deployment, and are able to accelerate the delivery of their cutting-edge accelerated platforms and applications through early access to specification drafts and conformance tests.
