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.

Location
—--------------------------------------------------------
The conference is being hosted by the Technical University of Munich and will take place at the School of Computation, Information, and Technology in the beautiful city of Heilbronn, Germany. Heilbronn is approximately 1-hour north of Stuttgart by train.

Submission Types
---------------------------------------------------------
IWOCL welcomes the following four types of submissions.

+ Technical Presentations and Case Studies
+ Short Research Papers
+ Full Research Papers 
+ Posters 

The IWOCL proceedings are published in the ACM Digital Library. To ensure the quality of the program all submissions will undergo peer review by at least three members of the Program Committee comprising experts in OpenCL and SYCL.

Topics of Interest
---------------------------------------------------------
Topics of interest include, but are not limited to:

+ Scientific and high-performance computing (HPC) applications
+ AI and machine learning training and inferencing
+ Implementing OpenCL and SYCL
+ General performance optimizations
+ Compiler IR and optimizations for SYCL and OpenCL programs
+ Development tools and training materials, including debuggers, profilers, sample code and courses
+ HPC frameworks and supporting libraries
+ Novel uses of and extensions to OpenCL and SYCL
+ The use of OpenCL and SYCL on CPU, GPU, DSP, NNP, FPGA and hardware accelerators on mobile, embedded, cloud, edge, and automotive platforms

Submission Guidelines
---------------------------------------------------------
All presenters must attend in-person and register for the workshop at the prevailing discounted speaker/academic rate to present their material and to have their submission included in the published proceedings.

Technical Presentations & Case Studies
—---------------------------------------
Technical submissions require a 500-1,000-word abstract. Additional supporting materials may be submitted as a single pdf document. If the talk includes computational results, we encourage these to be included for review. Technical presentations will be listed in the ACM Digital Proceeding Front Matter, referencing the presentations and abstracts published on the IWOCL website, but the abstract will not be included in the ACM Digital Library. If accepted, talks will be presented at the conference.

Short Research Papers
—---------------------------------------
We solicit the submission of short unpublished academic/technical papers detailing original research related to OpenCL and SYCL. Please submit short papers for review, which should be between 3-4 pages. Short Papers will be included in the ACM Digital Library proceedings and should be prepared using the ACM *sigconf* template. If accepted, short papers will be presented at the conference.

Full Research Papers
—---------------------------------------
We solicit the submission of full-length unpublished academic/technical papers detailing original research related to OpenCL and SYCL. Please submit full papers for review, which should be between 8-12 pages. Full Papers will be included in the ACM Digital Library proceedings, and should be prepared using the ACM *sigconf* template. If accepted, full papers will be presented at the conference.

Posters
—---------------------------------------
Please submit a 500-1,000-word abstract of the poster. The abstract of the poster will be included in the ACM Digital Library proceedings, and should be prepared using the ACM *sigconf* template. If accepted, posters will be displayed at the conference. Authors are responsible for printing and bringing the poster to the venue for display. Maximum poster size: A0 portrait format.


Selection Criteria
---------------------------------------------------------
The IWOCL program committee will review submissions based on the following criteria.

+ Concept of the submission and its relevance and timeliness
+ Technical depth
+ Clarity of the submission
+ Research findings and results of your work
+ Your credentials and expertise in the subject matter
+ The Chairs and Program Committee members are also encouraged to submit their own papers, presentations, or posters to IWOCL. For these submissions, the peer review will be organised by a different Chair, and the submitter will have no involvement in the review process nor final decision of acceptance.

LaTeX Submissions
---------------------------------------------------------
For LaTeX submissions, ACM requires the source code of the document for proceedings. Please adhere closely to the supported LaTeX packages.
