Join us in St. Louis for SC25!
Join us in St. Louis for SC25!Supercomputing 2025 will be in St. Louis, November 16-21. We will have a BOF, two Tutorials, a Book Drawing, and scheduled sessions where you can meet with experts in the booth.
Find us on the show floor in Booth #911
Come to our booth to talk with OpenMP API experts, enter our book drawing, pick up your OpenMP 6.0 Reference Guide, or just take a break in our comfy seating and hang out with us at the show.
BOF: Key Features Coming to OpenMP API Version 6.1
The OpenMP Architecture Review Board (ARB) released the OpenMP API version 6.0 shortly before SC24 and releases new versions every 2-3 years. This year, between releases, we will share headline features planned for the OpenMP API version 6.1 ahead of its release before SC26. Feature champions from the OpenMP ARB and Language Committee will highlight OpenMP features in development, and attendees can provide their input the standard ahead of the release. The BOF will have short lightning talks, and discussion rounds will give participants amble opportunity to interact with OpenMP experts, ask questions, and provide feedback. Vendor representatives will discuss support and timelines for OpenMP features.
This BOF this year will be run by active OpenMP members Tom Deakin, Bronis R. de Supinski, Tom Scogland, Stephen L. Olivier, and Johannes R. Doerfert.
- Wednesday (19 Nov), 5:15 pm CST, Rooms 231-232

OpenMP Tutorials
SC tutorials are a great way to get a deep dive on OpenMP. Times and registration links are listed below.
Mastering OpenMP Tasking: from Start to Free-agent Tasks
OpenMP provides a standard, easy-to-use model to program multiprocessors and is supported by all major compilers. The maturity and industrial-level support make it a natural selection for many companies and supercomputing centers to parallelize their applications for shared-memory machines. This tutorial will improve the programming skills of the attendees by providing performance and scalability recipes to improve the performance of OpenMP tasking applications. It will teach the use of the recent tasking-oriented additions to OpenMP, ranging from OpenMP 5.2 to to OpenMP 6.0, and it will gather input from experienced users about the issues that most limit their use of OpenMP tasking.
This tutorial is intended for attendees who have a general knowledge of computer architecture concepts (e.g., SMT, multi-core, and NUMA); a basic knowledge of OpenMP; and a good knowledge of either C, C++, or Fortran.
All presenters are long-time members of the OpenMP Language Committee and include the head of the OpenMP Language Committee and the CEO of the OpenMP organization.
- Sunday (16 Nov), 8:30am – 12:00pm CST — Room 125
- Speakers: Christian Terboven, Michael Klemm, Stephen Olivier, Bronis de Supinski

Programming your GPU with OpenMP: A Hands-on Introduction
OpenMP 1.0 was released in 1997 when the primary concern was symmetric multiprocessors. A modern platform is often a heterogeneous system with CPU cores, GPU cores, and other specialized accelerators. OpenMP has responded by adding directives that map code and data onto a device. We refer to this family of directives as the target directives. In this hands-on tutorial, we will explore these directives as they apply to programming GPUs. We assume attendees already know the fundamentals of OpenMP so we can focus on deeply understanding the target directives and their use in complex applications. We expect students to use their own laptops (with Windows, Linux, or macOS) to connect to remote servers with GPUs, but the best option is for students to load an OpenMP compiler onto their laptops before the tutorial. Information about OpenMP compilers is available at openmp.org/tools.
- Monday (17 Nov), 1:30pm – 5:00pm CST — Room 121
- Speakers: Tom Deakin, Tim Mattson
