OpenMP Tutorials

SC tutorials are a great way to get a deep dive into the OpenMP API.

Mastering OpenMP Tasking: Hands-on

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.

• Date: Monday, Nov. 16 (Room TBD)
• 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.

Videos of OpenMP Tech Talks

OpenMP Tech Talks are short presentations about specific tools, tips, or applications of OpenMP. We will post the SC26 OpenMP Booth Talks here as soon as they are available.

You can check out previous year’s videos (previously called “Booth Talks”)  here: 2025, 2024, 2023, 2022, 2021, 2020.

Book Drawing: Enter for a chance to win an OpenMP book!

We will have a drawing for a free OpenMP book at the end of each day during the SC25 Exhibit, Monday-Thursday, November 16-19. Enter the drawing in our booth during regular show hours, then you will be entered into the drawing for that day. Full details, rules, and eligibility requirements are below.

The winner must be present at the drawing to win. The drawing times and daily entry deadlines are (all time in local St. Louis CST):

• Monday, Nov 16 at 8:30 pm
• Tuesday, Nov 17 at 5:30 pm
• Wednesday, Nov 18 at 4:45 pm (After the drawing, head to the BOF!)
• Thursday, Nov 19 at 2:30 pm

Choose your prize: When their name is drawn, the winner will be asked to select from among the books listed below, which we will ship to their address:
