Join OpenMP for SC’21!
We have a full line-up of activities for you, including a BOF, Tutorials, pre-recorded Booth Talks, a Book Drawing, and Giveaways. We will add content here as the schedule tightens up, so bookmark this page and keep coming back to learn more! In the mean time, be sure to register for SC’21!
Look for us on the show floor in Booth #919!
Not traveling yet? That’s okay: we’ve tried to make as much of our SC’21 offerings available to virtual attendees as we can. Learn more about that in each section below.
OpenMP Booth Talks
OpenMP Booth Talks are short presentations about specific tools, tips, or applications of OpenMP, typically delivered live in our booth.
Attending SC virtually? In order to practice safe social distancing in the booth this year, our popular annual booth talk series will be 100% virtual.
Below is the list of the booth talks we have lined up so far for this year with links to videos and presentation PDFs.

OpenMP Tutorials
SC tutorials are a great way to get a deep dive on OpenMP. Times and registration links are listed below. All of our tutorials are available virtually.
Mastering Tasking with OpenMP
Mastering tasking requires a change in the way developers reason about the structure and parallelism of their code, including the use of composable parallel software blocks and parallelization of irregular algorithms. This tutorial examines the tasking concept and features in detail and presents patterns as solutions to many common problems, focusing on performance aspects with extensive case studies and exercises.
You can connect to our remote servers during the tutorial, but the best option is for you to load an OpenMP compiler onto your laptop before the tutorial. Information about OpenMP compilers is available at openmp.org/tools.
- Date/Time: Sunday, 14 November 2021 | 8am – 5pm CST
- Speakers: Christian Terboven, Michael Klemm, Xavier Teruel

The OpenMP Common Core: A hands-on Introduction
OpenMP started as a simple API, but over the years it has become more complex. This tutorial will help you master the 21 items that OpenMP programmers use the most: the “OpenMP Common Core.” We focus on C, but all exercises are available in both C and Fortran. We expect students to use their own laptops (Windows, Linux, or macOS).

Advanced OpenMP: Host Performance and 5.1 Features
With the increasing prevalence of multicore processors, shared-memory programming models are essential. This tutorial explores OpenMP parallelization strategies for scalability and performance for multicore architectures. We focus on performance aspects, such as data and thread locality on NUMA architectures, false sharing, and exploitation of vector units. All topics are accompanied by extensive case studies and we discuss the corresponding language features in-depth, including recent additions of OpenMP 5.0 and 5.1 and comment on developments targeting OpenMP 6.0.

Programming your GPU with OpenMP: A hands-on Introduction
OpenMP originally focused on symmetric multiprocessors, but modern hardware has evolved. This tutorial is for attendees who already know the fundamentals of OpenMP and want to learn how to use the target directives to map code and data onto GPU devices. We expect students to use their own laptops (Windows, Linux, or macOS).

BOF: OpenMP Offloading and the 5.2 API
This year the OpenMP ARB will be releasing version 5.2 to refine the OpenMP directives and reduce the complexity of the specification. At this year’s BOF we will highlight some of the most exciting new features in the new release, along with the latest developments by OpenMP vendors and successes of OpenMP users. Attendees will get first-hand information from OpenMP ARB members and have a chance to engage with the representatives of the OpenMP ARB in an interactive discussion, ask questions, and provide their feedback as users. We want to hear what you think!
Our usual BOF format is adapted to encourage interactivity from a virtual audience. We will use online survey tools to get live feedback that we will integrate into the discussions with our virtual panelists. We will also allow virtual participants to ask questions and provide feedback both in written and in a call-in format.
- Date: Wednesday, November 17
- Time: 5:15 pm (CST).

Exhibitors Forum: OpenMP API Version 5.2 Update and Outlook
Since its creation in 1997, the OpenMP API has become the standard programming model for multi-threading in HPC applications and has enabled many scientific discoveries by making it easy for scientists to exploit the power of modern computers. The OpenMP API uses directives to augment code written in C/C++ and Fortran with parallelization, vectorization and offload information for the compiler. OpenMP has become a programming model that supports modern task-based programming as well as heterogeneous programming for offload devices such as GPUs, or even FPGAs.
In the week before SC21, the OpenMP Architecture Review Board plans to release Version 5.2 of the OpenMP API specification. This version is not only an incremental refinement of Version 5.1 of the specification, it also restructures the specification document and makes existing features more consistent in their syntax and semantics.
In this presentation, we will review the changes of version 5.2 of the OpenMP API and describe how they extend the current features of the OpenMP API. We will also provide an outlook on the future of the OpenMP API.
- Length: This is 30-minute session
- Date: Tuesday, November 16
- Time: 3:30 pm CST
- Location: Room 263 and virtual
- Presenter: Michael Klemm, OpenMP CEO
