Recent Webinars

OpenMP 6.0 Part 1: New Host-side Features and Enhancements

Just before the end of the 2024 we hosted the 31st POP webinar with Dr. Christian Terboven and Dr. Michael Klemm. Part 1 of this two-part OpenMP 6.0 webinar series focussed on the key updates including the introduction of free-agent threads, the taskgraph construct and the concept of iteration within tasking contexts. Listeners also learned about the improvements in base language support and loop transformation capabilities.

The recording and the slides can be found here.

OpenMP 6.0 Part 2: New Device Offloading Features

Part two of the OpenMP 6.0 webinar series was held on the 18th of February. In this webinar Christian Terboven and Michael Klemm continued to explore the new features of OpenMP focussing on accelerator programming. The session concluded with an engaging Q&A session for the attendees.

ZeroSum: User Space Utility for Monitoring Process, Thread, OS, and HW Resources, including GPU Utilization

High Performance Computing (HPC) systems are large, heterogeneous, sophisticated – and are therefore so complicated that they are difficult to use efficiently. In his webinar on the 28th of March Kevin Huck introduced ZeroSum a user space library, which monitors the application threads, MPI communication, and the hardware resources assigned to a user and indicating whether they are using their finite allocated compute time effectively.

The recording and the slide presentation can be found here.
