Since early 2022, the Accelerated Devices lab has been involved in the OpenGPT-X project. ¹ OpenGPT-X trains large language models to enable new data-driven business solutions and specifically address European needs. As of January 2025, the project has published its main results and is set to wrap up in early 2025.

From November 17th to 22nd, 2024, HPC professionals and researchers gathered in Atlanta, Georgia, for the Supercomputing Conference 2024. We presented a paper at the 2024 International Workshop on Performance, Portability, and Productivity in HPC where we introduced CARAML, a reproducible AI benchmarking framework, and jpwr, a custom energy assessment module. The presentation slides are embedded at the bottom.

At the end of 2023, the contract was signed to build JUPITER, a new European supercomputer and the first to reach 1 ExaFLOP/s HPL performance.

In November of 2022, I created a table comparing GPU programming models and their support on GPUs of the three vendors (AMD, Intel, NVIDIA) for a talk. The audience liked it, so I beefed it up a little and posted it in this very blog.

The Supercomputing Conference 2023 took place in Denver, Colorado, from November 12th to 17th. For the Women in HPC workshop, we submitted a paper, which focused on benchmarking different accelerators for AI. The paper was accepted and I was invited to hold a lightning talk to show the work, spun off our OpenGPT-X project.

Together with our colleagues from Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and in collaboration with HIDA and OpenHackathons, we hosted the Helmholtz GPU Hackathon 2023 in Jülich in May. I’ve blogged about the event for the Zweikommazwei blog of Forschungszentrum;
