Happy to host EuroMPI & IWOMP 2026 from 7-9 October 2026 in Vienna.

Due to the high demand we‘ll do a re-run on 24 April 2026:

Participants and trainers of „Hands-on Explainable AI (XAI), 20 February 2026, online" – 46 persons (from the 118 in the Zoom meeting) are on the picture.

Yesterday‘s course „Hands-on Explainable AI (XAI): From Data Understanding to Model Interpretation“ was a blast.

A big applause to our lecturer Anahid Wachsenegger from AIT who did a great job in guiding 115 participants through the hands-on labs on the GPUs on VSC-5.

This week’s course

Hybrid Programming in HPC – MPI+X

was a joint training event within the EuroCC Project @eurocc.bsky.social by @sc-in-de.bsky.social & @eurocc-austria.at and the HPC centers @hlrs-hpc.bsky.social & @asc.ac.at & @rrze.de / @georghager.bsky.social

Hands-on labs at the „Hybrid Programming in HPC – MPI+X“ course at HLRS

Looking out of the course room „Rühle Saal“ at HLRS – HLRS get‘s a new building to host their future HPC systems

In-person participants in the hybrid „Hybrid Programming in HPC – MPI+X“ course at HLRS

I‘m always happy to come to HLRS / Stuttgart for our training collaboration – „Hybrid Programming in HPC – MPI+X“ this time together with Tobias Haas and Georg Hager.

Engaged participants onsite & online, good vibes in the room, and a huge construction site outside for the new HLRS building.

#HPC

Excellent reads – paper, essay, and blog post.

As we are starting procurement of our AI Factory Austria #AI:AT system soon, I especially enjoyed Glenn’s @glennklockwood.com perspective „of an HPC-turned-AI infrastructure practitioner“.

When #HPC meets #AI

Access to advanced computing resources is getting easier:

The #EuroHPC #Federation Platform is set to federate all AI factory supercomputers, HPC systems, and quantum systems across Europe.

Today we had very special guests at #ASC - a group of students doing climate modelling with @blazgaspa.bsky.social at @univie.ac.at got to see the hardware they were using during the past semester 🌱🌍🌎🌱

Want to have a look at the material:

I fully agree. It seems bluesky is not working properly for HPC anymore…

"Foundations of LLM Mastery: Fine-tuning on multi GPUs, 27 November 2025, online" LLM parallelization - how to chop up a Llama

"Foundations of LLM Mastery: Fine-tuning on multi GPUs, 27 November 2025, online" LLM evaluation - how to take a Llama‘s measurement

This week in Foundations of #LLM Mastery:

✨Fine-tuning on one GPU
✨Fine-tuning on multi GPUs

Martin and Simeon are back with their cute Llamas and great explanations:

🦙 LLM parallelization
how to chop up a Llama
🦙 LLM evaluation
how to take a Llama‘s measurement

As said before:

Very well deserved - congratulations to the team for making 1.25 km Global Earth System Simulations possible 👏

Jupyter NBs for the labs are available here:

It does and I had several images with communication across chips. This was just the nicest image it gave me 😉

Parallel programming with MPI – a group of people sitting on a CPU – MPI processes are just like humans talking to each other – this is what Copilot gave me (back in April 2025) to depict MPI communication

Could not come to SC25 because I had to teach:

🎯 Parallel Programming with #MPI
🎯 One of the most iconic tools in #HPC
🎯 Don’t work hard – work in parallel 🚀

MPI processes are just like humans talking to each other – this is what Copilot gave me (back in Apr 2025) to depict MPI communication:

How can you influence LLMs? With increasing complexity, cost, quality: => From your hand-held devices... 1. Prompt Engineering 2. RAG (Retrieval Augmented Generation) 3. Fine-tuning 4. Train from scratch => ... to supercomputers / hyperscalers

Our Foundations of LLM Mastery course series has started this week with

✨Prompt Engineering Essentials
✨ Retrieval Augmented Generation

Fine-tuning on one(multi) GPU(s) with the 🦙Llamas🦙 will follow in two weeks - there are still a few seats available!

Image from "Shared-Memory Parallelization with OpenMP, 3-4 November 2025, online"

This week we've moved parallelism to a new level – our DL course and our OpenMP course were done in parallel – which picture is your favorite?

Next week, we'll start with the November edition of our famous LLM course series – there are still seats available!

Promotion image for "ASC-Linux + ASC-Intro, October 2025, online"

The new training season has started already a while ago and we've already covered a lot: #HPC Literacy, C++, #AI Hackathon, Trustworthy AI Webinars (in German and English), How to Run AI Workflows in MATLAB, CUDA, Debugging and Optimizing with Linaro Forge... – it's been a busy October here at #ASC.

Hey @corepointer.graz.social.ap.brid.gy 👋

Yes, that‘s what they say. Will be published on the EuroHPC website.

I got featured by EVITA.
Happy to contribute to and improve European HPC training through EVITA 🚀

Amazing - just 1.25 kilometres - what a fantastic achievement 👏

What are you doing this week? I am spending my afternoons and nights as a remote participant at #MPIforum and #EuroMPI + #IWOMP
