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 #HPC #MPI

EVITA presented at the All-Hands in Tallinn! 🚀 We shared our mission, training framework, and ideas for collaboration with NCCs, sparking great discussions. Thanks to all for the active exchange — excited to build on this together! #EuroHPC #EVITA #EuroCC #CASTIEL #HPC #Training #Collaboration

Striving for peak performance? Need some help? 🎓 The first autumn training events are online - ASC-Linux, ASC-Intro, C++, CUDA, DL, MPI, and more to come 🎓 Students at Austrian universities can earn ECTS asc.ac.at/training/ events.asc.ac.at/category/4/ 📸 Peak performance - greatings from Madeira

Great to see this article! We’re also happy to have @claudiablaas.bsky.social supporting us with teaching, running climate model simulations on an HPC system, and guiding us through ASC. Her involvement is certainly an inspiring example for our female students.

I recently gave an interview how the initiative Women in HPC drives change. #HPC #WHPC

“Be bold, believe in your potential, stay curious.” #HPC expert Claudia Blaas-Schenner on why #diversity is essential for #supercomputing – and how the initiative Women in HPC drives change. Read more: eurocc-austria.at/en/blog/be-b... @claudiablaas.bsky.social @womeninhpc.org #WomenInTech

This week in ✨Foundations of #LLM Mastery ✨Fine-tuning on one GPU ✨Fine-tuning on multi GPUs Martin and Simeon rocked the floor with cute Llamas and great explanations: 🦙 LLM parallelization how to chop up a Llama 🦙 LLM evaluation how to take a Llama‘s measurement When #AI meets #HPC

Looks like the course material is also all open. Good examples to show how all the pieces can fit together in practice: gitlab.tuwien.ac.at/vsc-public/t...

It’s #RAG time in our course series ✨Foundations of #LLM Mastery ✨Retrieval Augmented Generation Today, Thomas showed how to build a RAG system from scratch and explained how to overcome the challenges and use RAG effectively 🚀 ✨https://events.asc.ac.at/e/LLM-rag-2025-08 When #AI meets #HPC

The #ASC training is back with the summer edition of our course series ✨Foundations of LLM Mastery Yesterday, Simeon talked about ✨Prompt Engineering Essentials ✨ events.asc.ac.at/e/LLM-prompt... When #AI meets #HPC @asc.ac.at @eurocc-austria.at #AI:AT #LLM

⚡ The Cray-1 (1976) was the fastest computer in the world: 80 MHz, over 5 tons, and shaped like a futuristic lounge chair. Today, you carry more power in your pocket. #FunFactFriday #TechHistory #CommPath #ThenVsNow #HPC

In June we supported the inaugural Leh Indian Glaciology Summer School (LIGSS-2025) in Ladakh, India with computing resources. Blog post: asc.ac.at/news/2025/ne... #HPC #ASC #ASCtraining

Earlier this month we attended the kick-off meeting of the EVITA project aimed to strengthen #HPC training landscape in Europe. Read about the launch and the goals we're working toward: asc.ac.at/news/2025/ne... @evitahpc.bsky.social @bsc-cns.bsky.social @eurohpc-ju.bsky.social @tuwien.at

In the few days I have between jobs, I wanted to share an unvarnished perspective on what I've learned after spending three years working on supercomputing in the cloud. It's hastily written and lightly edited, but I hope others find it interesting: blog.glennklockwood.com/2025/07/less... #HPC

The bootcamps are over for now, but we'll continue our collaboration with #NVIDIA and #OpenACC_org for the AI Hackathon - for teams of 3+ & AI project - application deadline is 5 August Blog: www.openhackathons.org/s/article/Bo... AI Hackathon: events.asc.ac.at/e/AI-hackath... When #AI meets #HPC

Today we had our last big bootcamp for this season – we let 110 participants dive into intermediate to advanced topics on #LEONARDO supercomputer in the Profiling AI Software Bootcamp events.vsc.ac.at/e/AIprofilin... When #AI meets #HPC 🧵

Vienna Scientific Cluster (VSC) is now Austrian Scientific Computing (ASC)

We had a very successful #EVITA Kick-Off Meeting this week – thanks to #BSC for hosting the meeting and all partners for the constructive collaborartion! EVITA – EuroHPC Virtual Training Academy – aims to build a unified, inclusive, and future-ready training framework for HPC+ across Europe.

Today and tomorrow we have the #EVITA Kick-Off Meeting at #BSC. We also got to see MareNostrum5 and the two quantum computers available at BSC. @evitahpc.bsky.social @bsc-cns.bsky.social

A little sightseeing before …

Fly away – mountains – sea – containers Any guess about the mountains and final destination?

It‘s the end of the semester! It‘s excursion time! Today I took my InterMaths students on a guided tour to finally see the hardware they were using during the labs. @vscluster.bsky.social

Our #GPU bootcamps reached the next level – Multi-GPU 🚀 Last week we had 120 participants in Zoom, on Slack, and on the GPUs of #Athena (Cyfronet) – it’s great to see so much interest in #HPC Multi-GPU Programming Bootcamp events.vsc.ac.at/e/Multi-GPU-... 🧵

Is training scalable? With the right partners and a little parallelization definitely yes! A while ago we conducted a quite large ✨AI4science✨ boocamp with 210 participants – 2 very intense half days in Zoom, on Slack, and on the GPUs of 3 HPC systems – absolutely amazing 💯 When #AI meets #HPC 🧵

Big resource providers should make the production emission part of the procurement! #Sustainability must be a key element from now on! @cflorina.bsky.social @unibas.ch #CarbonNeutral #HPC #pasc25

Cynical mode: “sovereign” was a clever way to make each nation buy its own cloud/ai infra instead of using others. Visionary: sovereign makes each nation think “what if” & ensure it controls its own data. Provocative: nations don’t own data anyway - companies (often multinational) or people do.

Goodby Hamburg – with a very short sightseeingtour to Elbphilharmonie 📸 #Elbphilharmonie #Hamburg

So happy to co-lead together with Maria-Ribera Sancho from BSC #EVITA WP2 "Definition of EVITA Competence and Qualification Framework (CQF) and its Integration into the European #HPC Ecosystem" and contribute to the other WPs of the project 🎓 @vscluster.bsky.social @tuwien.at @bsc-cns.bsky.social

Last day, last keynote at #ASHPC25 When data are big in the „wrong“ direction: identifying compact and informative distance measures in high-dimensional feature spaces by Alessandro Laio (SISSA & ICTP) When #AI meets #HPC

At #ASHPC25 sharing the details of their #AIFactories 🏭 #AI:AT – Austria Markus Stöhr (ACA) 📸 🏭 #SLAIF – Slovenia Jan Jona Javoršek (IJS) 🏭 #IT4LIA – Italy+ Orlenys Troconis (CINECA) When #AI meets #HPC

MUSICA is not an #HPC system that can sing and dance, it‘s: MUlti-SIte Computer Austria Infrastructure --> power & cooling Delayed delivery Acceptance --> almost all GPUs had to have their thermal transfer pads replaced --> Weka storage needs better CPUs (will be exchanged with 64 core versions)

Every conference needs a bit of chaos, at #ASHPC25 we decided to go with quantum chaos and a keynote by Jan Šuntajs (IJS) on High performance computing #HPC at the boundaries of quantum chaos Why? – #AI answers: "It reveals deep rules of nature and helps us build better quantum technologies."
