Energy efficiency in HPC
What is actually going on, energy-wise, in a supercomputing centre, and how can we compute more energy-efficiently? An FAQ for everyone who is not particularly keen on launching data centres into space, as Captain Musk is planning to do.
MUSICA is online
Austria’s most powerful supercomputer is now online, and companies can use it: MUSICA (Multi‑Site Computer Austria) was officially inaugurated on 3 July 2026. With 45.11 petaflop/s and 1,088 NVIDIA H100 GPUs, it is among the 100 fastest supercomputers in the global TOP500 ranking and delivers more than eight times the performance of Austria’s existing HPC systems VSC‑4 and VSC‑5 combined. It supports both large‑scale simulations and modern AI workloads.
Supercomputer against polarisation on social media
Computer scientist Stefan Neumann and his team study social media networks to understand how algorithms influence users’ opinions: on the ASC, they simulate how filter bubbles and polarisation emerge – and what options there are for influencing this development. What we then do with the results? That is something we, as a society, have to decide for ourselves, says Stefan in this interview. Fascinating.
When deserts fly: an Innsbruck scientist explores a hidden force in the sky
We know flying carpets from fairy tales – but flying deserts are real: thick layers of hot desert air that travel all the way to Europe. Once there, they settle like a lid over the atmosphere and influence our weather. Atmospheric scientist Fiona Fix-Hewitt is researching this little-known phenomenon using supercomputing and millions of virtual balloons. In this interview, she talks about the dynamics of the atmosphere and life with HPC systems.
Lightning meets AI
Isabell Stucke is on the trail of a very special weather phenomenon: upward lightning, bolts that shoot up from wind farms into the clouds and can cause significant damage. In this interview, the atmospheric scientist explains how she uses AI and supercomputing to get to the bottom of lightning risks.

CUDA: strengths, limits and the best alternatives
Graphics processing units (GPUs) have become essential for artificial intelligence, simulations and data analysis. The vast majority of GPUs in use worldwide are made by NVIDIA – and on almost all of them runs the company’s own platform, CUDA. But what exactly hides behind those four letters, where does CUDA have the edge, and what alternatives exist?
