The Austrian-Slovenian HPC Meeting – ASHPC25 – took place in Rimske terme from 19 to 22 May 2025, continuing the tradition of annual meetings dedicated to High-Performance Computing (HPC), with its origins in Austria (2015) and joint Austrian-Slovenian meetings from 2021 onwards.
ASHPC25 brought together around 140 participants from 10 countries (Austria, Croatia, Czechia, Germany, Italy, Poland, Slovakia, Italy, Slovakia, UK, Slovenia, Austria, Germany, Italy, Poland, Slovakia, UK). The event aimed to bring together users and providers of large-scale computing resources in the fields of academic and industrial research and development.
The main part of the conference, which took place from 20 to 22 May, featured 5 invited speakers:
- dr. Dan Alistarh (ISTA, Austria)
- dr. Sam Hatfield (ECMWF, Great Britain)
- dr. Alessandro Laio (SISSA, Italy)
- dr. Erwin Laure (TUM & MPCDF, Germany)
- dr. Jan Šuntajs (IJS, Slovenia)
Their lectures addressed topical issues such as machine learning, energy-efficient algorithms, climate modelling, numerical weather prediction, molecular simulations, data analysis, parallel and distributed computing, and quantum physics.
The event received 60 submissions, more than half of which were presented innine thematic blocks. The programme was further enriched by a special parallel session, the Container Forum, organised by the “Jožef Stefan” Institute.
On the first day of the conference, 19 May, there was also a meeting of representatives of Central European HPC Competence Centres, followed by the panel EuroHPC Ecosystem: How to get access for HPC and AI.
New features of this year’s meeting included two roundtable discussions:
- Achieving Gender Balance in HPC addressed gender balance issues in the HPC research environment on Tuesday,
- AI Factory took place on Wednesday, with a focus on setting up AI factories in Italy, Slovenia and Austria.
The event was organised by the national competence centres for supercomputing, big data and artificial intelligence NCC Austria and NCC SLING Vienna Scientific Cluster (Austria), Research Area Scientific Computing – Universität Innsbruck (Austria), Institute of Science and Technology Austria (Austria), the SLING consortium and the Academic and Research Network of Slovenia.
ASHPC25 reaffirmed its role as a key platform for networking, knowledge sharing and building international collaboration v svetu superračunalništva, odprte znanosti in umetne inteligence. in the world of supercomputing, open science and artificial intelligence. The abstracts of the papers are collected in an e-book, while the full programme remains available on the official conference webstie.
