Austrian-Slovenian HPC Meeting 2026 – ASHPC26

ASHPC26 will take place at TUtheSky, TU Wien, Vienna, Austria, 8–10 April 2026.

ASHPC26 will continue the tradition of the annual Austrian HPC Meetings (2015–2020) and the Austrian-Slovenian HPC Meetings (2021–2025) bringing together users and providers of large-scale computing resources for both academic and non-academic research and development.

ASHPC26 will focus on various aspects of High-Performance Computing (HPC) and provides a great opportunity to discuss HPC-related topics and present your latest results. It will also provide an overview and update on the rapidly improving AI and HPC landscape available to European researchers and serve as a platform for exchanging experiences related to the usage and operation of large-scale computing resources and the challenges encountered.

ASHPC26 will offer a special technical track:

System Architecture, Configuration, and Operations of HPC and AI-Optimized Supercomputers

This session explores the practical challenges and best practices in the architecture, configuration, and day-to-day operation of modern HPC and AI-optimized supercomputers. Suggested topics are: supporting heterogeneous workloads, secure multitenancy, efficient and fast file transfer, inner workings of storage systems, efficient installation and presentation of user software, architecture and operation of AI-optimized supercomputers, cloud services, and AI factory use cases. Any other relevant topic is welcome.

Central European NCCs Workgroup Meeting – CE-NCCs-WG, 7 April 2026

On Tuesday, 7 April 2026, in the afternoon preceding ASHPC26, there will be a Central European NCCs Workgroup Meeting (for NCC / EuroCC 3 staff only) where the National Competence Centres (NCCs) address their most challenging topics and further regional collaboration.
