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.
MUSICA is operated by the Austrian Scientific Computing (ASC) consortium, which consists of Technische Universität Wien, the University of Vienna, University of Natural Resources and Life Sciences, Vienna (BOKU), the Universität Innsbruck, Technische Universität Graz, Johannes Kepler Universität Linz and Institute of Science and Technology Austria.
Three sites: Vienna, Linz, Innsbruck
The system is physically distributed across three sites – in Vienna, Linz and Innsbruck – and operated as one integrated cluster. Through its integration with Austria’s first productively usable quantum computer, OTTER, MUSICA also provides a low‑threshold environment for exploring hybrid HPC-quantum workflows and testing real‑world quantum use cases.
EnergyEfficiency was a key design goal. Most of the system uses direct hot‑water cooling, with cooling elements mounted directly on CPUs, GPUs and memory modules. This allows year‑round free cooling and significantly reduces energy demand compared to air‑cooled systems.
Official funding
MUSICA was funded with EUR 20 million by the FFG Austrian Research Promotion Agency under the Quantum Austria programme and the EU Recovery and Resilience Plan, with a further EUR 16 million provided by the Austrian Bundesministerium für Frauen, Wissenschaft und Forschung (Federal Ministry of Women, Science und Researc, BMBWF). The procurement and #HPC integration of the #quantum computer in the Quantum Accelerated Computing Infrastructure (QACI) project received an additional EUR 9 million (FFG/Quantum Austria/Recovery and Resilience Plan).
Researchers at the partner universities use MUSICA free of charge; companies and public institutions gain access via pay‑per‑use. The first industrial users already have access to MUSICA for their simulations.
