High performance computing
Modern supercomputers are a necessary research instrument for computing and data-intensive research and companies’ RDI activities. The use of supercomputers, or high-performance computing, is becoming more widespread in all fields of science, and access to efficient computing resources gives a significant boost to research and innovations.
LUMI supercomputer
The European supercomputer LUMI, one of the fastest and greenest of its kind in the world, boosts research, employment, and competitiveness in Finland and across Europe. Throughout its life cycle, LUMI will be one of the most high-profile scientific instruments in the world. LUMI is located in the CSC’s data center in Kajaani.
Supercomputers Mahti and Puhti
CSC’s supercomputers Mahti and Puhti will be phased out during summer 2026 as CSC’s next-generation supercomputer Roihu replaces them. CSC will donate Puhti and Mahti to Finnish universities, universities of applied sciences, and research institutes for research and education.
LUMI AI Factory
Developing AI skills is crucial for Europe’s economic growth, societal well-being, and technological sovereignty. The LUMI AI Factory provides companies and AI researchers with world-class computing power, high-value datasets and related expertise they need in one place.
Roihu supercomputer
Finland’s new national supercomputer Roihu was opened for researchers in June 2026. Roihu will replace CSC’s supercomputers Mahti and Puhti. The national computing environment will provide Finnish researchers with competitive resources.
High-performance computing for companies
Finnish companies can tap into the outstanding computing power of the LUMI supercomputer for their product development and innovation. In addition to computing resources, we provide companies with expert support for deployment, training, and assistance with submitting funding applications, free of charge.
