The first delivery of Finland’s new national supercomputer, Roihu, has arrived at CSC’s data centre in Kajaani, marking the start of installation work.
Roihu is designed to replace the current supercomputers Mahti and Puhti, both of which will be decommissioned in 2026. Once operational, it will triple Finland’s computing capacity compared to today.
The system will serve a wide range of disciplines, from artificial intelligence to large-scale simulations.
It will also support sensitive data analysis, such as medical and ecological information, with strict security controls.
Roihu is expected to play a role in higher education as well, providing a training platform for students across fields and industries.
The installation phase is scheduled to continue until early December, after which CSC will run acceptance tests. A pilot stage for researchers is planned for February 2026, with full access beginning in March.
Puhti’s computing services will close one month after Roihu’s launch, while its storage and login services will remain available until June 2026. Mahti will be retired in August 2026, following about six years of use.
Sebastian von Alfthan, development manager at CSC, said the company is preparing to handle the end-of-life cycle for both systems.
“We will donate the machines for reuse or as spare parts where possible, in line with the interests of science and sustainable development,” von Alfthan said.
Roihu will be housed in the expanded LUMI data centre in Kajaani. The facility has undergone a year-long project to boost electricity and cooling capacity to accommodate the new machine.
Juha Torvinen, project manager for the data centre, said the work has progressed ahead of schedule.
“The expansion has gone well, and the installation of Roihu’s hardware has even started slightly earlier than planned,” Torvinen said.
Roihu is expected to secure Finland’s position as a strong provider of research computing capacity in Europe, complementing the neighbouring LUMI supercomputer, one of the world’s most powerful.
