Warning!

Puhti and Mahti will be decommissioned after Roihu becomes available. Users should clean up unnecessary files and move any required data by the end of August 2026. See the Roihu data preparation instructions for details.

Puhti scratch is very full: keep only active data there and move or delete everything else. No new Puhti scratch quota will be granted.

I'm moving abroad. Can I still use CSC services?

If you are leaving abroad, e.g., as a visiting or post-doc researcher, you have the right to use CSC's services as long as some connection to a Finnish higher education institution or state research institute remains. This could be, for example, a collaboration with your old research group, in which case you could be invited to a CSC project by the PI as an international collaborator. For more details, see Free-of-charge use cases.

In case you have problems using CSC's services abroad, please contact CSC Service Desk to locate the problem.
