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.

What does it cost to use Pouta?

Pouta usage is free for Finnish academic use if a project application is accepted. This uses the same process as the HPC systems at CSC. For a detailed explanation, see Pouta Usage policy.

Academic and commercial pricing is also available for cases where we are unable to provide free access or sufficient resources.

Accounting and billing is based on Cloud Billing Units. Academic users can apply for more free Billing Units through the CSC customer portal MyCSC. Paying customers should contact CSC Service Desk.
