Warning!

Puhti and Mahti are being decommissioned in stages, and their storage areas will become fully unavailable from 15 October 2026. Clean up unnecessary files and move any data you need to keep by 31 August 2026. See the Roihu data migration guide for instructions on transferring your data to Roihu.

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.
