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.
