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.

General instructions

  • The LUMI software policy is that users should install required software themselves.
  • To support this process, the EasyBuild tool is provided with accompanying build recipes for several applications. For more details, see the LUMI software documentation pages.
  • Compiling applications manually is of course also possible. Please see the LUMI documentation for more information on developing and compiling applications in the LUMI programming environment.
