Puhti and Mahti computing services have been decommissioned. Puhti and Mahti login nodes and storage services will remain available until 15 October 2026, but are no longer covered by service contracts. Please clean up and migrate your data to Roihu ASAP. See Roihu data migration guide for instructions.

Shell

The shell apps can be found under Pinned Apps or on the top navbar under the Tools section. There are two different shells.

The Login node shell launches a normal Linux shell on one of the login nodes. Any command that is running when the login node shell browser tab is closed will stop. Note that the same rules apply here as during a normal SSH session:

Error-label

Login nodes are only for light pre/postprocessing (see usage policy).

The Compute node shell launches a persistent shell on a compute node for heavier commands that should not be run on login nodes. The persistent shell will keep running even if you close your browser or lose internet connection.
