Starting an interactive session on Snowy

This page describes how to start an interactive session on Snowy, unlike the general information on starting an interactive session.

To start an interactive session, in a terminal, type:

interactive -A [project name] -M snowy

For example:

interactive -A uppmax2023-2-25 -M snowy

This starts an interactive session using project uppmax2023-2-25 that has a default duration of 1 hours.

Forgot your Snowy project?

One can go to the SUPR NAISS pages to see one's projects,

Example of the Snowy project called 'UPPMAX 2023/2-25'

On the SUPR NAISS pages, projects are called 'UPPMAX [year]/[month]-[day]', for example, 'UPPMAX 2023/2-25'. The UPPMAX project name, as to be used on Snowy, has a slightly different name: the account name to use on Snowy is uppmax[year]-[month]-[day], for example, uppmax2023-2-25

To increase the duration of the interactive session, add the use of -t:

interactive -A [project name] -M snowy -t [session_duration]

For example:

interactive -A uppmax2023-2-25 -M snowy -t 8:00:00

This starts an interactive session using project uppmax2023-2-25 that has a maximum duration of 8 hours.

Has Snowy frozen?

It can take tens of seconds before the computer core(s)/node(s) are allocated.

Snowy has not frozen, just be a bit more patient.
