Starting an interactive node on Rackham

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

To use an interactive node, in a terminal, type:

interactive -A [project name]

For example:

interactive -A uppmax2023-2-25

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

Forgot your Rackham project?

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

An example of the Rackham 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 Rackham, has a slightly different name: the account name to use on Rackham 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] -t [session_duration]

For example:

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

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

Has Rackham frozen?

It can take tens of seconds before an interactive node is allocated.

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

To stop the session, do:

exit

This will take you back to the login node.
