Attention

WARNING: From 9am on 19th August until 5pm on 2nd September there will be no access to the Stanage HPC cluster.

We will send an email to notify you when Stanage is back online and available for job submission.

Attention

The ShARC HPC cluster was decommissioned on the 30th of November 2023 at 17:00. It is no longer possible for users to access that cluster.

3. Jupyter’s web terminal

You can start a terminal

• Via the top menu bar (File, New, Terminal) or

• Via the Files Launcher tab.

You can use this terminal to perform any command-line-only operation on the cluster, including:

• Managing versions of Notebooks / other code using version control software such as git (as illustrated above);

• Searching for files/directories;

• Configuring Python or R environments (although there is an (enabled) plug-in for creating/selecting environments and installing/upgrading/removing packages using Jupyter’s graphical interface);

• Triggering the automounting of directories not visible in JupyterHub’s file browser.

Having a terminal interface available within the browser negates the need to separately log into the cluster via SSH to access the command-line.

Limitations:

• Not all keyboard shortcuts that typically work in terminal programs work within this web console:

  • tab can be used for tab completion

  • but Ctrl-C kills the program running in the terminal

  • To copy text, select it, right-click and click Copy.

  • To paste text, right-click and click Paste.

• You cannot start graphical programs (e.g. xeyes) from this terminal.
