“show owner/mode”: Show who owns the file/directory (often helpful in shared Project folders).

“show DotFiles”: Show hidden files.

  • Create a new directory

  • Create a new file

  • Download/Upload files to the current directory

  • Copy and Move files to a new location

  • Rename Files

  • Delete Files

  • Edit Files

Note: The current max file size is limit is set to 10GB.

Jobs Dropdown

From the Jobs drop down, you can either view your jobs or all jobs currently running on the Beartooth Cluster. From the Job Composer subpage, you can manage all aspects of running jobs on the Beartooth Cluster:

...

  • Custom prompts may not show up in the shell windows. To get the prompts you can remove the PS1 setting from your .bashrc or manually reset the PS1 variable in the shell window.

  • On the desktop launch windows the Compression and Image Quality sliders fail to show the current setting in the slider as detailed at https://github.com/OSC/ondemand/issues/1384

  • While using the XFCE Interactive Desk, clicking on Home / File System desktop icons.

    • Resolve: Remove the .gvfs folder in your home folder.

Current User Load

SouthPass is a special partition on the cluster, currently with up to two nodes available, and a total of (2 x 28 =) 56 cpus.

...

Whenever a user starts an interactive GUI Desktop they are actually requesting a Slurm job across this partition. We do currently have some limit on the maximum number of users, and this will depend on what configuration users request i.e. 1/2 or 4 cpus and how they can be allocated across the nodes.

  • The number of current users will depend on the number of cores each individual user requests, but we have tested the service with 38 concurrent desktops running different combinations of cores.
