File Browser

Overview

The file browser provides easy access to your /home, /xdisk, and /groups directories and allows you to view, edit, copy, and rename your files. You may also transfer small files between HPC and your local workstation using this interface. For larger transfers, see our section on Transferring Data for more efficient methods. 

 Access

Access Files

In the browser at the top of the screen, select the Files dropdown

You will be able to select your home directory, /groups, or /xdisk. If you select /groups or /xdisk, enter your PI's NetID in the Filter field to find your shared group space.

 Editing Files

Editing Files

First, navigate to the file you wish to edit. Then, click the vertical ellipses on the right-hand side and select Edit

This will open a file editor in your browser where you may select your color theme, text size, and syntax highlighting.

 Uploading/Downloading Files
The OnDemand file manager is a quick easy way to transfer small files (<1GB). For larger files, see: Transferring Data

Uploading Files

In the file browser, navigate to the directory where you would like to upload your files, then select "Upload" :

This will bring up a popup where you can open a file browser to search for your files. Alternatively, you can drag/drop files/directories onto the tile.

Downloading Files

To download small files from your HPC account to your local workstation, navigate to the file(s) you'd like to to transfer and check the box(es) on the left. Clicking download will initiate the transfer to your local Downloads directory.

 

Job Viewer and Composer

 Job Viewer

Job Viewer

The Job Viewer allows you to check the status and time remaining of your running jobs. You can also cancel your jobs using this interface. Note: be careful looking at All Jobs since this will likely timeout trying to organize them all. To use the Job Viewer, navigate to the Jobs dropdown and select Active Jobs.

This will open a new page listing all your running and pending jobs. You may delete them by clicking the red trash icon under Actions, or view more information about individual jobs using the dropdown on the left next to the ID.

 Job Composer

Job Composer

The Job Composer lets you create and run a SLURM script on any of our three clusters. It should be noted that the Job Composer creates a special string of directories in your /home starting with ondemand/ which is where both your submission scripts and output files will be stored. Make note of the path to your files on the right-hand side of the Job Composer screen under Script location.
