The command jobhtop <jobID> gives more details about your job. Specifically, it shows the resource usage of your job so you can determine if your job needs more/less resources and can make the necessary changes.

Once in the jobhtop screen, pressing F2 will allow you to customize which columns and information you want displayed about your job.

• Press F2 for Setup
• Under the green Setup column, use the down key to go to Columns, press Enter
• There, use the arrow keys to move over to Available Columns, and press F5 (Add) to add which information you want displayed on the main jobhtop page
• Press F10 once you’re done customizing

Meaning of Columns:

• MEM% - Shows how much memory a job is using out of available physical memory
• CPU% - Percentage of the CPU time the process is currently using; 100% means it is using the full capacity of the core
• I/O Rate - Shows the rate of data transfer in bytes per second
