Job Metrics with XDMod

Reviewing data about how your jobs perform can help you make better use of resources. On Palmetto, we provide access to metrics we collect via the XDMoD web interface.

Limited to Clemson Network

XDMoD can only be accessed over the Clemson Network. If you are off-campus, connect to Clemson University VPN first.

What is XDMoD

XDMoD, short for XD Metrics on Demand, is a tool that allows users of HPC clusters to see their job history and metrics about performance. We use Open XDMoD on Palmetto, which is an open-source version funded by the National Science Foundation.

What Information Can I See in XDMoD?

The following metrics are collected for each job:

• Number of Jobs Submitted
• Number of Jobs Started
• Number of Jobs Running
• Number of Jobs Ended
• Queue Time
• Wall Time
• CPU Time
• GPU Time
• Job Size

How Can I Analyze My Metrics?

Arguably the most useful feature of XDMoD is the Usage Explorer, which will allow you to see how your metrics change over time.
