Job Performance Monitoring
We have recently deployed a new tool for measuring and monitoring job performance called jobstats.
Available on all clusters, jobstats provides a report of the utilization of CPU, Memory, and GPU resources for in-progress and recently completed jobs.
To generate the report simply run (replacing the ID number of the job in question):
[ab123@grace ~]$ jobstats 123456789

* Have a nice day!
When viewed from our User portal graphical interface, these statistics are enhanced with plots of performance over time.
This is a great way to monitor your job's behavior and resource utilization over time.
