Resources

Introduction

This module displays resource consumption.

Key metrics

• Number of cores, nodes and GPUs allocated

• Requested and consumed memory

This example shows that most of the jobs consumed less than 10% of the memory they required.

• Requested and consumed memory vs. allocated cores

How it works

Use the date and advanced filters to scope the data to a specific period, partition, or user group before reading the graphs.

The requested vs. consumed memory scatter plot is particularly useful for spotting over-provisioning: a cluster of points near the bottom of the chart (low consumed / high requested ratio) indicates that jobs are requesting significantly more memory than they actually use. The caption “most jobs consumed less than 10% of the memory they required” in the example above is a typical sign of over-provisioning that can be addressed through user guidance or job policies.
