Metric Description

This metric represents how efficiently the application utilized the CPUs available and helps evaluate the parallel efficiency of the application. It shows the percent of average CPU utilization by all logical CPUs on the system. Average CPU utilization contains only effective time and does not contain spin and overhead. A CPU utilization of 100% means that all of the logical CPUs were loaded by computations of the application.

Possible Issues

The metric value is low, which may signal a poor logical CPU cores utilization caused by load imbalance, threading runtime overhead, contended synchronization, or thread/process underutilization. Explore CPU Utilization sub-metrics to estimate the efficiency of MPI and OpenMP parallelism or run the Threading analysis to identify parallel bottlenecks for other parallel runtimes.
