Intel® VTune™ Amplifier
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.
The metric value is low that can indicate poor logical CPU cores utilization because of load imbalance, threading runtime overhead, contended synchronization or thread/process underutilization. Use VTune Amplifier XE Advanced Hotspots analysis to explore opportunities on increasing CPU utilization.
