Effective CPU Utilization

Metric Description

How many of the logical CPU cores are used by your application? This metric helps evaluate the parallel efficiency of your application. It estimates the percentage of all the logical CPU cores in the system that is spent in your application -- without including the overhead introduced by the parallel runtime system. 100% utilization means that your application keeps all the logical CPU cores busy for the entire time that it runs.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
