CPU Metrics

This section describes all CPU metrics accessible from the Intel® GPA.
Metric Name
Description
Aggregated CPU Load
Represents the percentage of time that all cores of the CPU are being utilized by any application on the device.
Improving Performance
If the
Aggregated CPU Load
metric is high but the
Target App CPU Load
metric is low, check whether another higher priority process on the device is taking time away from your application.
Application Time
Represents the time elapsed from the application start in microseconds.
CPU n Load
Represents the CPU utilization metric of the target system reported per CPU for all processes.
There is one metric per each core on the system: CPU 0 Utilization is the core utilization of CPU 0, CPU 1 Utilization is the core utilization of CPU 1, and so on.
CPU n Frequency
Represents the CPU frequency metric of the target system reported per CPU for all processes.
There is one metric per each core on the system: CPU 0 Frequency is the core frequency of CPU 0, CPU 1 Frequency is the core frequency of CPU 1, and so on.
Target App CPU Load
Represents the aggregated (all cores) CPU utilization of the target application.
 

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.
