CPU Metrics

本节描述了可从 Intel® GPA 访问的所有 CPU 指标。
指标名称
描述
Aggregated CPU Load
代表设备上任何应用程序正在使用的 CPU 所有内核的时间百分比。
改善性能
Aggregated CPU Load
指标高,但
Target App CPU Load
指标低时,检查设备上是否有另一个更高优先级的进程正从您的应用程序争夺时间。
Application Time
代表自应用程序启动后经过的时间,以微秒表示。
CPU n Load
代表每个 CPU 针对所有进程报告的目标系统的 CPU 利用率指标。
系统的每个内核均有一个指标:CPU 0 Utilization 是 CPU 0 的内核利用率,CPU 1 Utilization 是 CPU 1 的内核利用率,依此类推。
CPU n Frequency
代表每个 CPU 针对所有进程报告的目标系统的 CPU 频率指标。
系统的每个内核均有一个指标:CPU 0 Frequency 是 CPU 0 的内核频率,CPU 1 Frequency 是 CPU 1 的核心频率,依此类推。
Target App CPU Load
代表目标应用程序的合计(所有内核)CPU 利用率。
 

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.
