Serial CPU Time

Metric Description

Serial CPU Time is the
CPU
time (compare with Serial Time outside parallel regions ) spent by the application outside any OpenMP region in the master thread during collection. It directly impacts application Collection Time and scaling. High values signal a performance problem to be solved via code parallelization or algorithm tuning.

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.
