インテル® VTune™ Amplifier 2018 ヘルプ
This metric represents how intensively your program uses the FPU. 100% means that the FPU is fully loaded and is retiring a vector instruction with full capacity every cycle of the application execution.
The metric value is low. This can indicate poor FPU utilization because of non-vectorized floating point operations, or inefficient vectorization due to legacy vector instruction set or memory access pattern issues. Consider using vector analysis in Intel Advisor for data and tips to improve vectorization efficiency in your application.
