Intel® VTune™ Amplifier XE and Intel® VTune™ Amplifier for Systems Help
This metric represents how intensively your program uses the FPU. 100% means that FPU is fully loaded.
The metric value is low. This can indicate poor FPU utilization because of non-vectorized floating point operations, or inefficient vectorization because of 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.
