FPU Utilization

Metric Description

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.

Possible Issues

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.

Product and Performance Information

1

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.
