VPU Utilization

Metric Description

This metric measures the fraction of micro-ops that performed packed vector operations of any vector length and any mask. VPU utilization metric can be used in conjunction with the compiler's vectorization report to assess VPU utilization and to understand the compiler's judgement about the code. Note that this metric does not account for loads and stores and does not take into consideration vector length as well as masking. Includes integer packed simd.

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.
