Microarchitecture Usage

Metric Description

Microarchitecture Usage metric is a key indicator that helps estimate (in %) how effectively your code runs on the current microarchitecture. Microarchitecture Usage can be impacted by long-latency memory, floating-point, or SIMD operations; non-retired instructions due to branch mispredictions; instruction starvation in the front-end.

Possible Issues

You code efficiency on this platform is too low.
Possible cause: memory stalls, instruction starvation, branch misprediction or long latency instructions.


Run Microarchitecture Exploration analysis to identify the cause of the low microarchitecture usage efficiency.
