Incoming Bandwidth Bound

Metric Description

This metric represents a percentage of elapsed time the system spent with a high incoming bandwidth utilization of the Intel Omni-Path Fabric. Note that the metric is calculated towards theoretical maximum networking bandwidth and does not take into account dynamic network conditions such as link oversubscription that can reduce the theoretical maximum.

Possible Issues

High incoming network bandwidth utilization was detected. This may lead to increased communication time. You may use Intel Trace Analyzer and Collector for communication pattern analysis.
