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.

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.
