Analysis Summary

The Analysis Summary page consists of two parts: Analysis Summary and Collection And Platform Info.

On the Analysis Summary page, you need to refer to Merge Reports to import the parent directory of PROF_XXX to display the collected communication duration proportion data of all NPU nodes in the cluster scenario, as shown in Figure 1.
On the Collection And Platform Info page, you can select ID of the target device to view its detailed hardware and profiling information, as shown in Figure 2.

**Table 1** Analysis summary
Field	Description
Analysis Summary	Analysis summary.
Bottlenecks And Profiling Suggestion	Bottlenecks and profiling suggestions.
The communication time ratio of all NPU cards exceeds the threshold of 10%.	The communication duration proportion of every NPU node is greater than 10%.
The communication time ratio of all NPU cards is good and below the threshold of 10%.	The communication duration proportion of every NPU node is lower than 10%.
The communication time ratio of some NPU cards exceeds the threshold of 10%. You need to check whether there are slow nodes or slow links.	The communication duration proportions of some NPU nodes are greater than 10%. Check whether slow nodes or links exist.
Click the Cluster Iteration Analysis tab to obtain more information.	Click Cluster Iteration Analysis for more information.
Top	Top N NPU nodes with the largest communication duration proportions.
Apply	Data export button. If you select a top N value and click this button, the bar chart of top N NPU nodes with the largest communication duration proportions is exported.
Ratio Of The NPU Card	Chart of communication duration proportions of NPU nodes.

Profiling Elapsed Time	Duration of information collection.

**Table 4** Host CPU information
Field	Description
CPU ID	CPU ID.
Name	CPU name.
Type	CPU model.
Frequency	CPU frequency. This parameter is not displayed in some systems because these systems do not have calling frequency APIs. The value of this parameter is subject to the actual situation.
Logical CPU Count	Number of logical CPUs.

Field	Description
AI Core Number	Number of AI Cores.
AI CPU Number	Number of AI CPUs.
Control CPU Number	Number of Ctrl CPUs.
Control CPU Type	Ctrl CPU type.
Device Id	ID of the device associated with the current page.
TS CPU Number	Number of TS CPUs.

The AI Core utilization is displayed in a line chart (displayed only when the sample-based mode is selected).
