Creating a NUMA Refined Analysis Task

Function

The tool obtains the refined DDR access, NUMA access traffic matrix, and processes' memory access information based on Arm SPE capabilities.

Prerequisites

• No nodes are in the Offline state.
• The OS supports the SPE and PMU, and the SPE environment has been configured. For details, see Configuring the SPE Environment.
• NUMA refined analysis is not supported in the VM environment.

Procedure

1. Click next to System Profiler.

   Choose General Analysis from the drop-down list. The page for creating a task is displayed.

2. Set task parameters by referring to "Task Management" and Table 1.
   Create a NUMA refined analysis task. See Figure 1.

   Table 1 Parameters for creating a NUMA refined analysis task

   Parameter	Description
   Task Name	Name of the task. The name must meet the following requirements: Contain only letters, digits, and underscores (_). Contain 1 to 64 characters.
   Select Nodes	Select the nodes to be analyzed. If there is only one node, this node is selected by default. A maximum of 10 nodes can be selected at a time.
   Analysis Object	Select System.
   Analysis Type	Select Memory Access.
   Access Analysis Type	Select NUMA Refined Analysis.
   Sampling Duration (s)	Sampling duration, which must be greater than or equal to Report Interval. The default value is 30. The value ranges 2 to 28800.
   Report Interval (s)	Report interval, in seconds. The default value is 10. The value range is 2 to 30. This parameter needs to be set in Advanced Configurations.
   Sampling Interval (Instructions)	Sampling interval. The default value is 163840. The value range is 1 to 232 – 1. NOTE: To monitor the environment for a long time, you are advised to change the sampling interval to 819200.

3. Click OK.

   You can click the icons next to the task name to perform the following operations:

   • : cancels the analysis task. After an analysis task is canceled, the collected information will be deleted.
   • : restarts the analysis task. You can modify task parameter settings and restart an analysis task. This button is available when a task is canceled or fails.
   • : deletes the analysis task. After a task is deleted, all data of this task will be deleted. Exercise caution when performing this operation.
   • : performs the analysis again. The analysis task is renamed and restarted.
   • : changes the task or report name. The report naming rule is the same as that of a task.
