Viewing Analysis Results

Prerequisites

A microarchitecture analysis task has been created and the analysis is complete.

Procedure

1. In the System Profiler area on the left, click the name of the target analysis task.

   The node list is displayed.

2. Click the name of the target node to view the analysis results.
   • Click the node name. The Summary tab page is displayed by default, as shown in Figure 1. For details about the parameters, see Table 1.
     

     • The Summary tab page provides metric data based on the top-down model. You can hover the mouse pointer over a metric to view the metric description, exception description, possible causes, and solutions.
     • Click in the upper left corner to switch the view.
     • If an event occupies a large proportion, the specific percentage is displayed next to the event name. You can move the mouse pointer to view the percentage of other events.

     Table 1 Parameters on the Summary tab page

     Parameter	Description
     Clock Cycles	Number of clock cycles in the sampling process.
     Instructions	Number of instructions in the collection process.
     IPC	Number of instructions executed in a single clock cycle (IPC = Number of instructions/Clock cycles).
     Event Percentage	Ratio of the current event to the total events.

   • Click Time Sequence Information to view the time sequence diagram of microarchitecture metrics, as shown in Figure 3.
     

     • The Time Sequence Information tab page displays metric information by time. You can specify different metrics based on time to identify features in different time segments. The displayed data varies according to the collection mode you specify during task creation.
     • You can hover the mouse pointer over a color stripe to view details and click the color stripe to view the lower-level metrics.
     • By default, the first 10 data records are selected and displayed. You can use the mouse wheel or scroll bar on the right to load more data records. If all data records are selected, 10 data records are displayed at each batch.

   • Click the Task Information tab to view the detailed configuration and sampling information about the task on the current node.
     

     If the task fails to be executed, the failure cause is displayed on the Task Information tab page.

     If some data fails to be collected but the overall task execution is not affected, you can view the exception message in Exception Information.

     Collection End Cause displays the reason why the data collection of the current task ends, for example, "Task collection times up."
