GUI Description
Function
The Source tab page displays the operator instruction heatmap, and allows you to view the mapping between operator source code and instruction sets and the duration. During Ascend C operator development, developers can analyze the performance.
GUI Display
Import the operator instruction hotspot file in BIN format by referring to Importing Data. For details about how to obtain the operator instruction hotspot file in BIN format, see "msprof op simulator" in Operator Tuning (msProf) in Operator Development Tool User Guide. The file is visualize_data.bin.
The Source tab page consists of three parts: filter bar (area 1), source file code attributes (area 2), and instructions (area 3), as shown in Figure 1.
- Area 1: filter bar. You can filter the content to be viewed by Core and Source.
- Area 2: source file code attributes. You can view the code of each line and the execution duration and times. Table 1 describes the fields in the table.
