The Survey tool
runs your serial program's executable and profiles it to identify performance improvement opportunities. After it performs extensive analysis of your program's execution, it displays the
Survey Report to help you decide the possible places to add parallelism. If you recently used a different profiling tool to measure your program's hotspots and understand the code's performance characteristics, consider this step optional.
Before you run the Survey tool, you need to do the following:
-
Decide which part of your program to examine for possible places to add parallelism.
-
Choose the input data set or run-time parameters for your program. If you want to speed up your program generally, you can use typical input data. However, if you want to improve its performance on specific operations that it does particularly slowly, choose input data to emphasize these slow operations. Once you have prepared appropriate input data, configure your program with the chosen data.
- For the selected project, build a target using a Release build. The target must include debug information.
To run the Survey tool with your program, do one of the following:
-
The
button starts executing your target with data collection disabled. Data collection can be enabled either by a Resume Collection annotation or by clicking the
button (see the help topic
While Running the Survey Tool).
-
Click the
or the
button under
1. Survey Target in the
Advisor Workflow tab.
-
Click the
icon in the
Intel Advisor toolbar or the
Tools >
Intel Advisor XE 2016 menu.
