Memory Access Patterns Analysis Purpose and Usage
View information about types of memory access inside selected loops/functions.
Memory Access Patterns Analysis Prerequisites
To prepare to run a Memory Access Patterns analysis:
Do one of the following to open the Analysis Target tab in the Project Properties dialog box:
In the Intel Advisor GUI, choose Project > Project Properties…
In the Visual Studio IDE, choose Project > Intel Advisor [version] Project Properties....
Choose the Memory Access Patterns Analysis type, then specify the same application as in the Survey Hotspots Analysis type, but a smaller input data set if possible.
Generate a Survey Report.
Mark one or more loops for deeper analysis by enabling the corresponding
checkboxes in the
Survey Report.
Tip
If possible, use the Inherit settings from Survey Hotspots Analysis Type checkbox.
The Memory Access Patterns Analysis type consumes more resources than the Survey Hotspots Analysis type. If analysis takes too long, consider decreasing the workload.
Setting search directories in the Binary/Symbol Search tab and Source Search tabs is optional for the Vectorization Advisor.
Marking loops for deeper analysis using the
checkbox is a
Vectorization Advisor-specific alternative to adding annotations in target application source code.
Memory Access Patterns analysis is time intensive. The fewer loops you mark for deeper analysis, the less time it takes to collect the data.
Choose the optimal compiler settings. The most up-to-date settings are in User Guide: Before You Begin.
Run a Memory Access Patterns Analysis
To run a Memory Access Patterns Report, do one of the following:
Click the
button under
Check Memory Access Patterns in the
Workflow tab.
In the Visual Studio Solution Explorer, right-click the project, then choose Intel Advisor [version] > Start Memory Access Patterns Analysis.
While analysis is running, you can do the following under the appropriate analysis step in the Workflow tab
Stop analysis and data collection, and retain the already collected data: Click the
button.
Cancel analysis and data collection, and discard the collected data: Click the
button.
Interrupt post-collection data finalization: Click the
button.
