Bottom of the Survey Report window
From left to right:
Source tab - View source code for a selected loop.
Top Down tab -
View the function/loop hierarchy in a stack, and the source code associated with a specific function or loop. Each function or loop appears on a separate grid line. Loops are identified with an
icon, the word
[loop, followed by the source location and the function or procedure name that executes it.
Loop Analytics tab - View the most important statistics for a selected loop.
Loop Assembly tab - View assembly representation for a selected loop.
Recommendations tab - Explore code-specific recommendations for how to fix vectorization issues (Vectorization Advisor only).
Why No Vectorization? tab - View the reason automated vectorization failed (Vectorization Advisor only).
The following are available in the advice directory in the Intel Advisor installation directory:
A full list of all recommendations reported by the Vectorization Advisor
A full list of compiler diagnostic data integrated into the Vectorization Advisor interface

There are many controls available to help you focus on the data most important to you, including the following:
1 |
Click the control to save a read-only result snapshot you can view any time. Intel Advisor stores only the most recent analysis result. Visually comparing one or more snapshots to each other or to the most recent analysis result can be an effective way to judge performance improvement progress. To open a snapshot, choose File > Open > Result... |
