Understanding How General Exploration Works in Intel® VTune™ Amplifier XE

The General Exploration Analysis Type in Intel® VTune™ Amplifier XE is used to detect microarchitectural hardware bottlenecks in an application or system. General Exploration uses hardware event counters to detect and locate issues and presents the data in a user-friendly and actionable format. This article will explain the mechanisms used in this analysis, a few best-known-methods for interpreting the results, and the various complexities and issues that arise when doing this type of analysis.

  • Self Time and Total Time

    Intel® VTune™ Amplifier can calculate analysis-independent time spent within particular procedures and functions and within children (callees). This is the information for Self and Total time, respectively. The Bottom-up window shows only Self time. The Top-down Tree window and Source/Assembly window show Self time and Total time.

    Search Order

    When locating binary/symbol/source files, the Intel® VTune™ Amplifier searches the following directories, in the following order:

    1. Directory <result dir>\all (recursively).
