Run Microarchitecture Exploration Analysis

After running the Hotspots analysis on the
matrix
sample, microarchitecture usage inefficiency was highlighted as the top issue in the
Insights
pane.
Once you have determined hotspots in your code, perform Microarchitecture Exploration analysis to understand how efficiently your code is passing through the core pipeline. During Microarchitecture Exploration analysis,
Intel® VTune™
Profiler
collects a selected list of hardware events for analyzing a typical user application. It calculates a set of predefined hardware metrics and facilitates identifying hardware-level performance problems.
  1. Click
    Configure Analysis
    to begin a new analysis.
  2. In the
    HOW
    pane, click the Browse button and select the
    Microarchitecture Exploration
    analysis type.

  3. Click the
    Start
    button to run the analysis.
VTune
Profiler
launches the
matrix
application, runs the analysis, and finalizes the collected results. The results are shown in the
Microarchitecture Exploration
viewpoint.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
