Tutorial: Analyzing MPI Applications with Intel® Trace Analyzer and Collector and Intel® VTune™ Amplifier XE
Use
the Intel® VTune™ Amplifier to analyze an MPI application behavior to
improve the application performance on the intra-process level.
This part of the tutorial uses the poisson sample code to demonstrate how to detect and remove hotspots in your application.
Run the Basic Hotspots analysis to identify the functions that took a relatively long time to execute. |
|
Explore the application-level performance, analyze the most time-consuming functions, and identify the hotspot code region. |
