Improving Intra-process Performance


 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.
