Finding Hotspots

You can use the Intel® VTune™ Amplifier to identify and analyze hotspot functions in your serial or parallel application by performing a series of steps in a workflow. This tutorial guides you through these workflow steps while using a sample multithreaded application named nqueens_parallel.

Workflow steps to find hotspots

Step 1: Prepare for analysis

Do one of the following:

Step 2: Find hotspots

Step 3: Analyze parallelism

Step 4: Identify locks

Step 5: Check your work

Re-build the target, re-run the Locks and Waits analysis, and compare the result data before and after optimization.
