Tutorial: Analyzing MPI Applications with Intel® Trace Analyzer and Collector and Intel® VTune™ Amplifier XE
Use
the Intel® Trace Analyzer to analyze an MPI application's behavior to
improve performance at the inter-process level.
This part of the tutorial uses the sample trace files poisson_sendrecv.single.stf and poisson_icomm.single.stf to demonstrate how to detect and remove serialization in your application.
Step 1: Prepare for analysis |
|
Step 2: Detect serialization |
|
Step 3: Remove serialization |
Improve your application performance by replacing the problem-causing function. |
Step 4: Check the result |
|
Step 5: Analyze optimized communications |
