Reducing Trace File Size

 Use Intel® Trace Collector for MPI applications to generate trace files of reduced size that you can later analyze in the Intel® Trace Analyzer tool and finally improve the application performance.

This tutorial demonstrates how to reduce the size of the trace file you are going to collect on the example of the poisson sample code.

Option 1: Create Configuration File

Define the trace data filters in the Intel® Trace Collector configuration file.

Option 2: Use Runtime Options

Set the Intel® Trace Collector to collect data on Collective or Point-to-Point operations.

Option 3: Instrument Your Code

Include the MPI_Pcontrol function call into the source code to generate a trace file for a particular segment.
