Tutorial: Reducing Trace File Size for Intel® Trace Analyzer and Collector
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. |
