Tutorial: Reducing Trace File Size for Intel® Trace Analyzer and Collector
Use
the -trace-collectives
and -trace-pt2pt
options to get information only about the Collective and Point-to-Point
operations in the application.
These options are only supported at runtime with the Hydra Process Manager.
The –trace-collectives and –trace-pt2pt options use the configuration file specially set for these options and redefine the VT_CONFIG environment variable. When you use these options, Intel® Trace Collector will not read your own configuration file.
