Use the -trace-collectives and -trace-pt2pt
options to get information only about the Collective and Point-to-Point operations in the
application.
Note
These options are only supported at runtime with the Hydra Process Manager.
Note
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.
