Tutorial: Reducing Trace File Size for IntelĀ® Trace Analyzer and Collector
Specify
the STATE option in the configuration file to define the function that
matches the pattern.
To do this:
Create a new configuration file.
In the configuration file, specify STATE to collect the trace data for the MPI_Allreduce and MPI_Sendrecv functions:
STATE MPI:* OFF
STATE MPI:*Allreduce* ON
STATE MPI:*Sendrecv* ON
Save the configuration file: my_settings_state.conf.
Set the VT_CONFIG environment variable to the directory that contains the configuration file:
VT_CONFIG=/<configuration file path name>/my_settings_state.conf
Run the application.
Linux* OS:
$ mpirun -trace -n 4 ./poisson
