Tutorial: Reducing Trace File Size for IntelĀ® Trace Analyzer and Collector
Enable
trace collection for a specific number of processes using the PROCESS
option.
To do this:
Create a new configuration file.
To get the trace data for four processes, specify the PROCESS option in the configuration file:
PROCESS 0:N OFF
PROCESS 0:3 ON
Save the configuration file. Specify the name of the file, for example, my_settings_process.conf.
Set the VT_CONFIG environment variable to the directory that contains the configuration file:
VT_CONFIG=/<configuration file path name>/my_settings_process.conf
Run the application.
Linux* OS:
$ mpirun -trace -n 4 ./poisson
Windows* OS:
