Tutorial: Reducing Trace File Size for Intel® Trace Analyzer and Collector
This section describes the steps you need to do before you start using the Intel® Trace Analyzer and Collector.
To perform all the steps described in this tutorial, you will need the following software installed on your system:
All of these products are installed as part of Intel® Parallel Studio XE Cluster Edition.
Linux* OS:
Set the required environment variables by sourcing the psxevars.c[sh] script available at <install-dir>/parallel_studio_xe_<version>.x.xxx/bin, where <install-dir> is the Intel® Parallel Studio XE Cluster Edition installation directory. For example:
$ source psxevars.sh
Windows* OS:
Open the command prompt from Start > Intel Parallel Studio XE version > Compiler and Performance Libraries > Intel 64 Visual Studio version environment. This will set all required environment variables and you will be ready to trace your applications.
To trace the poisson application, go to <install-dir>/examples/poisson and copy its contents into your working directory, then trace the application:
Linux* OS:
Compile the application running the make command. Adjust the Makefile, if necessary.
Run the application with the -trace option of mpirun:
$ mpirun -n 4 -trace ./poisson
Windows* OS:
Compile all components of the poisson application from the compiler command prompt with the -trace option. The basic command line for Fortran programs is:
> mpiifort -trace myApp.f90
Run the application to generate a tracefile:
> mpiexec -n 4 myApp.exe
For your convenience, this tutorial comes with a set of trace files available at <install-dir>/examples/traces.
Once you have the trace data available for the poisson application, you are ready to start the analysis.
