Change directories to $STUDENT_SRC/components/examples and edit task4_rc. This file will assemble and run an application using the new proxy component you've created.

	Note
	If you installed the cca tools yourself, you will need to modify task4_rc to reflect the location of the performance component.

Run the script with ccafe-single --ccafe-rc task4_rc. It should run without errors and give you a result like Value = 3.140347 as before.

Now look in the $STUDENT_SRC/components/examples directory and you should file a file called profile.0.0.0. This file contains profile data for the last run. View it by executing pprof and you should get output similar to this:

Reading Profile files in profile.*
