/** \mainpage ROC Profiler Binary Test
 *
 * \section introduction Introduction
 *
 * The goal of this test is to test ROC profiler as a binary against a
 * multithreaded application.Test application launches an empty kernel
 * on multiple threads.
 *
 * The test then parses the csv and verifies if the nuber of kernel dispatches
 *  are equal to number of threads launched in test application.
 *
 * Test also does some basic verification if counter values are non-negative
