Collecting Traces from Applications

This section explains how to collect traces from an application that uses the
Intel® oneAPI Threading Building Blocks
 (
oneTBB
) flow graph interfaces.

Prerequisites

You need the following to collect traces from an application:
  • An application that uses the
    oneTBB
     library flow graph interface
  • The Flow Graph Collector library
Check the links in the Additional Resources section if you are missing any of these prerequisites.

Simple Sample Application

This section uses the sample code below as a running example. Assume this code is contained in a file
example.cpp
. You can also use your own application or sample instead of this simple example. 

#include "tbb/flow_graph.h"
#include <iostream>
using namespace std;
using namespace tbb::flow;
int main() {
  graph g;
  continue_node< continue_msg> hello( g, 
    []( const continue_msg &) {
      cout << "Hello";
    }
  );
  continue_node< continue_msg> world( g, 
    []( const continue_msg &) {
      cout << " World\n";
    }
  );
  make_edge(hello, world);
  hello.try_put(continue_msg());
  g.wait_for_all();
  return 0;
}
