Collecting Traces from Applications

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


You need the following to collect traces from an application:
  • An application that uses the TBB library flow graph interface
  • Threading Building Blocks 4.3 or higher
  • 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
. 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; }

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
