NAME¶

TAU_REGISTER_THREAD - Register a thread with the profiling system

SYNOPSIS¶

C/C++: Fortran:

DESCRIPTION¶

To register a thread with the profiling system, invoke the TAU_REGISTER_THREAD macro in the run method of the thread prior to executing any other TAU macro. This sets up thread identifiers that are later used by the instrumentation system.

EXAMPLE¶

C/C++ :

void * threaded_func(void *data) {
  TAU_REGISTER_THREAD();
  { /**** NOTE WE START ANOTHER BLOCK IN THREAD */
    TAU_PROFILE_TIMER(tautimer, "threaded_func()", "int ()", 
                      TAU_DEFAULT);
    TAU_PROFILE_START(tautimer);
    work(); /* work done by this thread */
    TAU_PROFILE_STOP(tautimer);
  }
  return NULL;
}
    

Fortran :

call TAU_REGISTER_THREAD()
    

CAVEAT¶

PDT based tau_instrumentor does not insert TAU_REGISTER_THREAD calls, they must be inserted manually
