NAME¶

TAU_REGISTER_THREAD - Register a thread with the profiling system

SYNOPSIS¶

C/C++:

TAU_REGISTER_THREAD(void);

Fortran:

TAU_REGISTER_THREAD(void);

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
