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
