TAU_PROFILE_TIMER_DY(3) 				      TAU Instrumentation API					   TAU_PROFILE_TIMER_DY(3)

NAME

       TAU_PROFILE_TIMER_DYNAMIC - Defines a dynamic timer.

SYNOPSIS

       C/C++:

       TAU_PROFILE_TIMER_DYNAMIC(Profiler timer, char* or string& function_name, char* or string& type, TauGroup_t group);

       Fortran:

       TAU_PROFILE_TIMER_DYNAMIC(integer profiler(2), character name(size));

DESCRIPTION

       TAU_PROFILE_TIMER_DYNAMIC operates similar to TAU_PROFILE_TIMER except that the timer is created each time the statement is invoked. This
       way, the name of the timer can be different for each execution.

EXAMPLE

       C/C++ :

       int main(int argc, char **argv) {
	 int i;
	 TAU_PROFILE_TIMER(t,"main()", "", TAU_DEFAULT);
	 TAU_PROFILE_SET_NODE(0);
	 TAU_PROFILE_START(t);

	 for (i=0; i&5; i++) {
	   char buf[32];
	   sprintf(buf, "Iteration %d", i);

	   TAU_PROFILE_TIMER_DYNAMIC(timer, buf, "", TAU_USER);
	   TAU_PROFILE_START(timer);
	   printf("Iteration %d
", i);
	   f1();

	   TAU_PROFILE_STOP(timer);
	 }
	 return 0;
       }

       Fortran :

       subroutine ITERATION(val)
	 integer val
	 character(13) cvar
	 integer profiler(2) / 0, 0 /
	 save profiler

	 print *, "Iteration ", val

	 write (cvar,'(a9,i2)') 'Iteration', val
	 call TAU_PROFILE_TIMER_DYNAMIC(profiler, cvar)
	 call TAU_PROFILE_START(profiler)

	 call F1()
	 call TAU_PROFILE_STOP(profiler)
	 return
       end

TAU_PROFILE_SET_NODE(3) 				      TAU Instrumentation API					   TAU_PROFILE_SET_NODE(3)

NAME

       TAU_PROFILE_SET_NODE - Informs the measurement system of the node id

SYNOPSIS

       C/C++:

       TAU_PROFILE_SET_NODE(int node);

       Fortran:

       TAU_PROFILE_SET_NODE(integer node);

DESCRIPTION

       The TAU_PROFILE_SET_NODE macro sets the node identifier of the executing task for profiling and tracing. Tasks are identified using node,
       context and thread ids. The profile data files generated will accordingly be named profile.<node>.<context>.<thread>. Note that it is not
       necessary to call TAU_PROFILE_SET_NODE when using the TAU MPI wrapper library.

EXAMPLE

       C/C++ :

       int main (int argc, char **argv) {
	 int ret, i;
	 pthread_attr_t  attr;
	 pthread_t	 tid;
	 TAU_PROFILE_TIMER(tautimer,"main()", "int (int, char **)",
			   TAU_DEFAULT);
	 TAU_PROFILE_START(tautimer);
	 TAU_PROFILE_INIT(argc, argv);
	 TAU_PROFILE_SET_NODE(0);
	 /* ... */
	 TAU_PROFILE_STOP(tautimer);
	 return 0;
       }

       Fortran :

	    PROGRAM SUM_OF_CUBES
	      integer profiler(2) / 0, 0 /
	       save profiler
	     INTEGER :: H, T, U
	       call TAU_PROFILE_INIT()
	       call TAU_PROFILE_TIMER(profiler, 'PROGRAM SUM_OF_CUBES')
	       call TAU_PROFILE_START(profiler)
	       call TAU_PROFILE_SET_NODE(0)
	     ! This program prints all 3-digit numbers that
	     ! equal the sum of the cubes of their digits.
	     DO H = 1, 9
	       DO T = 0, 9
		 DO U = 0, 9
		 IF (100*H + 10*T + U == H**3 + T**3 + U**3) THEN
		    PRINT "(3I1)", H, T, U
		 ENDIF
		 END DO
	       END DO
	     END DO
	     call TAU_PROFILE_STOP(profiler)
	     END PROGRAM SUM_OF_CUBES
