TAU_PROFILE_SET_CONT(3) 				      TAU Instrumentation API					   TAU_PROFILE_SET_CONT(3)

NAME
       TAU_PROFILE_SET_CONTEXT - Informs the measurement system of the context id

SYNOPSIS
       C/C++:

       TAU_PROFILE_SET_CONTEXT(int context);

       Fortran:

       TAU_PROFILE_SET_CONTEXT(integer context);

DESCRIPTION
       The TAU_PROFILE_SET_CONTEXT macro sets the context identifier of the executing task for profiling and tracing. Tasks are identified using
       context, context and thread ids. The profile data files generated will accordingly be named profile.<context>.<context>.<thread>. Note that
       it is not necessary to call TAU_PROFILE_SET_CONTEXT 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_SET_CONTEXT(1);
	 /* ... */
	 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)
	       call TAU_PROFILE_SET_CONTEXT(1)
	     ! 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
