NAME
TAU_PROFILE_SET_NODE - Informs the measurement system of the node idSYNOPSIS
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
