Description

The TAU_PROFILE_SET_THREAD macro sets the thread 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.<THREAD>.<context>.<thread>. Note that it is not necessary to call TAU_PROFILE_SET_THREAD when you configued with a threading package (including OpenMP).

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_THREAD(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_THREAD(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
    

Python:

import pytau

pytau.setThread(0)
