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

Python:

    import pytau
    pytau.setNode(0)
