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
