TAU_PROFILE_TIMER_DY(3) TAU Instrumentation API TAU_PROFILE_TIMER_DY(3)

NAME

TAU_PROFILE_TIMER_DYNAMIC - Defines a dynamic timer.

SYNOPSIS

C/C++:

TAU_PROFILE_TIMER_DYNAMIC(Profiler timer, char* or string& function_name, char* or string& type, TauGroup_t group);

Fortran:

TAU_PROFILE_TIMER_DYNAMIC(integer profiler(2), character name(size));

DESCRIPTION

TAU_PROFILE_TIMER_DYNAMIC operates similar to TAU_PROFILE_TIMER except that the timer is created each time the statement is invoked. This way, the name of the timer can be different for each execution.

EXAMPLE

C/C++ : 

int main(int argc, char **argv) {
  int i;
  TAU_PROFILE_TIMER(t,"main()", "", TAU_DEFAULT);
  TAU_PROFILE_SET_NODE(0);
  TAU_PROFILE_START(t);
  for (i=0; i&5; i++) {
    char buf[32];
    sprintf(buf, "Iteration %d", i);
    TAU_PROFILE_TIMER_DYNAMIC(timer, buf, "", TAU_USER);
    TAU_PROFILE_START(timer);
    printf("Iteration %d\n", i);
    f1();
    TAU_PROFILE_STOP(timer);
  }
  return 0;
}

Fortran :

subroutine ITERATION(val)
  integer val
  character(13) cvar
  integer profiler(2) / 0, 0 /
  save profiler
  print *, "Iteration ", val
  write (cvar,'(a9,i2)') 'Iteration', val
  call TAU_PROFILE_TIMER_DYNAMIC(profiler, cvar)
  call TAU_PROFILE_START(profiler)
  call F1()
  call TAU_PROFILE_STOP(profiler)
  return
end
