  TAU_PHASE_CREATE_STATIC(t2,"IO Phase", "", TAU_USER);
  TAU_PHASE_START(t2);
  input();
  output();
  TAU_PHASE_STOP(t2);
  return 0;
}

Fortran :

subroutine F2()
  integer phase(2) / 0, 0 /
  save    phase
  call TAU_PHASE_CREATE_STATIC(phase,'IO Phase')
  call TAU_PHASE_START(phase)
  call INPUT()
  call OUTPUT()
  call TAU_PHASE_STOP(phase)
end
