WIP: TUT: tutorial adjustment for backward compatibility

- old logic (v2206 and earlier) always disabled writing on non-master,
  but other parts of the code were more recently updated to use lazy
  evaluation of surface data (with parallel communication)

- now retain full write/no-write logic identically on all ranks. Take
  care of master/non-master at the final output stage.
