It also maps the current floating point precision (kind=cfp) to the corresponding MPI numeric type. This routine also sets the unit for standard output that each rank will use (the value of stdout). In case of serial run the value stdout is not set here and is left to the default value input_unit as specified in the module const. More...

So, while mpi_running can be used to determine whether the program is running under MPI, the variable mpi_started indicates whether the call to MPI_MOD_START had been already done (even in serial build).
