This is used only in the parallel version $ of the model. To keep the input file consistent, it is always needed. $ IOSTYP = 1 is generally recommended. IOSTYP > 2 may be more efficient $ for massively parallel computations. Only IOSTYP = 0 requires a true $ parallel file system like GPFS. $ $ IOSTYP = 0 : No data server processes, direct access output from $ each process (requirese true parallel file system). $ 1 : No data server process. All output for each type $ performed by process that performes computations too. $ 2 : Last process is reserved for all output, and does no $ computing. $ 3 : Multiple dedicated output processes. $ 0 $ $ Five output types are available (see below). All output types share $ a similar format for the first input line: $ - first time in yyyymmdd hhmmss format, output interval (s), and $ last time in yyyymmdd hhmmss format (all integers). $ Output is disabled by setting the output interval to 0. $ $ Type 1 : Fields of mean wave parameters $ Standard line and line with flags to activate output fields $ as defined in section 2.4 of the manual.
