      This runs a 4 degree global ocean climatological simulation.  
      By default this code is set to use two processors splitting  
      the model domain along the equator. Textual output is written  
      to files STDOUT.* and STDERR.* with one file for each process.  
      Model fileds are written to files suffixed .data and .meta  
      These files are written on a per process basis. The .meta  
      file indicates the location and shape of the subdomain in  
      each .data file.  
      This 4 degree global ocean climatological simulation is the baseline  
      configuration for the MITgcmUV code. The change files that  
      convert the model to a different configuration in the  
      verification directory all assume that the model is configured for  
      the baseline case and change the model code accordingly.
