NAME

       ncmpidiff - compares two netCDF files in parallel

SYNOPSIS

       mpiexec -n np ncmpidiff [-b] [-q] [-h] [-v var1,...]  file1 file2

DESCRIPTION

       ncmpidiff runs in parallel using np number of MPI processes to compare the contents of the
       two files and reports the difference to the standard output.

       If neither argument -v nor -h is given besides the two file names, the  entire  files  are
       compared.

OPTIONS

       -b     Verbose  mode - print results (same or different) for all components (file, header,
              or variables) in comparison

       -q     Quiet mode - print nothing on the command-line output. This also  disables  verbose
              mode.  When  in  quiet  mode,  users  should  check exit status. See below in "EXIT
              STATUS".

       -h     Compare file header only

       -v var1,...,varn
              Compare only the given list of variables

EXIT STATUS

       An exit status of 0 means no differences were found, and 1  means  some  differences  were
       found.  Note on VMS-based system, the exit status values are reversed.
