! --- this set of routines facilitates output comparison from two HYCOM
! --- versions running side by side. one model, the 'slave', writes its
! --- output into a named pipe. the other model, the 'master', reads
! --- from the pipe and compares.
! --- differences are recorded in 'PIPE_base.out'.
!
! --- call 'pipe_fatal_on' to exit on differences (this is the default)
! --- call 'pipe_fatal_off' to continue on differences
!
! --- call 'pipe_init' at start of main program.
!
! --- if the file 'PIPE_MASTER' exists then this is the master,
! --- if the file 'PIPE_SLAVE' exists then this is the slave,
! --- if the file 'PIPE_SYM' exists then this is master and slave,
! --- if the file 'PIPE_NAN' exists then this is master and slave,
! --- if the file 'PIPE_TRACER' exists then this is master and slave,
! --- otherwise there is no comparison made.
!
! --- if the file 'PIPE_SHIFT' exists for the slave, then it
! --- is a single-line plain text file containing two integers
! --- specifiying how much to periodically shift the slave arrays
! --- before sending them to the master. it is an error for
! --- 'PIPE_SHIFT' to exist (a) on the master and (b) when not
! --- making a comparison.
!
! --- if the file 'PIPE_SYM' exists, there is no slave and the
! --- master compares its own fields for various symmetries.
! --- it is a single-line plain text file containing an integer
! --- specifiying what kind of symmetries to test for (0=constant,
! --- 1=transpose, 2=constant-in-j, -2=arctic, 4=4-way, 8=8-way).
! --- it is an error for 'PIPE_SYM' to exist when making a
! --- master/slave comparison.
!
! --- if the file 'PIPE_NAN' exists, there is no slave and the
! --- master checks that all appropriate fields are free of
! --- NaNs and Infs.
!
! --- if the file 'PIPE_TRACER' exists, there is no slave and the
! --- master checks that all appropriate tracers are non-negative
! --- and compares temperature to any "temperature" tracer.
!
! --- if the file 'PIPE_DEBUG' exists then debugging printout
! --- is produced for point itest,jtest (>0, see blkdat.f).
! --- if itest=-1 the min/max/iospycnal of th3d are printed.
! --- if jtest=-1 the basin-wide means are printed.
! --- this works with or without a pipe for comparison.
! --- if the file 'PIPE_DEBUG_ISO' exists then min/max/iospycnal of th3d
! --- are printed (alternative to itest=-1 that allows point printout).
! --- if the file 'PIPE_DEBUG_SUM' exists then basin-wide means are
!--- printed (alternative to jtest=-1 that allows point printout).
! --- if the file 'PIPE_DEBUG_MAS' exists then "dp", rather than
!--- the usual "dp'" is used as the vertical coordinate.
!
! --- if the file 'PIPE_DEBUG_SSH' exists then debugging printout
! --- is produced for SSH at point itest,jtest. in addition, SSH
! --- is checked everywhere for NaN and/or Infs.
! --- this works with or without a pipe for comparison.
!
! --- the 'PIPE_MASTER' and 'PIPE_SLAVE' files contain the location
! --- of an existing named-pipe. the 'PIPE_SHIFT' file contains the
! --- periodic shift to apply on the slave. the 'PIPE_SYM' file
! --- contains the kind of symmetries to test for. the contents of
! --- the 'PIPE_DEBUG' and 'PIPE_DEBUG_SSH' files are ignored.
!
! --- call 'pipe_compare' (from master and slave) anywhere in the code
! --- to check whether data stored in a single array are identical
!
! --- call 'pipe_compare_sym1' anywhere in the code to check whether
! --- data stored in a single p-grid array are symmetrical.
! --- note that this can be used in place of 'pipe_compare', since
! --- it will call the latter in master/slave mode.
!
! --- call 'pipe_compare_sym2' anywhere in the code to check whether
! --- data stored in vector u and v grid arrays are symmetrical.
! --- note that this can be used in place of 'pipe_compare', since
! --- it will call the latter twice (for u and v) in master/slave mode.
!
! --- call 'pipe_comparall' (from master and slave) after major routines
! --- to check whether data stored in all major arrays are identical or
! --- symmetric.
