  This is version 2.11 of the Model Coupling Toolkit (MCT).

  Our purpose in creating this toolkit is to support the construction
  of highly portable and extensible high-performance couplers
  for distributed memory parallel coupled models.

  REQUIREMENTS:

  Building MCT requires a Fortran90 compiler.

  A full MPI library is now optional.  To compile without MPI, add
  --enable-mpiserial to the configure command below.  Note that
  not all the examples will work without MPI.  See mpi-serial/README
  for more information.


  The MCT library builds and the examples run on the following
  platforms/compilers:

  Linux: Portland Group, Intel, gfortran, Absoft, Pathscale, Lahey, NAG
  MacOSX: gfortran
  IBM (AIX) xlf
  IBM BlueGene (see PLATFORM NOTE below)
  NEC
  Fujitsu

  Running some of the examples requires a full MPI installation with mpirun
  Memory requirements are modest.

######################################################################
  BUILD INSTRUCTIONS:

  In the top level directory (the location of this README):
	> ./configure
	> make

  "make examples" will build the example programs.

  BUILD HELP:
  Try "./configure -help"  for a list of options.

  The correct Fortran90 compiler must be in your current path.
  A frequent problem on Linux is when more than one F90 compiler
  is in your path and configure finds one and later finds mpif90
  for another.

  Example: If configure has trouble finding the correct F90 compiler:
    > ./configure FC=pgf90.

  You can also direct configure through environment variables:
    > setenv FC xlf90
    > ./configure

  If the build fails, please do the following:
    > ./configure >& config.out
    > make >& make.out
  and send us config.out, make.out and config.log (which is produced by the
  configure command)

  PLATFORM NOTES:
  On a BlueGene, use:
  >  ./configure FC=bgxlf90_r CC=mpixlc_r MPIFC=mpixlf90_r (can also use versions without _r)

######################################################################
  INSTALLATION INSTRUCTIONS:

  "make install" will copy the .mod files to the /usr/include directory
  and the *lib.a files to /usr/lib.   To override these choices, use
  "-prefix" when running configure:
       > ./configure --prefix=/home/$USER
  With the above option, "make install" will place .mod's in /home/$USER/include
  and *lib.a's in /home/$USER/lib

######################################################################
  BUILDING AND RUNNING THE EXAMPLES

  The programs in MCT/examples/simple require no input.

  The programs in MCT/examples/climate_concur1 and MCT/examples/climate_sequen1
  require some input data in a directory called MCT/data.  The dataset is available with MCT
   or separately from the website.

  To build them, type "make examples" in the top level directory or
  cd to examples and type "make".

######################################################################

  Both MCT and MPEU source code are self-documenting.  All modules
  and routines contain prologues that can be extracted and processed
  into LaTeX source code by the public-domain tool ProTeX.  ProTeX is
  included in the MCT source and available from:
  https://gmao.gsfc.nasa.gov/software/protex/

  You can build the documentation with protex and latex by following
  the directions in the doc directory.
