##############################################
#
# Please choose a compiler. Compiler options are
# usually correct. You might check below.
#
# Available options for the Fortran compiler are:
#
# GNU_G77		->	g77
# GNU_GFORTRAN		->	gfortran
# INTEL			->	ifort
# PORTLAND		->	pgf90
# IBM			->	xlf
# PGI			->	nvfortran
#
# Available options for the C compiler are:
#
# GNU_GCC		->	gcc
# INTEL			->	icc
# IBM			->	xlc
# PGI			->	nvc

##############################################
# Parallel compilation
##############################################
#
# For some compilers you can specify
# parallel execution of some parts of the
# code. This can be specified here. Please
# switch back to serial execution if you are
# in doubt of the results.
#
# If running in parallel you get a segmentation fault
# then you might have to run one of the following
# commands on the command line, before you run
# the model:
#
#	ulimit -a		# gives you the system settings
#	ulimit -s 32000		# sets stack to 32MB
#	ulimit -s unlimited	# sets stack to unlimited
#
# For the Intel compiler you may also try inserting a
# command similar to the following in your .bashrc file:
#
#       export KMP_STACKSIZE=32M
#
# There are two ways of parallelizing. One is OMP
# and the other is MPI. Please note that MPI is
# highly experimental and not recommended to be used
# at this stage.

##############################################
# Partition library for domain decomposition
##############################################
#
# Here you specify the external module to be used
# for the partition of the grid. The software
# should be downloaded and installed separately.
#
# There are different options for the software:
#
#  - METIS: http://glaros.dtc.umn.edu/gkhome/views/metis
#  - ...
#
# The variable PARTSDIR indicates the directory
# where the library and its include files can be found.
# Please leave out the final lib specification.
# This is mandatory only if the library has been
# installed in a non-standard place.
#

##############################################
# Solver for matrix solution
##############################################
#
# Here you have to specify what solver you want
# to use for the solution of the system matrix.
# You have a choice between Gaussian elimination,
# iterative solution (Sparskit), the Pardiso
# solver, and the Paralution solver.
# The gaussian elimination is the most robust.
# Sparskit is very fast on big matrices.
# To use the Pardiso solver you must have the 
# libraries installed. It is generally faster
# then the default method. Please note that
# in order to use Pardiso you must also use
# the INTEL compiler. The option to use the
# Pardiso solver is considered experimental.
# Finally you can use the Paralution solver,
# which allows you to use the GPU. 
# This solver is still in a testing phase,
# it should be faster with large matrices
# and with a good GPU.
# Moreover, it can reduce the CPU usage.
# If you are unsure what solver to use, leave
# the default which is SPARSKIT.

# NetCDF library
##############################################
#
# If you want output in NetCDF format and have
# the library installed, then you can specify
# it here. Normally the place where the netcdf
# files reside can be found automatically. However,
# if the libraries are in some non standard 
# place the directory where the netcdf files
# (include and libraries) reside must also be 
# indicated.
#
# You can normally find the directory by one
# of the following commands:
#   ldconfig -p | grep libnetcdff
#   whereis libnetcdff
#   locate libnetcdff.a
# Do not include the final /lib part of the directory.

# GOTM library
##############################################
#
# This software comes with a version of the
# GOTM turbulence model. It is needed if you
# want to run the model in 3D mode, unless you
# use constant vertical viscosity and diffusivity.
# If you have problems compiling the GOTM
# library, you can set GOTM to false. This will use
# an older version of the program without the
# need of the external library. However, this 
# option is not recommended.
