-\subsection{Directory structure of model examples}
-
-Each example directory has the following subdirectories:
-
-\begin{itemize}
-\item \texttt{code}: contains the code particular to the example. At a
- minimum, this directory includes the following files:
-
- \begin{itemize}
- \item \texttt{code/packages.conf}: declares the list of packages or
- package groups to be used. If not included, the default version
- is located in \texttt{pkg/pkg\_default}. Package groups are
- simply convenient collections of commonly used packages which are
- defined in \texttt{pkg/pkg\_default}. Some packages may require
- other packages or may require their absence (that is, they are
- incompatible) and these package dependencies are listed in
- \texttt{pkg/pkg\_depend}.
-
- \item \texttt{code/CPP\_EEOPTIONS.h}: declares CPP keys relative to
- the ``execution environment'' part of the code. The default
- version is located in \texttt{eesupp/inc}.
-
- \item \texttt{code/CPP\_OPTIONS.h}: declares CPP keys relative to
- the ``numerical model'' part of the code. The default version is
- located in \texttt{model/inc}.
-
- \item \texttt{code/SIZE.h}: declares size of underlying
- computational grid. The default version is located in
- \texttt{model/inc}.
- \end{itemize}
-
- In addition, other include files and subroutines might be present in
- \texttt{code} depending on the particular experiment. See Section 2
- for more details.
-
-\item \texttt{input}: contains the input data files required to run
- the example. At a minimum, the \texttt{input} directory contains the
- following files:
-
- \begin{itemize}
- \item \texttt{input/data}: this file, written as a namelist,
- specifies the main parameters for the experiment.
+\item \texttt{jobs}: contains sample job scripts for running MITgcm.
- \item \texttt{input/data.pkg}: contains parameters relative to the
- packages used in the experiment.
+\item \texttt{lsopt}: Line search code used for optimization.
- \item \texttt{input/eedata}: this file contains ``execution
- environment'' data. At present, this consists of a specification
- of the number of threads to use in $X$ and $Y$ under multithreaded
- execution.
- \end{itemize}
+\item \texttt{optim}: Interface between MITgcm and line search code.
- In addition, you will also find in this directory the forcing and
- topography files as well as the files describing the initial state
- of the experiment. This varies from experiment to experiment. See
- section 2 for more details.
-
-\item \texttt{results}: this directory contains the output file
- \texttt{output.txt} produced by the simulation example. This file is
- useful for comparison with your own output when you run the
- experiment.
\end{itemize}
-Once you have chosen the example you want to run, you are ready to
-compile the code.
