+\maketitle
+\section{Introduction}
+The following is a brief tutorial on how to use \MMSP and some of it's
+basic functions. If you are unfamiliar with the basics of c++ or how
+to compile and run programs, please refer to the main \MMSP
+documentation or an online C/C++ tutorial.  Some basic help will be
+found in the Makefiles and README files.
+
+\section{The Diffusion Equation}
+
+The diffusion equation relates the time rate of change of a diffusing
+species to the divergence of the gradients in the concentration of the
+diffusing species.
+
+\begin{eqnarray}
+\texttt{c[x,t] = (dt*D/dx**2)*(c[x-1,t-1]-2c[x,t-1]+c[x-1,t-1])+c[x,t-1]}
+\end{eqnarray}
+
+This discrete equation will be used in our example calculation along with
+some MMSP functionality.
+
+\section{Example Codes}
+\label{sec:examples}
+
+\begin{listings}
+\end{listings}
+
+\subsection{1D Diffusion couple, Cish}
+
+The first code is called 1stDiffusion.cpp.  It is found in the
+examples directory under {\tt beginners\_diffusion}. Use the {\tt g++}
+or MPI commands outlined in the introduction to create an executable.
+
+The first thing to notice is that the include, using, and finalize commands are in the same place as in the “Hello World” script handled before.  These are standard for all MMSP codes.  The important MMSP commands are lines 22 and 23:
+\\ 	\textit{grid\textless 1,scalar\textless float\textgreater \textgreater GRID(1,0,length);}
+\\A breakdown of what this line means is:
+\\ 	\textit{grid\textless \# of dimensions,data type\textgreater “GRID name”(Vector quantity, start position, number of terms in first dimension);}
+\\ \begin{itemize} \itemsep1pt \parskip0pt \parsep0pt
+\item The vector quantity is 1 unless the vector data type is used.
+\begin{itemize} \itemsep1pt \parskip0pt \parsep0pt
+\item vectors in MMSP are used to store multiple data values of interest in a single node on the grid
+\end{itemize}
+\item Start position is generally 0, but any number can be used
+\item When using multi-dimensions, the only required change is to add more upper and lower boundaries for each subsequent dimension
+\begin{itemize} \itemsep1pt \parskip0pt \parsep0pt
+\item E.g. for 2 dimensions: \textit{grid\textless 2,scalar\textless float\textgreater \textgreater GRID(1,0,lengthx,0,lengthy)}
+\end{itemize}
+\end{itemize}
+Also, in line 28, the commands “x0(GRID)” and “x1(GRID)” are used. MMSP reads this as the initial and final nodes in the x direction, respectively. x, y, and z commands can be used for this, as well, if the number of dimensions agrees.
+Some other items of interest are:
+\begin{itemize} \itemsep1pt \parskip0pt \parsep0pt
+\item line 43, which defines the steady state boundary conditions
+\item line 45, which refers to the “stability criterion.” This criterion is defined by $D\frac{\Delta t}{(\Delta x)^2}$
+\item line 48, which operates on each point in the GRID
+\item line 49, which defines when GRID gets updated.
+\item line 50, which uses the swap command. The swap command has the syntax:
+\begin{itemize} \itemsep1pt \parskip0pt \parsep0pt
+\item swap(grid to be replaced, grid to use to replace)
+\item In this specific example, the swap command is used to swap all points in GRID1 with all corresponding points in GRID2

+\subsection{1D Diffusion Couple, MMSPish}
+The second time through uses more MMSP functionality. The code for this example is called MMSPDiffusion.cpp in the {\tt beginners\_diffusion} directory. Important differences from the previous example:
+\begin{itemize} \itemsep1pt \parskip0pt \parsep0pt
+\item line 19: instead of GRID2, the MMSP standard name “update” is used for the second grid.
+\item lines 33-36: define the boundary conditions (bulkier in this case, but using other MMSP standard boundaries makes this step very useful).
+\begin{itemize} \itemsep1pt \parskip0pt \parsep0pt
+\item The syntax in line 33, b0(GRID,0), can be generalized to:
+\begin{itemize} \itemsep1pt \parskip0pt \parsep0pt
+\item \textit{boundary condition side(grid to be applied to, dimension to apply the boundary to)}
+\item for this specific example, b0 corresponds to the left-hand boundary, GRID is the grid that the condition is applied to, and 0 corresponds to the 1st (or x) dimension.
+\end {itemize}
+\end {itemize}
+\item line 43: by using the MMSP standard loop, the grid is updated at the correct time without any commands from the operator
+\item line 44: ghostswap command is used in parallel processing - it has no effect when only one processor is used, but is vital when using more than one.

+\subsection{2D Diffusion}
+Now, we have a two dimensional diffusion situation (the upper left quadrant of a square is one species, the other three are another). The code for this example is named MMSPDiffusion2d.cpp and is also located in the {\tt beginners\_diffusion} directory MMSP makes adding dimensions easy, the only necessary changes are
+\begin{itemize} \itemsep1pt \parskip0pt \parsep0pt
+\item line 19 \& 20: change 1 to 2 when setting the number of dimensions in the grid. 
+\item lines 38-45: boundary conditions in both dimensions must be specified
+\end{itemize}
+Thats it.  Those are the only changes that MMSP requires to operate in multiple dimensions.  Other changes include redefining how the grid is set up, but generally the grid comes from a data set, so you will not have to worry about that, and the coefficient representing the diffusion was changed to reflect how the stability criterion changes in multiple dimensions.
