\begin{frame}{Wrap-up}
\begin{itemize}
\item PETSc can help you
\begin{itemize}
\item easily construct a code to experiment with ideas
\item scale an existing code base
\item incorporate more scalable or higher performance algorithms
\item attain high performance on a variety of architectures
\item debug and profile a parallel application (not discussed today)
\item package and distribute your code (e.g. graph algorithms, \\
domain decomposition and multilevel solvers), \code{-{}-download-xxx}
\end{itemize}
\item I will be around most of today, find me to discuss
\begin{itemize}
\item new and old features in PETSc
\item performance, scalability, and algorithms
\item design of new codes
\item integration with your existing application
\end{itemize}
