-\frame{\frametitle{Modularization Motivation}
-Simulations are complex, may contain several models at once.\\
-Example: Long Gamma Ray Burst:

-    \begin{center}
-     \includegraphics[width=0.9\textwidth]{supernova_model}
-    \end{center}
-   \column{.5\textwidth}
-   \begin{itemize}
-    \item General Relativity (black hole)
-    \item Relativistic Hydrodynamics (star)
-    \item Microphysics, equation of state (shock wave)
-    \item Neutrino radiation (cooling, heating)
-    \item Magnetic Fields (Jet formation)
-    \item Photon radiation (afterglow)
-   \end{itemize}
-
-  \end{columns}
-}
-
-\frame{\frametitle{Modularization Motivation}
- Added Problems:
- \begin{itemize}
-  \item Example: Einstein Toolkit (not untypical)
-  \item Code 12+ years old
-  \item Grad students leave after 3 productive years
-  \item Most original authors not available anymore
-  \item Developers distributed over many places in several continents
-  \item Most physicists are not good programmers
- \end{itemize}
-}
-
-\frame{\frametitle{Component Architecture}
- \begin{itemize}
-  \item Split program into independent components (as much as possible)
-  \item \textit{Framework} provides glue between these
-  \item Components are developed independently by small groups
-  \item End user assembles all code: no central control, no authorative version
-  \item Framework itself does no real work
-  \item Components don't interact directly with each other
- \end{itemize}
-}
-
-\frame { \frametitle{Cactus History}
-  \begin{itemize}
-   \item Direct descendant of many years of code development in Ed Seidel's group of
-         researchers at NCSA
-   \item 1995, Paul Walker, Joan Masso, Ed Seidel, and John Shalf: Cactus~1.0
-   \item Originally for numerical relativity
-   \item Over the years generalized for use by scientists in other domains
