\begin{itemize}


\vspace*{1.0cm}
\item In house parallel platform for learning, development, production runs

\vspace*{1.0cm}
\item  Inexpensive  (save 30\% per box compared to a commercial PC, save 60% per
commercial  PC  cluster) 

\vspace*{1.0cm}
\item Maintenance (hardware, software) takes time (money)

\vspace*{1.0cm}
\item It's fun and students love to be able to break it and fix it

\begin{large}




\begin{itemize}
\item Computer performance steadily increase -- Price decreasing

\item  Beowulf parallel  computer  systems: off--the--shelf PC components

\item Performance comparable to commercial supercomputers

\item Available in every networked computer  environment (PCs, Macs, UNIX)

\item GeoWulf at UC Davis  (+ \texttt{CML} cluster + \texttt{FatCat} cluster)

\end{itemize}

\begin{large}

  \begin{itemize}

              \vspace*{0.5cm}
      \item It is worth the effort

              \vspace*{0.5cm}
      \item Source code compatible with large DMP machines (can be used for large scale runs)

              \vspace*{0.5cm}
      \item If funding permits, go for packaged deals (scyld, linux networx...) 

              \vspace*{0.5cm}
      \item Always save some funds to build couple machines in house (for fun and to show students
      that there is nothing special about piece of hardware...)
