Sample Generation
\end{center}
\begin{itemize}
\item Generate random samples.
\item iWarp produces the samples and sends\\
      via HIPPI to the C90
\item HIB physically connected at 4 points in the array
\item Results
\begin{enumerate}
\item iWarp: 1450K samples/sec
\item alpha: 185K
\item Sun 4/330: 20K samples/sec
\end{enumerate}
\end{itemize}

\begin{center} 
Sending Data over Hippi
\end{center}
\begin{itemize}
\item iWarp $\rightarrow$ C90 --- Michael Hemy's HIB\\
      routines.
\item C90 $\leftrightarrow$ CM2 --- PSC supplied DHSC\\
      routines.
\begin{enumerate}
\item Advantages:  synchronization, data\\
                   conversion, moderation
\item Disadvantages: inflexible, high latency due to PVM
\end{enumerate}
\end{itemize}
\end{slide}

\begin{center} 
Application Results
\end{center}
\begin{itemize}
\item Successful completion on small\\
      cost matrices.
\item Computation limited on iWarp (6MB/s)
\item Problems w/ larger cost matrices
\begin{enumerate}
\item Insufficient space on C90.
\item Pipelining
\end{enumerate}
\end{itemize}
