$\bullet$& Define information generally to include both CNN headline news
and the insights on QCD gotten from lattice gauge theories.  There are
four broad categories. \\ 
& \\ 
$\bullet$&{\bf Information Production} (e.g., Simulation) \\ 
&$\bullet$ Major concentration of MPP and HPCC at present \\ 
& \\ 
$\bullet$&{\bf Information Analysis} (e.g., Extraction of location of
oil from seismic data, Extraction of customer preferences from purchase
data) \\ 
& \\ 
&$\bullet$ Growing area of importance and Short term major MPP
opportunity in decision support combined with parallel databases \\ 
& \\ 
$\bullet$&{\bf Information Access and Dissemination}---{\em
InfoVision\/} (e.g., Transaction Processing, Video-On-Demand) \\ 
& \\ 
&$\bullet$ Enabled by National Information Infrastructure \\ 
&$\bullet$ Very promising medium term market for MPP but need
the NII to be reasonably pervasive before area ``takes off'' \\ 
&$\bullet$ MPPs used as high performance, high capacity, multi-media
servers \\ 
& \\ 
$\bullet$&{\bf Information Integration} \\ 
& \\ 
&$\bullet$ Integrates Information Production, Analysis and Access,
e.g., \\ 
&\ \ \ \ \ -- Decision support in business \\ 
&\ \ \ \ \ -- Command and Control for Military \\ 
&\ \ \ \ \ -- Concurrent Engineering and Agile Manufacturing \\ 
& \\ 
&$\bullet$ Largest Long Term Market for MPP \\

\item Parallelize by ``data parallelism'' over space of events but no
automatic algorithmic synchronization

between events to ensure synchronization
\item Speedup very problem-dependent
