% An abstract is required for SAND reports.

\begin{abstract}
  The Image Composition Engine for Tiles (\IceT) is a high-performance
  sort-last parallel rendering library.  In addition to providing
  accelerated rendering for a standard display, \IceT provides the unique
  ability to generate images for tiled displays.  The overall resolution of
  the display may be several times larger than any viewport that may be
  rendered by a single machine.  This document is an overview of the user
  interface to \IceT.

\chapter*{Acknowledgement}

I would like to thank Brian Wylie.  It was his ``big ideas'' that got the
ball rolling on the \IceT algorithms and library, and it was his continuing
vision that pushed us on this path to parallel rendering.

I would also like to thank the folks at Kitware, Inc. for adopting the
\IceT library as the parallel rendering library for ParaView.  They also
maintain the \IceT code repository.  Without them, \IceT would probably be
collecting dust on a crashed RAID somewhere.

\chapter{Future Work}

The majority of the development for \IceT was finished by 2004.  Since
then, \IceT has proven to be a stable and versatile library that is
currently being used in several production applications.

The following is a list of potential changes to \IceT.  As of this writing,
none of these are currently under development.  Rather, these are
identified shortcomings of various degrees in \IceT.  These features will
be handled on an as needed basis, assuming the need should arise.

\begin{description}
\item[Update scalability tests.] The scalability tests for \IceT were run
  during its major development, which was several years ago.  At the time,
  64 nodes was considered a pretty enormous big visualization cluster.
  Nowadays, \IceT is sometimes used to run visualization on supercomputers
  containing thousands of processes.  Verifying the scalability of the
  system occasionally is always a good idea.  Also, the
  \index{strategy!reduce}reduce strategy makes assumptions about the
  relative performance of the binary tree and binary swap composition
  algorithms.  The performance point might have changed.  Also, given that
  binary swap is reducing the image with each step, it might be worthwhile
  to switch to binary tree in the middle of the binary swap algorithm.
\item[Render aborts.] In interactive applications, it is often convenient
  to be able to abort a render that takes some time to finish.  Aborting a
  render in the middle of a composite is tricky, because you need to make
  sure that everyone is aware of the abort and that all communication is
  correctly canceled.  This could be partially implemented in \IceT's
  communication layer, but all the strategies still have to be ready to
  quit once a communication is canceled due to an abort (or at the very
  least ignore it without crashing).
\end{description}
