\section*{Comments on: Parallel Processing and Graphics Techniques
Applied to Artificially Structured Materials}

\subsection*{Section 3.1}

     The first paragraph describing the application domain of LKKR
should probably be rewritten to make it more comprehensible/interesting
to non-experts.  Similarly the second paragraph might benefit from
omitting some of the physics jargon.  (Saying the basic operation is
straightforward, then using terms like ``multiple-scattering theory'',
``local density approximation'' is a bit intimidating, given the forum
where this is going to be presented)

\subsection*{Section 3.2}

     Maybe the general shape of the algorithms could be described
better by giving some high level pseudo-code.  eg
\begin{verbatim}
    for each energy do
      for each k do
        something
\end{verbatim}
might be more lucid than saying in words that there are nested
loops over $E$ and $k$.

     I don't think it says anywhere what $k$-space is (momentum, I
suppose).  But other times $k$ seems to be a number (as in ``$P = k$'', 2nd
para, p6).  Latter case should be \verb$nk$?

\subsection*{Section 4.2}

     It might be interesting to say something about how the slave
program is arranged, so that it can proceed with with it's own
updating, but also accept incoming boundary updates at random
intervals.  Is it polling for incoming communications at regular
intervals?
