We are organizing a <tt>p4est</tt> summer school
sponsored by the
<a href="https://www.hcm.uni-bonn.de">Hausdorff Center for Mathematics</a>
at the <a href="https://www.uni-bonn.de/">University of Bonn</a>, Germany.
Please see also the school's <a

<h2>Slot 32: ForestClaw : Programming paradigms</h2>
<dl class="spec">
<dt>DC</dt><dd>Donna Calhoun (speaker)</dd>
</dl>
<p class="book">
In this lecture, I will describe the basic programming paradigms used in
ForestClaw.  These include the use of iterators, call-backs, virtual function
tables and encapsulated library functions.  This paradigm makes it possible for
users to design their own library extensions, or customize existing solver and
patch libraries (<a href="slides/forestclaw_t2.pdf">slides</a>).

This lecture will cover the main high-level algorithms exposed by <tt>p4est</tt>,
the ideas and concepts behind them, and their recommended use.
We will discuss mesh modification such as refinement and partition, as well as
more general computational geometry functionality such as searching for remote
objects.
in addition, we will cover helper functionality for exchanging ghost data
and for repartitioning application data after mesh updates.
Altogether, these algorithms are all that's needed to build
a scalable dynamic adaptive numerical simulation on top of <tt>p4est</tt>.
