<h2>Changes to amrclaw<a class="headerlink" href="#changes-to-amrclaw" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li>Write more digits in <cite>regions.data</cite> file.</li>
<li>Clean up some timing variables.</li>
<li>The maximum number of allowable refined grids is now
variable, and no longer static. If the current maximum
is exceeded, all arrays dimension at maxgr, namely
rnode, node, and listOfGrids (currently set
to 10000) are resized by another 10K.
bndList is also now resizable.</li>
<li>Makefile.amr_2d changed to include the new files to initialize,
restart, and resize the nodal arrays and boundary lists.</li>
<li>The gauges had one some variable that depended
on maxgr. By changing the gauges algorithm, this was
eliminated. The old algorithm did not scale well for
O(10^5) grids and O(100) gauges. The new algorithm just
has each grid patch sort the gauge list to see if it has any
gauges to update. (The old algorithm sorted all grid owners and
their owner gauges, (thus needing to save that mapping), and
therefore was an index lookup by grid number. But again, 10^5
grids needing 2 arrays for only 100 gauges did not make sense.
Also changed the algorithm for finding the best source grid for a
gauge. By starting at the finest level, and rearranging the order
of the loops, once a grid owner was found for a gauge there was no
need to search the rest of the grids.</li>

<li>Makefile.geoclaw changed to include the new files to initialize,

to change to write out maxgr, and call the allocate routines for
the arrays that depend on maxgr. (see amrclaw changes)</li>
