<tt>Right, the default for maxblocks could be 1000. Nevertheless,
this is a large number especially taking into account tat
nxb=nyb=8 is the default. and you are using the USM solver.<br>
<br>
There are two ways around it.<br>
<br>
Set maxblocks to much smaller number. This effectively robs you of
adaptivity, but you cannot really run adaptive simulations with
large blocks.<br>
<br>
Alternatively, if you don't need AMR at all, decompose you domain
into a modest number of medium-sized blocks, e.g.,<br>
<br>
-maxblocks=64 -nxb=64 -nyb=64.<br>

<p>Where does the 2000 come from?</p>
<p>Maxblocks is auto set to 1000.</p>

<p>The point is I am reading in an external grid that is 512x512

<p>Hmm, somehow Flash is statically allocating more than the
Linux 2GB limit. I'm surprised that anything is statically
allocated.

<p>I did a parallel compile but assuming (for debugging

512 by 512. It will not compile at this size and I get an
