The <b>Zoltan Library</b> provides critical data-management services
|
||
|
|
to a wide range of parallel applications. Zoltan includes many utilities
|
||
|
|
needed by unstructured and/or adaptive parallel applications. These utilities
|
||
|
|
include

||
|
|
<ul>

Zoltan's object-oriented interface is easy-to-use and enables
|
||
|
|
Zoltan to be used by a number of different applications. Zoltan is
|
||
|
|
designed to be flexible and extensible, so different algorithms can be
|
||
|
|
used, compared and added easily.
|
||
|
|
<!------------------------------------------------------------------------->
|
||
|
|
<p><b>Why Zoltan is needed:</b>
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
In some applications, work loads and/or geometric locality change as computations
|
||
|
|
proceed;<br> Zoltan provides <b>dynamic redistribution of data</b> to maintain high
|
||
|
|
performance. </li>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
Adaptive finite element methods</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
Particle methods</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
Contact detection algorithms</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
Multiphysics simulations</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
Adaptive physics models</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
Processors need to <b>track off-processor data's locations</b> in dynamic
|
||
|
|
environments; Zoltan's distributed data directories allow applications to
|
||
|
|
efficiently query and update off-processor data locations.
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
Unstructured and adaptive applications require <b>complicated interprocessor
|
||
|
|
communication</b>; Zoltan's unstructured communication package
|
||
|
|
manages sends and receives for application developers.
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>
|
||
|
|
State-of-the-art parallel computers often do not have sophisticated
|
||
|
|
<b>debugging</b>
|
||
|
|
tools available; Zoltan's dynamic memory management package simplifies
|
||
|
|
location of memory leaks and other memory errors.
|
||
|
|
</li>
|
||
|
|
|
||
|
|
</ul>
