<li>
<a href="https://github.com/sandialabs/Zoltan/releases">Zoltan v3.901</a>
was released in February 2022 as part of Trilinos v13.4.
This release includes capability to serialize a Zoltan struct for communication,
as well as minor tweaks for certain installations of MPI.
<br><br>
<li>
<a href="#ZOLTAN383">Zoltan v3.83</a>
was released in January 2016 as part of Trilinos v12.6.
This release includes only minor software changes.
See more details <a href="#ZOLTAN383">below</a>.
<br><br>
<li>
<a href="#ZOLTAN382">Zoltan v3.82</a>
was released in May 2015 as part of Trilinos v12.
This release includes only minor software changes.
See more details <a href="#ZOLTAN382">below</a>.
<br><br>
<li>
<a href="#ZOLTAN381">Zoltan v3.81</a>
was released in November 2014 as part of Trilinos v11.12.
This release upgrades Zoltan's interface to ParMETIS v4 and Scotch v6.
See more details <a href="#ZOLTAN381">below</a>.
<br><br>
<li>
<a href="#ZOLTAN38">Zoltan v3.8</a>
was released in October 2013 as part of Trilinos v10.11.
This release uses Trilinos' BSD license! See more details <a href="#ZOLTAN38">below</a>.
<br><br>
</li>
<li>
<a href="#ZOLTAN36">Zoltan v3.6</a>
was released in September 2011 as part of Trilinos v10.8.
This release includes new recoloring capability in Zoltan's <a href="ug_html/ug_color.html">coloring</a> algorithms.
Zoltan's hierarchical partitioning algorithm was
also updated for greater efficiency.
We have updated our third-party library support to include
PT-Scotch versions up to 5.1.12 and ParMETIS v3.1 and v4.0.
<br><br>
</li>
<li>
<a href="#ZOLTAN35">Zoltan v3.5</a> was released in March 2011. This release
differs from the Trilinos 10.6 release by including the following features:
<ul>
<li>
Fix in Fortran90 interface that causes compilation and run-time problems
with gcc 4.5 and later when compiler optimization is enabled.
</li>
<li>
Support for 64-bit builds of Zoltan, enabling operation on more than 2B objects.
See details for building in the <a href="ug_html/ug_usage.html">Zoltan User's Guide</a>.
</li>
<li>
Faster graph builds for very specific input types. See parameter
<a href="ug_html/ug_graph_build.html">GRAPH_BUILD_TYPE</a>.
</li>
</ul>
<br><br>
</li>
<li>
The Zoltan team received the "Best Algorithms Paper Award" at the
<a href="https://www.ipdps.org">2007 International Parallel and Distributed
Processing Symposium (IPDPS07)</a>
for their paper
"Hypergraph-based Dynamic Load Balancing for Adaptive Scientific Computations."

The <b>Zoltan Library</b> provides critical data-management services
to a wide range of parallel applications.&nbsp; Zoltan includes many utilities
needed by unstructured and/or adaptive parallel applications. These utilities
include
<ul>
<li>
a suite of <a href="ug_html/ug_alg.html"><b>dynamic load-balancing and
parallel partitioning tools</b></a> that
distribute data over sets of processors,
</li>
<li>
<a href="ug_html/ug_interface_mig.html"><b>data migration tools</b></a> that simplify movement of data to new parts,
</li>
<li>
<a href="ug_html/ug_interface_order.html"><b>
parallel graph/matrix ordering algorithms</b></a> for fill-reducing matrix
ordering, including interfaces to PT-Scotch (LaBRI/INRIA-Bordeaux) and
ParMETIS (U. Minnesota),
</li>
<li>
<a href="ug_html/ug_color.html"><b>parallel graph coloring</b></a> including
distance-1 and distance-2 coloring,
</li>
<li>
<a href="ug_html/ug_util_dd.html"><b>distributed data directories</b></a>
that efficiently locate off-processor data,
</li>
<li>
an <a href="ug_html/ug_util_comm.html"><b>unstructured communication
package</b></a> that greatly simplifies interprocessor
communication, and
</li>
<li>
a <a href="ug_html/ug_util_mem.html"><b>dynamic memory debugging
package</b></a> for memory-debugging
on state-of-the-art parallel computers.
</li>
</ul>
Zoltan's object-oriented interface is easy-to-use and enables
Zoltan to be used by a number of different applications.&nbsp; 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.&nbsp;</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>
<!------------------------------------------------------------------------->
<b>Advantages of using Zoltan in applications:</b>
<ul>
<li>
Zoltan's <a href="ug_html/ug_interface.html">object-oriented interface</a>
is clean and easy to use in applications.</li>
<li>
A <a href="ug_html/ug_alg.html">suite of load-balancing algorithms</a>
is included in Zoltan;
<br>try them all to see what works best in your application.</li>
<li>
<a href="ug_html/ug_alg_parmetis.html">Interfaces</a> to the popular
<a href="https://www-users.cs.umn.edu/~karypis/metis/parmetis/">ParMETIS</a>
and <a href="https://staffweb.cms.gre.ac.uk/~c.walshaw/jostle/">Jostle</a> packages are included.</li>
<li>
Application development time can be reduced by using Zoltan's
parallel utilities for
<a href="ug_html/ug_util_comm.html">unstructured communication</a>,
<a href="ug_html/ug_util_mem.html">dynamic memory management</a>,
<a href="ug_html/ug_interface_mig.html">data migration</a>,
and <a href="ug_html/ug_util_dd.html">distributed data directories</a>.
</li>
</ul>
<!------------------------------------------------------------------------->
<b>Advantages of using Zoltan for developing new algorithms:</b>
<ul>
<li>
<a href="dev_html/dev_add.html">New algorithms can be added</a> to Zoltan
in a straightforward manner.</li>
<li>
Zoltan's <a href="ug_html/ug_query.html">object-based interface</a>
provides a simple, general way to get needed application data to the algorithms.</li>
<li>
New algorithms can be compared to high-quality
implementations of <a href="ug_html/ug_alg.html">existing algorithms</a>.</li>
<li>
Zoltan's <a href="Zoltan_phil.html#ZDesign">data-structure neutral design</a>
allows new algorithms to be used easily in many different applications.</li>
