<h2>

<a NAME="Graph"></a>Graph partitioning</h2>
|
||
|
|
|
||
|
|
<p>Zoltan performs graph partitioning when the <i>LB_METHOD</i>
|
||
|
|
parameter is set to GRAPH.
|
||
|
|
Zoltan provides three packages capable of partitioning a graph. The
|
||
|
|
package is chosen by setting the GRAPH_PACKAGE parameter.
|
||
|
|
Two packages (ParMetis and Scotch) are external packages and not
|
||
|
|
part of Zoltan but accessible via Zoltan. The last package is
|
||
|
|
PHG, Zoltan's native hypergraph partitioner. PHG will treat
|
||
|
|
the graph as a regular hypergraph with edge size two.
|
||
|
|
Since PHG was designed for general hypergraphs, it is usually
|
||
|
|
slower than graph partitioners but often produces better quality.
