| <p>The Boost Graph Library's class template <a class="reference external" href="http://www.boost.org/libs/graph/doc/adjacency_list.html">adjacency_list</a> supports |
| several selectors that indicate what data structure should be used for |
| the storage of edges or vertices. The selector <tt class="docutils literal"><span class="pre">vecS</span></tt>, for instance, |
| indicates storage in a <tt class="docutils literal"><span class="pre">std::vector</span></tt> whereas <tt class="docutils literal"><span class="pre">listS</span></tt> indicates |
| storage in a <tt class="docutils literal"><span class="pre">std::list</span></tt>. The Parallel BGL's <a class="reference external" href="distributed_adjacency_list.html">distributed |
| adjacency list</a> supports an additional selector, <tt class="docutils literal"><span class="pre">distributedS</span></tt>, |
| that indicates that the storage should be distributed across multiple |
| processes. This selector can transform a sequential adjacency list |
| into a distributed adjacency list.</p> |

| <dl class="docutils"> |
| <dt><strong>ProcessGroup</strong>:</dt> |
| <dd>The type of the process group over which the property map is |
| distributed and also the medium for communication. This type must |
| model the <a class="reference external" href="process_group.html">Process Group</a> concept, but certain data structures may |
| place additional requirements on this parameter.</dd> |
| <dt><strong>LocalSelector</strong>:</dt> |
| <dd>A selector type (e.g., <tt class="docutils literal"><span class="pre">vecS</span></tt>) that indicates how vertices or |
| edges should be stored in each process.</dd> |
