<para>The Portals LND Linux (<literal>ptllnd</literal>) can be used as a interface layer to communicate with Sandia Portals networking devices. This version is intended to work on Cray XT3 Linux nodes that use Cray Portals as a network transport.</para>
<para><emphasis role="bold">Message Buffers</emphasis></para>
<para>When <literal>ptllnd</literal> starts up, it allocates and posts sufficient message buffers to allow all expected peers (set by concurrent_peers) to send one unsolicited message. The first message that a peer actually sends is (so-called) "<literal>HELLO</literal>" message, used to negotiate how much additional buffering to setup (typically 8 messages). If 10000 peers actually exist, then enough buffers are posted for 80000 messages.</para>
