<div class="block">Class ScatterLines is a cluster parallel program for scattering the lines in
 one or more text files among the nodes of a cluster parallel computer.
 <P>
 Usage: <TT>java pj2 edu.rit.pjmr.util.ScatterLines <I>nodes</I> <I>host</I>
 <I>port</I> <I>backendfile</I> <I>frontendfile</I> [ <I>frontendfile</I>
 . . . ]</TT>
 <BR><TT><I>nodes</I></TT> = List of one or more comma-separated backend node
 names
 <BR><TT><I>host</I></TT> = Frontend node host name or IP address
 <BR><TT><I>port</I></TT> = Frontend node port number
 <BR><TT><I>backendfile</I></TT> = Backend node file name
 <BR><TT><I>frontendfile</I></TT> = Frontend node file name
 <P>
 The program reads lines from the <I>frontendfile</I> or files on the
 cluster's frontend node. The program scatters those lines among the given
 backend <I>nodes</I>. Each backend node stores its lines in the given
 <I>backendfile</I>. The program distributes the lines to the backend nodes
 such that all the backend files are about the same size. The program chooses
 the backend node to receive each frontend file line in an unspecified manner;
 any line could end up on any backend.
 <P>
 The file data is transferred via a direct socket connection from the frontend
 node to each backend node. The frontend node listens for connections on the
 given <I>host</I> and <I>port</I>. The backend nodes connect to that host and
 port.</div>
