Abstract

The so-called planetary-scale (or Web-scale) graphs comprise millions of vertices and billions of edges. Such graphs have appeared in several contemporaneous contexts containing information that can potentially explain social behavior (Twitter and Facebook), commercial activities (Amazon), system structures (like roads and computer networks), non-structured information (Wikipedia), information organization (hypertext), to name a few. These graphs are of great analytical value because, besides having a wide range of information, the current trend is that more of such datasets will appear in the following years. For this reason, it becomes necessary the development and the mastering of techniques capable of working with such volumes of information. In this work, we propose to use vertex-centric techniques and asynchronous parallel processing in order to process and to visually represent planetary-scale graphs. The work will based on system GraphChi within the goals of developing analytic-visual techniques that do not demand computational clusters, but, instead, turn the visualization of large graphs accessible to commercial systems with a single processing node.
