Purpose of the Document Starting with introducing the project idea, presenting research on the idea and explaining the game scenario, the document investigates functionality required in an implementation of the project, t technical details to implement the project, flow of data and use cases. Estimated tasks and an expected time-line for executing the tasks conclude the report. 2. Project Introduction This chapter introduces the reader to the multiplayer online first-person shooter game for Linux Project. A background to the project topic to put the idea into perspective is followed by project definition. Then we explain why such an idea appeals us. Chapter is concluded by a discussion of what is in scope and what is not. 2.1 Project Background Networking among computer systems provides many opportunities for computer application. Internet is the most massive and brilliant example of what networking can bring in. The advent of Internet has radically changed the human society. Internet has become a component of some of the most basic things we do. Information priorly restricted to few has been available to all. Communication became cheap, time-efficient and available in more ways. Very structures of societies have been reshaped, people are befriending and communicating with other people they have never seen, or could never see in the old ways. Entertainment is enhanced and became more social in its own way. Internet is a huge social phenomenon. Nevertheless it is a thing of technology based on networking hardware and computer power. Its functionality is directly related to features and capacity of the technology. Pioneering systems of the Internet used text based communication. More bandwidth, improved network hardware, more CPU/GPU power and practically

  • Support for Mobile Augmented and Synthesized Worlds
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Illinois Digital Environment for Access to Learning and Scholarship Repository Support for Mobile Augmented and Synthesized Worlds December 17, 2007 Won J. Jeon and Roy H. Campbell {wonjeon, rhc}@uiuc.edu Department of Computer Science University of Illinois at Urbana-Champaign Abstract Virtual worlds provide 3D-immersive experiences to users and some of them already have already launched commercial service to users. As computing environment becomes more heterogeneous, more mobile users are anticipated to access the virtual world with their mobile devices. However, still there are challenges and problems to be addressed for mobile users. In this report, state-of-art virtual world platforms are presented and their key features are compared. We compare possible approaches to tackle these problems to support virtual worlds for mobile devices. Transcoding scheme at the proxy is presented and evaluated for a given computing and networking environment. 1. Introduction A virtual world is a computer-simulated or synthesized environment where multiple users inhabit and interact to each other via avatars. The world mimics the real world via simulated real world physics and the persistence of the world comes from maintaining and updating the state of the world around the clock. Historically this concept is rooted from distributed interactive simulation (DIS) and massively multiplayer online role- playing game (MMORPG). DIS is used mainly by military organizations whereas MMORPG has gained huge popularity among general users or gamers. The world is typically represented as 2D or 3D graphics to multiple users.

This paper provides a comprehensive analysis of the practically proven multiserver distribution mechanisms, zoning, instancing, and replication, and the tasks for the game developer implied by them. We propose a novel, high-level development approach which integrates the three distribution mechanisms seamlessly in today’s online games. As a possible base for this high-level approach, we describe the real-time framework (RTF) middleware system which liberates the developer from low-level tasks and allows him to stay at high level of design abstraction. We explain how RTF supports the implementation of single-server online games and how RTF allows to incorporate the three multiserver distribution mechanisms during the development process. Finally, we describe briefly how RTF provides manageability and maintenance functionality for online games in a grid context with dynamic resource allocation scenarios.

    System Problem Detection by Mining Console Logs by Wei Xu A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Computer Science in the Graduate Division of the University of California, Berkeley Committee in charge: Professor David A. Patterson, Chair Professor Armando Fox Professor Pieter Abbeel Professor Ray R. Larson Fall 2010 System Problem Detection by Mining Console Logs Copyright 2010 by Wei Xu 1 Abstract System Problem Detection by Mining Console Logs by Wei Xu Doctor of Philosophy in Computer Science University of California, Berkeley Professor David A. Patterson, Chair The console logs generated by an application contain information that the developers believed would be useful in debugging or monitoring the application. Despite the ubiq- uity and large size of these logs, they are rarely exploited because they are not readily machine-parsable. We propose a fully automatic methodology for mining console logs using a combination of program analysis, information retrieval, data mining, and machine learn- ing techniques. We use source code analysis to understand the structures from the console logs. We then extract features, such as execution traces, from logs and use data mining and machine learning methods to detect problems. We also use a decision tree to distill the detection results to a format readily understandable by operators who need not be familiar with the anomaly detection algorithms. The whole process requires no human intervention and can scale to large scale log data. We extend the methods to perform online analysis on console log streams. We evaluate the technique on several real-world systems and detected problems that are insightful to systems operators.
