5. Introduction to the Subject Distributed Systems Principles and Paradigms Assignment 1  Multi-Threaded Dictionary Server – Design and Implementation of a Simple Multi-Threaded Distributed System Supporting Access to a Remote Dictionary  Aim: – To Enhance Understanding of Socket Programming and Multi- Threading – Gain experience in implementing a simple distributed, client server application. – “Using a client-server architecture, design and implement a multi-threaded server that returns the meaning of a word as stored in a remote dictionary.” – Do some smart design/architecture (networking, storage)!

6. Introduction to the Subject Distributed Systems Principles and Paradigms Assignment 2  Distributed Appliaction Projects – Distributed Race Car (a.k.a, Network Game) – Distributed, Shared White Board  Team Size: – 2 (Strongly recommended) – You choose your own partner.  You are given a chance to show some creative thinking / architecture (e.g. “do I use client/server or P2P”, “TCP or UDP”, etc)  Multi-stage project, assessed at each stage

7. Introduction to the Subject Distributed Systems Principles and Paradigms Computational Resources  Dept. Computing Resources: – You all have access to many servers by now? – Talk to technical staff for details and support. – Use for simple assignments and learning.  CLOUDS Lab Computing Resources: – Mainly for projects. – Lab exercises/assignments requiring special software setup by Lecturer. – Lecturer is responsible for providing support.  Microsoft.NET Lab (Lab 217) – Some may be able to do project based on.NET if you learn.NET concepts yourself.

10. Introduction to the Subject Distributed Systems Principles and Paradigms Presentation Slides  Usually on the web before lecture  They may be updated slightly a day before the lecture to reflect recent developments – Lecturer is happy to print and distribute them in the class as an additional service (at no cost) whenever possible. – No need to read beforehand if you don’t want to!  Mostly derived from the text book. – Please buy prescribed textbook.  Good ideas and figures from alternative text book or reference may also be used.

11. Introduction to the Subject Distributed Systems Principles and Paradigms Why study distributed computing now?  Master of Engineering in Distributed Computing – Huge interest in DS (mostly Web and Internet) Application Services Portals – Some examples Microsoft.NET HP Adaptive Enterprise Oracle – Oracle 10g IBM – On Demand Academic R&D worldwide: Grid computing, e- Science, etc. National Grid application programs – e-Science/UK, e-Research/Australia, Grids – Asia and Europe, Cyber infrastructure in USA – Aims: to convey insight into, and knowledge of the principles and practice underlying the design of distributed systems. to enable you to evaluate existing systems or design new ones.

12. Introduction to the Subject Distributed Systems Principles and Paradigms 433-652 DS Subject Overview  Subject Layout – Part I: Foundations – approx. 5 weeks Introduction, System Models, Inter-process Communication, Socket and Thread Programming – Part II: Programming and Principles – 4 weeks Distributed Objects and Programming, Operating System support services, Distributed Shared Memory Systems – Part III: Paradigms/Platforms - 3 weeks: RMI, CORBA, Kerberos, NFS etc. taught during Part I & II Distributed File Systems, Security and Naming Services Depth of some parts may be reduced as the Dept. has dedicated subjects on some of these topics: - Distributed Algorithms, - Software Systems Security, - Cluster and Grid Computing, - High-Performance Database Systems.

13. Introduction to the Subject Distributed Systems Principles and Paradigms What do we expect from you?  Regular attendance of lectures – Pay full attention, – Be enthusiastic, fully committed to learn new things, – Ask questions during the class, – Participate in discussion.  Study Approach – Study the topics along the way – Review previous lecture material before coming to the class – Read the related subject text book  Assignments – Start working on assignments right from the day they are announced and submit on time. – Be a Team player during Group Project.  Communication – Discuss your concerns with the lecturer early. – Don’t take out your frustrations on me during QoT
