1. COT 4600 Operating Systems Fall 2010 Dan C. Marinescu Office: HEC 439 B Office hours: Tu-Th 3:30-4:30 PM

2. Lecture 1 2 Today:  Class organization  Systems and Complexity Next time  Sources of Complexity Lecture 1 – Tuesday, August 24, 2010

3. Lecture 1 3 Class organization Class webpage: http://www.cs.ucf.edu/~dcm/Teaching/COP4600-Fall2010/ClassIndex.html Textbook:  ``Principles of Computer Systems Design; An Introduction'' by Jerome Saltzer and Frans Kaasohoek. Publisher: Morgan Kaufmann, ISBN 978-0-12-374957-4.

4. Lecture 1 4 The textbook has 6 chapters Systems Elements of Computer System Organization The Design of Naming Schemes Enforcing Modularity with Clients and Services Enforcing Modularity with Virtualization Performance

5. Lecture 1 5 Objectives The COT 4600 class covers basic principles guiding the design and implementation of operating systems. The focus of the class is switched from the discussion on ``how'' operating systems are implemented to the identification of the most important questions the designer of an operating system has to address and ``why'' a solution is better than others.

6. Lecture 1 6 Objectives (cont’d) Another major departure from the more traditional approach in covering operating systems is the emphasize on performance; several lectures cover computer system performance analysis. We also emphasize the ``big picture'' the relationship of operating systems with other subjects from undergraduate curriculum including:  computer architecture,  programming languages,  algorithms,  networking,  databases,  modeling and performance analysis.

7. Lecture 1 7 Assignments There are 6 homework assignments and a class project. A homework consists of 3-5 problems at the end of each chapter in the textbook. The homeworks are due before the start of the class on Tuesdays; you have two weeks from the instant a homework is assigned until its due

8. Class project Write a client and a server for a document sharing system. Demonstrate the functionality of the system.  Phase 1. The system should allow multiple clients to have concurrent read access and exclusive write access to a bounded buffer.  Phase 2. Create a directory and allow the system to support access to multiple documents.  Phase 3. Modify the system to support multiple versions; each client requesting a copy should get the latest version.  Phase 4. Design a graphics user interface supporting a set of basic commands e.g., Read, Write, List Directory. Test the system using several machine with the server and the clients running on different systems. Lecture 18
