2. OSes: 0. Prelim 2 Overview 1. Outline of the Course 2. Meeting Times 3. Workload 4. Course Materials 5. Reading Materials

3. OSes: 0. Prelim 3 1. Outline of the Course v An overview of the design principles behind Operating Systems (OSes). v This course is not about a particular OS (e.g. UNIX), but how OSes in general are designed and constructed.

4. OSes: 0. Prelim 4 Details (may change) v 1. Overview (parts 1–3) –background, computer-system structures, operating system structures v 2. Process Management (parts 4–7) –processes, threads, synchronization, deadlocks, CPU scheduling continued This follows the S&G textbook 5th ed. (see later).

5. OSes: 0. Prelim 5 v 3. Storage Management (parts 8–11) –memory management, virtual memory, file-system interface, file-system implementation v 4. I/O Systems (parts 12–13) –I/O, secondary-storage structure v 5. Distributed OSes (parts 15-18) –distributed file systems. coordination

6. OSes: 0. Prelim 6 Prerequisites v This course requires you to understand quite complex algorithms and pseudo-code (written in a Pascal/C-like language). v The course does not require advanced programming skills.

7. OSes: 0. Prelim 7 2. Meeting Times v I will visiting CSE-TC four times: –Saturday 20th -- Monday 22nd Sept. –Saturday 11th -- Monday 13th Oct. –Friday 24th -- Sunday 26th Oct. –Friday 7th -- Sunday 9th Nov. v Probable teaching schedule each day: –8.30 -- 11.30 (3 * 50 mins; teaching) –13.30 -- 15.30 ( 50 mins teaching; 50 mins lab) continued

8. OSes: 0. Prelim 8 3. Workload (% of total score) v Reading assigments from the S&G textbook. v Lab questions and answers. v Three exercises:30% (each worth 10%) –handed out on the last day of each visit v Exam: 70% (3 hours) –closed book

9. OSes: 0. Prelim 9 Lab Questions and Answers v These questions will not be marked –they are to help you check your understanding v I will go over the answers on the last day of each visit. v The lab questions are similar to the marked exercises and the exam questions.

10. OSes: 0. Prelim 10 Marked Exercise Details v The exercises may ask you to write: –descriptions of OS features –develop algorithms (in pseudo code form) –produce/investigate variants of examples taken from the S&G textbook v You will not be asked to modify an OS. continued

11. OSes: 0. Prelim 11 v I will give you a week to do the exercises, and then you must e-mail me your solutions v If e-mail is a problem then tell me –you can hand in your work at CSE-TC v Each exercise is worth 10% of your final mark.

12. OSes: 0. Prelim 12 4. Course Materials v I will hand out one copy of my slides, the lab questions/answers, and the exercises. v Course materials will also be available at: http://fivedots.coe.psu.ac.th/ Software.coe/OperSys/ –if you print the slides out, use 6 slides to the page to save trees

13. OSes: 0. Prelim 13 Thanks v A few diagrams come from the slides for a similar course: –Comp 305, 1999 School of Maths and Comp. Sci. Victoria Univ. of Wellington, New Zealand http://www.mcs.vuw.ac.nz/courses/ COMP305/ © John H. Hines, 1998 –I’ve included a note with each diagram that I’ve used in my slides.

14. OSes: 0. Prelim 14 5. Reading Materials v The required textbook: Operating System Concepts Abraham Silberschatz & Peter Baer Galvin (S&G) Addson-Wesley, 1998 () Operating System Concepts Abraham Silberschatz & Peter Baer Galvin (S&G) Addson-Wesley, 1998 (5th ed.) v CSE-TC has a copy of the 6th edition –I have brought a copy of the 5th edition with me continued

15. OSes: 0. Prelim 15 S&G (6th edition) v Mostly consists of changes to the later chapters which we will not be studying. v I have added the (small) changes to early chapters, and the new material on threads into my slides. continued

16. OSes: 0. Prelim 16 Which S&G to Use? v You can use either the 5th or 6th edition. v My slides refer to page numbers/figure numbers in the 5th edition. v The 6th edition is rather expensive to buy.

17. OSes: 0. Prelim 17 v Another good textbook: Operating Systems: Design and Implementation Andrew S. Tanenbaum & Albert S. Woodhull Prentice Hall, 1997 –we will not be using it in the course

18. OSes: 0. Prelim 18 Reading Assignments v I will be asking you to read several chapters from S&G (5th ed. or 6th ed) during each of my visits. –by the end you will have read 13/14 chapters v The things you read may appear on the exam.
