Fall 2017 :: CSE 306 Introduction Nima Honarmand Fall 2017 :: CSE 306 What is an Operating System? (1) All of the stuff between you/your application and the hardware App 1 App 2 App n Kernel Device Drivers Operating System

  1. Fall 2017 :: CSE 306 Introduction Nima Honarmand

  2. Fall 2017 :: CSE 306 What is an Operating System? (1) • All of the stuff between you/your application and the hardware App 1 App 2 App n • Kernel • Device Drivers Operating System • API libraries • UI Processor Disk Memory Network • Our focus is mostly on the kernel and some advanced API

  3. Fall 2017 :: CSE 306 What is an Operating System? (2) • What are the main tasks of an OS? • Abstract the hardware for convenience and portability • Virtualize the hardware to share it among multiple applications • Multiplex the virtualized resources over physical resources • Provide services to applications and users • Process isolation • Inter-process communication • UI • …

  4. Fall 2017 :: CSE 306 Why Operating Systems? • Primary Goal: Demystify how computers work • Lots of abstractions and heuristics between your application and the hardware • A good computer scientist should understand what happens inside the system when one types a command • Secondary: Learn how to write robust programs • OSes like Linux have many users and work on a wide range of hardware • Deal with subtle issues: concurrency, consistency, etc.

  5. Fall 2017 :: CSE 306 About This Course • This course is being revised • After recent changes in CSE 320 and making it a prerequisite • Bear with me as we try to finalize the course syllabus • Some basic OS concepts and API already taught in CSE 320 • We will review those quickly • We will cover more advanced API here • More importantly, we will talk about internal design and implementation issues of Oses • Not covered in CSE 320

  6. Fall 2017 :: CSE 306 Course Format :: Lectures (1) • Basic OS ideas: abstractions, interfaces and algorithms on core issues • Memory • CPU • Multi-threading and synchronization • Storage ― Disks (HDDs and SSDs) and File systems • Networking • Device programming • Inter-process communication and isolation issues • Supplement background on hardware programming

  7. Fall 2017 :: CSE 306 Course Format :: Lectures (2) • Several more recent topics (time permitting) • OS Security • Virtual machines • Advanced file systems • OS in data centers and cloud • Embedded OS issues • High performance networking • etc.

  8. Fall 2017 :: CSE 306 Course Format :: Lectures (3) • Discuss and supplement reading material • An important chance to clarify issues • Questions are encouraged! • I expect you to arrive prepared to answer and ask questions about the reading material • Everything in lectures may appear on the exams, even if not in the book

  9. Fall 2017 :: CSE 306 Course Format :: Labs (1) • Learn by doing • This course is coding intensive • You should know C, or be prepared to remediate quickly • You will learn basic, inline x86 assembly • You must learn to learn on your own/with lab partner • You will make substantial modifications to xv6, a simple x86 Unix variant • Code is written to be easy to understand, but lacks many modern OS features • Challenging work, but a very marketable skill

  10. Fall 2017 :: CSE 306 Course Format :: Labs (2) • We may have one or two advanced user-mode programming labs to use advanced OS API not covered in CSE 320 • Unlike xv6 labs that will be kernel-mode programming • One way or the other, there will be five labs in total • Combination of xv6 and user-mode programming • The exact combination will be determined as we go

  11. Fall 2017 :: CSE 306 Course Format :: Labs (3) • Each student will have a Linux virtual machine on a departmental cluster • Comes with basic development tool chain that you need for the course (GCC, GDB, Qemu, etc.) • You have sudo access and can install new software as you need • You can also use your own laptops but the tech staff won’t support them • See https://compas.cs.stonybrook.edu/~nhonarmand/cours es/fa17/cse306/labs.html for complete details

  12. Fall 2017 :: CSE 306 Lab Late Hours • Each lab team gets 72 late hours • List how many you use in slack.txt • Each hour after these are gone costs 2% on the assignment • It is your responsibility to use these to manage: • Holidays, weddings, research deadlines, conference travel, Buffy marathons, release of the next Zelda game, etc. • 3 Exceptions: illness (need doctor’s note), death in immediate family, accommodation for disability

  13. Fall 2017 :: CSE 306 Lab Teams • Can work alone or as a pair • Choose your own partners • Remains the same for the entire course • Changes only with instructor permission

  14. Fall 2017 :: CSE 306 Readings & Books • Required Readings • Assigned from the OSTEP book + maybe some papers • Should be completed before the lecture • Required reading material may appear on the exams, even if not discussed in lecture • Highly recommended (optional) books • K&R for C programming • Understanding the Linux Kernel (3rd edition) for Linux internals • Advanced Programming in the UNIX Environment (3rd edition), the UNIX bible • Many other references on the website

  15. Fall 2017 :: CSE 306 Other Course Information • TA: TBD • Course website: • compas.cs.stonybrook.edu/~nhonarmand/courses/fa17/cse306 • Syllabus, schedule, homework, etc. posted here • Course newsgroup • Blackboard → Discussions → “General Discussions” Forum • Main venue for all class-related discussions • Sign up ASAP to avoid missing anything • Goal: Everyone can learn from general questions • Do not post code or other solutions here

  16. Fall 2017 :: CSE 306 Prerequisites • CSE 219 (CS III) or CSE 260 (CS B, Honors) • CSE 320 (Systems Fundamentals II) or ESE 380 (Embedded Microprocessor Design I) • The background courses are necessary • In some cases, industry experience is ok • In-class quiz, due before you leave • If you can’t answer 50% of these questions you are not prepared • C programming • Basic Unix command-line proficiency

  17. Fall 2017 :: CSE 306 C Programming • You should have learned C in the prerequisite courses • If you are not sure, you should read “The C Programming Language” by Kernighan and Ritchie (K&R) cover to cover this week • And complete all exercises in the book • If you can do this in the next week or so, you will be prepared to complete this course on schedule

  18. Fall 2017 :: CSE 306 Other administrative notes • Read syllabus completely • Subscribe to the discussion forum on Blackboard • The exams cover lectures , labs , assigned readings and blackboard discussions • Lab VMs aren’t ready yet • Back up your lab work in a private repo • Department provides git repos to let you backup your work • Send an email to rt@cs.stonybrook.edu to have yours activated • Or use BitBucket or Github • Do not make your repos publicly available

  19. Fall 2017 :: CSE 306 Grading What? Points 1 Quiz 0 Labs 60 Midterm exam 20 Final exam 20 Total 100 • Guaranteed grades: [A, A-, B+, …, D, F] = [85, 80, 75, …, 45, <45] • I may use a curve on top of this (but there is no guarantee) • Midterm grade will be the max(midterm, final) • Grades solely determined by your performance in the course • Not whether they are needed for graduation, qualifiers, etc.

  20. Fall 2017 :: CSE 306 Academic Integrity • We take cheating very seriously. It can end your career. • Share ideas but not code • Acknowledge students that give you good ideas • In a gray area, it is your job to stay on right side of line • Never show your code to anyone except course staff • Never look at anyone else’s code (including other universities) • Do not debug each other’s code • Fully read the Academic Integrity text on the website

  21. Fall 2017 :: CSE 306 Questions? Remember: • Hand in the survey • VMs and Lab 1 coming out soon • Reading assigned for next class (Thursday) • No class on Tuesday (Labor Day Observance)

  22. Fall 2017 :: CSE 306 Survey Quiz
