What is OS?

Computer systems internals

CPU Mem I/O Devices

Operating Systems

Hardware

Software

Architecture

Application


Why do we learn OS?

To graduate?

To make a better OS or system. • Functionality

• Performance/Cost

• Reliability

• Energy efficiency

To make a new hardware up and running.

To design OS-aware hardware.

To understand computer systems better.

Just for fun!

• Case studies – Linux

– Microsoft Windows

– Solaris

Hands-on projects

• Using Pintos instructional OS


Lectures: Topics

Operating system structure overview

Processes and threads

CPU scheduling

Synchronization

Deadlocks

Memory management

Virtual memory

I/O systems

Storage

Projects: Pintos

What is Pintos?

• An instructional operating system

• Developed by Ben Pfaff @ Stanford U.

• A real, bootable OS for 80x86 architecture – Run on a regular IBM-compatible PC

or an x86 simulator

• The original structure and form was inspired by the Nachos instructional OS from UC Berkeley (Java-based)

• A few of the sources files are derived from code used in the MIT’s advanced operating systems course

• Written in C language (with minimal assembly code)

Slip days

• Each team has 5 “slip” days

• 20% off per day after slip days exhausted

Project grading

• Automatic grader in Pintos

• Demos & oral tests

Lab session


Class Policies (1)

Grading Policy (subject to change)

• Exams: 35%

• Projects: 55%

• Class attendance: 10%


Class Policies (2)

Class Attendance Policy • If you miss one or both of exams, you will fail this

course.

• Do not be late! You should be present in the lecture room when I take class attendance.

• You can miss the class up to “four” times without any penalty. – For unexcused absences and for excused absences as well

• There will be a bonus for students who attend all the classes.


Class Policies (3)

Cheating Policy

• What is cheating? – Copying another student’s solution (or one from the Internet)

and submitting it as your own

– Allowing another student to copy your solution

• What is NOT cheating? – Helping others use systems or tools

– Helping others with high-level design issues

– Helping others debug their code

• Penalty for cheating: – Severe penalty on the grade and report to dept. chair

• Ask helps to your TA if you experience any difficulty!
