ADVANCED OPERATING SYSTEMS<br>M. Tech (CS###TITLE###AI) Aug

About the Course

This course for M. Tech students is designed to add depth to the concepts learnt in a basic course on Operating Systems and introduce newer, more modern concepts. It is expected that the students are familiar with operating system concepts such as process and memory management. If not, please brush up your concepts!

This Advanced OS course starts with interprocess communication, threads and synchronisation. Emphasis is on practicals where the students solve classic synchronisation problems. It moves on to modern concepts in memory and then to resource management. Students gain experience writing simple device drivers and understand how OS communicates with external devices.

While there is no real textbook for the course, we will be following the material from the following two books in addition to online resources. Any extra material will be suggested in the relevant classes.

Charles Crowley. Operating Systems: A Design-Oriented Approach.
W. Richard Stevens, Stephen A. Rago. Advanced Programming in the Unix Environment, Pearson India, 2005.

Lab Sessions

4 Sep 2025

Lab - I (CS)
(ps command)

This lab makes you explore the ps command in Linux. You will also use the man pages to find out the process states defined in Linux and find information on the processes running in a typical Linux system.

Lab - I (AI)
(ps command)

Lab - II (CS)
(forks, ipc)

This lab has four problems on the use of fork() to create new processes and the use of signals and pipes for interprocess communication.
Reference Material to help you with the Lab if you find the material on Internet too confusing!
