single.dvi 26 Concurrency: An Introduction Thus far, we have seen the development of the basic abstractions that the OS performs. We have seen how to take a single physical CPU and turn it into multiple virtual CPUs, thus enabling the illusion of multiple pro- grams running at the same time. We have also seen how […]

single.dvi 5 Interlude: Process API ASIDE: INTERLUDES Interludes will cover more practical aspects of systems, including a par- ticular focus on operating system APIs and how to use them. If you don’t like practical things, you could skip these interludes. But you should like practical things, because, well, they are generally useful in real life;

When your web browser connects to a web server somewhere else on the planet, it is par- ticipating in what seems to be a simple form of a client/server distributed system. When you contact a modern web service such as Google or
CS 111: Operating System Principles Lab 3 Hash Hash Hash 1.0.3 Jon Eyolfson May 10, 2021 Due: May 21, 2021 at 8 PM PST In this lab you’ll be making a hash table implementation safe to use concurrently. You’ll be given a serial hash table im- plementation, and two additional hash table implementations to modify.

single.dvi 10 Multiprocessor Scheduling (Advanced) This chapter will introduce the basics of multiprocessor scheduling. As this topic is relatively advanced, it may be best to cover it after you have studied the topic of concurrency in some detail (i.e., the second major “easy piece” of the book). After years of existence only in the high-end
single.dvi 9 Scheduling: Proportional Share In this chapter, we’ll examine a different type of scheduler known as a proportional-share scheduler, also sometimes referred to as a fair-share scheduler. Proportional-share is based around a simple concept: instead of optimizing for turnaround or response time, a scheduler might instead try to guarantee that each job obtain a
