Here is the code that we experimented with in class.
This page documents what we do in class. It contains code that we will discuss in class, reading assignments, simple homework exercises that you can work on for practice and exam preparation (not for credit), links to other sources of information, etc.

Today we will look at some thread pool examples.
Class will meet at 3:30 on campus in the CLO building, Room 210.
Today we will look at an implementation of bounded buffer using Java's built in monitor (instead of using distinct locks and condition variables).
Class will meet at 3:30 on campus in the CLO building, Room 210.
Here are the Java API's versions of "bounded buffers".

Today we will look at this example of a bounded buffer.
Because of the weather, class met at 3:30 using the Zoom application.
Here is a link to today's video lecture.
When you are connected to the campus network, download Chapter 3 from the following book (you need to be on campus to access this book). The chapter is about the wait() and notify() methods and their use in the producer-consumer problem.
Read the following chapter about condition variables and bounded buffers from this operating systems textbook.
Class will meet at 3:30 on campus in the CLO building, Room 210.
Read Sections 4.1 - 4.6 from the following chapter about synchronization, and the producer/consumer problem, from this operating systems textbook.
Today we will continue with examples of the producer/consumer synchronization problem.
Class will meet at 3:30 on campus in the CLO building, Room 210.

Class will meet at 3:30 on campus in the CLO building, Room 210.
Today we will look at Java examples of race conditions and critical sections. Be sure to compare them to the analogous Pthread examples.
Here is a link to today's video lecture.
NOTE: Starting Tuesday of next week, we will be meeting in a classroom on campus (we will meet in CLO Bldg, Room 210). When we meet on campus, there will be no Zoom component to the class.
Read about race conditions and synchronization from the following two Java references.
Here is a very general overview of Java threads written by one of the designers of the Java language.
I rewrote many of the Java examples to make them more like the Pthread examples.
Here is a link to today's video lecture.
Here are some simple code examples using Java threads. Be sure to compare them to the analogous Pthread examples.
