Chapter 20. Starvation

In this chapter, we will discuss the concept of starvation and its potential causes in concurrent programming. We will cover a number of readers-writers problems, which are prime examples of starvation, and we will simulate them in example Python code. This chapter will also cover the relationship between deadlock and starvation, as well as some potential solutions for starvation.

 

The following topics will be covered in this chapter:

  • The basic idea behind starvation, its root causes, and some more relevant concepts
  • A detailed analysis of the readers-writers problem, which is used to illustrate the complexity of starvation in a concurrent system
