3 Thread communication using memory sharing

This chapter covers

• Using inter-thread communication with our hardware architecture
• Communicating with memory sharing
• Recognizing race conditions

Threads of execution working together to solve a common problem require some form of communication. This is what is known as inter-thread communication (ITC), or inter-process communication (IPC) when referring to processes. This type of communication falls under two main classes: memory sharing and message passing. In this chapter, we will focus on the former.

Memory sharing is similar to having all our executions share a large, empty canvas (the process’s memory) on which each execution gets to write the results of its own computation. We can coordinate ...
