chapters/compute: Add more synchronization exercises #156
Description
The current synchronization lab [1] is too verbose and only presents some basic synchronisation scenarios and some of their implementation, but without any concrete usage scenarios. In addition, semaphores and barriers aren't included in the tasks [2]. This makes it difficult for students to design a parallel application, such as the "Parallel Firewall" assignment [3].
The following changes to the synchronization lab [2] are required to fix this issue:
- Add tasks about semaphores and barriers
- Add a task about the producer-consumer model
- Leave the tasks about atomics and TLS at the end of the lab, mostly as bonus.
