Description
1. Introduction
We finished the discussion of threads and general synchronization in class, and you became familiar with the basic OS/161 environment in the first assignment (PA0). In this assignment you will implement synchronization primitives for OS/161 and learn how to use them to solve a synchronization problem. Once you have completed the written and programming exercises you should have a fairly solid grasp of the pitfalls of concurrent programming and synchronization.
To complete this assignment you will need to be familiar with the OS/161 thread code. The thread system provides interrupts, control functions, and semaphores.
Note that in addition to developing non-trivial synchronization code in C, you will need to again do some code reading and directory exploring in OS/161. This is normal. Considering that debugging synchronization programs requires also more time, make sure to allocate sufficient time from the beginning – if you start just a few days before the due date, you are likely to experience significant difficulties.
