Questions and Barriers

• Questions (10m?)
• Puzzler (1h)
• Setting Up (40m)

Questions

First, we'll spend time on questions that you might have had from the C assignment.

Puzzler

Then, we will spend time on the Barrier problem from the Little Book of Semaphores (heretofore known as the LBoS).

Setting Up

Finally, we'll spend any remaining time (I doubt there will be any) on setting up for our homework this weekend.

This weekend, we'll use the POSIX threading API and the semaphores code from PintOS to implement Rendevous and Mutex from our first exploration of the LBoS.
