Let's say that we design a new Java class called Stuff that has 6 methods in total. Four of these methods will defined as synchronized. Two of the synchronized methods will modify a data structure called foo in the instantiated object. The other two synchronized methods will modify a data structure called bar.

We then create a new Stuff object. It is now concurrently (i.e., at the same time) accessed by 6 different threads. Each of the 6 threads calls a different one of the 6 methods (so all 6 methods are being invoked).

How many of the 6 threads will have to wait/block at this moment?

Which of the following would be considered to be a user level thread (or task or process)?

Let's say that we are trying to support competition synchronization in a producer-consumer environment, in which we have 6 producers and 9 consumers. Moreover, we have decided to use semaphores.

Given this, how big is the range of values associated with the semaphore counter that ensures this form of synchronization. (For example, if [0, 1, 2, 3, 4] were all possible values for the counter, then the range would be of size 5)

Let's say that we have a large computing system that has 64 standard compute cores that can process any type of instruction, and 1 TB (TeraByte) of RAM. This is a single computer, not a group of computers. Moreover, this computer is clearly a multi-processor, as it has 64 cores.

We would classify this kind of system as...
