A process executes the sequence of machine-level instructions s1, s2, and s3. Another process executes the sequence r1 and r2. (a) Determine all possible interleavings of the instructions when the processes run concurrently.

Step 1
If process 1 starts first, the first instruction will be s1. After that, there are two possibilities: either process 1 continues with s2 or process 2 starts with r1. This gives us two possible sequences: s1-s2-s3-r1-r2 and s1-r1-r2-s2-s3. Show more…

Assuming that two concurrent processes are trying to update a variable C by adding a value V. Assume that the current value of C is 17. Process A is adding the value 39, and Process B is subtracting 9. Show the possible final values based on the interleave between processor machine instructions.

Consider the cyclic process described by Figure $P 12.28$ . If $Q$ is negative for the process $B C$ and $\Delta U$ is negative for the process $C A,$ determine the signs of $Q, W,$ and $\Delta U$ associated with each process.
