1. Consider a system of 9 processes, P={p1,,p9}. Associated with the system are 6 memory cells, M={M1,,M6}. The domain and range for each process is given in the following table: In addition, you are given the following precedence relation: ={(P1,P2),(P1,P6),(P2,P3),(P2,P4),(P2,P5),(P3,P6),(P3,P8),(P4,P6), (P4,P7), (P5,P7), (P5,P8), (P6,P8), (P6,P9), (P7,P9), (P8,P9)\} a. Construct the Precedence Graph (not containing any redundant edges; also modify accordingly). Use PowerPoint, diagrams.net, or any other app to draw the graph. (15 points) b. Is the system above determinate for all interpretations of its processes? If it is not, add to necessary elements to make it determinate (no graph drawing needed). Explain all of your reasoning. (20 points) 2. In the first problem, there were 9 processes, many of which were listed as pairs under the precedence relation. Suppose we are now dealing with a system of only 5 processes named P1 through P5. You are given a set of constraints that are expressed by the following precedence relation: ={(P1,P3),(P1,P5),(P2,P4),(P3,P4),(P4,P5)} Provide pseudocode for each of those 5 processes to show how you can use semaphores to enforce these constraints (i.e., the precedence relation ). Also, you must initialize these semaphores correctly (15 points)
