Suppose we are dealing with a system of 5 processes named through You are given a set of constraints that are expressed by the following precedence relation: {(P1, P3), (P1, PA), (P2, P4), (P3, P5)} Provide pseudocode to show how you can use semaphores to enforce these constraints (i.e. the precedence relation ). Note that semaphores are signaling devices, but a process may wait until it receives a signal. This is not mutual exclusion. You must identify the semaphores you use and provide pseudocode for each process. An example of pseudocode that you might create (not correct for this problem): P1_Function { Wait on S4; // Perform P1 tasks Signal S2; } Note: Indicate (using pseudo-code) how one could enforce the precedence relations using semaphores. DO NOT add any extra precedence relations to the solution.

Transcribed Image Text:Suppose we are dealing with a system of 5 processes named through You are given
a set of constraints that are expressed by the following precedence relation:
{(P1, P3), (P1, PA), (P2, P4), (P3, P5)}
Provide pseudocode to show how you can use semaphores to enforce these constraints
(i.e. the precedence relation ).
Note that semaphores are signaling devices, but a process may wait until it receives a
signal. This is not mutual exclusion.
You must identify the semaphores you use and provide pseudocode for each process.
An example of pseudocode that you might create (not correct for this problem):
P1_Function
{
Wait on S4;
// Perform P1 tasks
Signal S2;
}
Note: Indicate (using pseudo-code) how one could enforce the precedence relations
using semaphores. DO NOT add any extra precedence relations to the solution.
