Web7.2.1. Peterson’s Solution ¶. One approach to solving the problem of critical sections is to employ Peterson’s solution, an algorithmic approach that uses shared memory to declare intentions. Code Listing 7.2 shows the algorithm, which uses a bool array ( flag) to signify a thread’s intent to enter and an int variable ( turn ) to ... WebFormal Definition of Critical Sections. The overlapping portion of each process, where the shared variables are being accessed. Necessary and sufficient conditions for a solution …
