Webb1 dec. 2024 · For simplicity, in this session I describe two-process mutual exclusion algorithms, where Procs equals {0,1}. I leave their generalizations to an arbitrary number of processes as exercises. The basic property to be satisfied by a mutual exclusion algorithm is mutual exclusion: no two processes are in their critical sections at the … Webb2 juli 2024 · In the Non-Token based mutual exclusion algorithm, a site communicates with a set of other sites to determine who should execute the critical section next. Mutual exclusion is enforced because the assertion becomes true only at the given time. Algorithms that come under Non-token based algorithms are. Lamport algorithm; …
