Prove that Ricart andAgrawala’s algorithm prevents deadlock.
What will be an ideal response?
Ricart and Agrawala’s algorithm deals with enforcing mutual exclusion on a single
resource.Therefore, the only deadlock that can occur is communication deadlock, where processes are waiting for messages from other processes before proceeding. In this algorithm,
processes must wait for replies when they request to enter their critical section. For deadlock
to occur, there must be a circular wait, in which each process is waiting for a reply from one
or more other processes before proceeding. But all requests have time stamps, which can be
placed in an absolute ordering. The request with the earliest time stamp must receive replies
from all other processes.Therefore, deadlock can never occur
