(Banker’s Algorithm for Multiple Resource Types) Consider Dijkstra’s Banker’s Algorithm as discussed in Section 7.8, Deadlock Avoidance with Dijkstra’s Banker’s Algorithm. Suppose that a system using this deadlock avoidance scheme has n processes and m different resource types; assume that multiple resources of each type may exist and that the number of resources of each type is known. Develop a version of the Banker’s Algorithm that will enable such a system to avoid deadlock. [Hint: Under what circumstances could a particular process be guaranteed to complete its execution, and thus return its resources to the pool?]
What will be an ideal response?
This is just a matter of using the Banker’s Algorithm for one resource m different times. However, each of the m processes would have to be able to agree on a similar path of execution for all of them to complete.
