Consider the following maximum-claim reusable resource system with four processes (PO, P1, P2, P3) and three resource types (RO, R1, R2). The maximum claim matrix C is given by: R1 R2 PO 1 4 P1 3 1 4 P2 5 6 13 P3 1 1 6 where Cij denotes the maximum claim of process i for resource j. The total number of units of each resource type is given by the vector R1 8 15 The current allocation of resources is given by the matrix A RO 5 PO P1 P2 P3 RO 0 2 1 1 RO 4 R1 1 0 4 0 R2 R2 4 3 1 3 Answer the following questions about the system (you do not need to draw any graphs): 2) For the system state shown above, determine if a new request by process P2 for 6 units of resource R2 can be safely granted. (Remark: You can assume that the system state above does not yet take into account this request.). Explain your reasoning. If the request cannot be safely granted, how should the system behave with respect to the request?
