Given the following state for the Banker's Algorithm

5 processes PO through P4

3 resource types before assigning to any process. A has 5 instances: B has 6 Instances. C has 8 instances and D has 4.

Allocation: the resources currently assigned to each process

Max Claim: The maximum number of resource instances a process will need in order to complete.

Determine the available vector

Solutions

Expert Solution

Allocated matrix = (5, 6, 6, 2)

A has 5 instances, B has 6 instances, C has 8 instances, D has 4 instances which is (A, B, C, D) = (5, 6, 8, 4)

Available vector = (5, 6, 8, 4) - (5, 6, 6, 2)

Available vector = (0, 0, 2, 2)

Now calculate need

Need = Max - Allocation

Answer : "yes, p2, p0, p1, p3, p4"

Implement the Banker's algorithm for deadlock avoidance, that works on a given set of N processes and M resource types (N<10,M<10). Use C/C++/C# or Java for the implementation, with a simple text interface, where the user enters only the name of the input file (text only). The program reads all the necessary input data from that file. The input data and result is then displayed on the screen. You may use your program to validate the example you gave in...

Deadlocks. The Banker's algorithm is used for deadlock avoidance. Consider the state of resource availability and allocation defined by the following matrices.(1) Assuming that the total amounts for resources R1, R2, and R3 are 10, 2, and 10, should a new request to the Banker's algorithm by process P3 to acquire one additional resource from R1 and one additional resource from R3 be approved or denied?

Consider the following algorithm to find the kth largest element of a given array A of n numbers. We pick every fifth element of A and place them in the array B. We find the median of B recursively, and use this median of B as a pivot to partition the array A. Depending on k and the number of elements that are smaller than the chosen pivot, we recurse into an appropriate subproblem of A.Answer the following questions.Write the...
