Deadlock Avoidance using Banker’s Algorithm

Q2: Use the following information and complete the Table, also write down the safe sequence if exist?

Three Resources (R1=4, R2=9, R3=11)

Processes	Allocated Resources R1 R2 R3	Maximum Required Resources R1 R2 R3	Currently Available Resources R1 R2 R3	Remaining Need R1 R2 R3	Safe Sequence
P1	1 4 2	2 4 6
P2	2 1 1	3 2 8
P3	0 0 1	1 2 3
P4	0 0 0	4 4 2
P5	0 0 1	1 3 1

Expert Solution

yes there are exist safe sequence and the safe sequence is P1->P2->P3->P4->P5

process	allocated reso	max require	cur availabe	remaining need	SAFE SEQUENCE
P1	1 4 2	2 4 6	1 4 6	1 0 4	FIRST
P2	2 1 1	3 2 8	2 8 8	1 1 7	SECOND
P3	0 0 1	1 2 3	4 9 9	1 2 2	THIRD
P4	0 0 0	4 4 2	4 9 10	4 4 2	FOURTH
P5	0 0 1	1 3 1	4 9 11	1 3 2	FIVETH

Implement a C++ program to implement the Banker’s algorithm for deadlock avoidance. Number of process 5, number of resources 3 and the number of instances of each given resource is in available. You should complete the functionalities for safe state check and resource request processing. To Do 1. Complete the definition of isSafe function. The function take, the process array, 1D array of available resources, 2D array storing current allocation, and 2D array of current need. The function does not...

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...

Deadlock –Banker’s Algorithm A system has three resource types (A, B, C) and four processes {P1, P2, P3, P4 }. The total units of system resources are: (8, 5, 4) units of A, B and C, respectively. The maximum demands for each process is P1(1,2,3), P2(3,2,1), P3(6,5,4) and P4(4,4,2). The current allocation is: P1(0,1,1), P2(2,2,0) and P3(3,0,1) and P4(1,0,1). (a) Allocation table is given for the 3 processes with the following four columns: PROCESS, ALLOCATION, MAX and NEED. And fill...

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? Explain why or why not(2) Assuming that the total amounts for resources R1, R2,...
