Banker’s Algorithm in C

By | July 14, 2016

Here you will get program for banker’s algorithm in C.

The banker’s algorithm  which is also known as avoidance algorithm is a deadlock detection algorithm. It was developed by Edsger Dijkstra. It is designed to check the safe state whenever a resource is requested. It takes analogy of bank, where customer request to withdraw cash. Based on some data the cash is lent to the customer. The banker can’t give more cash than what the customer has requested for, and the total available cash.  As this algorithm uses bank analogy so named as banker’s algorithm

Banker’s Algorithm in C

The basic data structures used to implement this algorithm are given below.

Let n be the total number of processes and m be the total number of resource types in the system.

Available: A vector of length m. It shows number of available resources of each type. If Available[i] = k, then k instances of resource Ri are available.

Max: An n×m matrix that contain maximum demand of each process. If Max[i,j] = k, then process Pi can request maximum k instances of resource type Rj.

Allocation: An n×m matrix that contain number of resources of each type currently allocated to each process. If Allocation[i,j] = k, then Pi is currently allocated k instances of resource type Rj.

Need: An n×m matrix that shows the remaining resource need of each process. If Need[i,j] = k, then process Pi may need k more instances of resource type Rj to complete the task.
