   • Deadlock Ignorance in Operating System

     In this article we will study in brief about what is Deadlock followed by Deadlock Ignorance in Operating System.

     What is Deadlock?  

     If each process in the set of processes is waiting for an event that only another process in the set can cause it is actually referred as called Deadlock. In other words, one event which has to happen by one process with the presence of another process in the process set, this situation is referred as Deadlock.

     Let us understand the above illustrated definition of Deadlock with the help of an example shown in below section.

     Example of a Deadlock: Suppose process A holds resource C and process B holds resource D. Now process A request for resource D and process B request for resource C but none of the process will get these resources as both the resources are already busy with some other process hence neither of them can proceed further. This situation is called Deadlock. 

     After analyzing deadlock with the help of an example (shown above), let us see the four necessary condition which may lead to deadlock, shown in below illustrated section....

   • Deadlock Detection Algorithm in Operating System

     Deadlock Avoidance Algorithm/ Bankers Algorithm:

     What is a deadlock detection algorithm in operating systems? A deadlock detection algorithm is a technique used by an operating system to identify deadlocks in the system. This algorithm checks the status of processes and resources to determine whether any deadlock has occurred and takes appropriate actions to recover from the deadlock.

     The algorithm employs several times varying data structures:  

     Request – An n*m matrix indicates the current request of each process. If...

     • Available – A vector of length m indicates the number of available resources of each type.
     • Allocation – An n*m matrix defines the number of resources of each type currently allocated to a process. The column represents resource and rows represent a process.
     • Request – An n*m matrix indicates the current request of each process. If request[i][j] equals k then process Pi is requesting k more instances of resource type Rj.

   7.3 Methods for Handling Deadlocks. Generally speaking there are three ways of handling deadlocks: Deadlock prevention or avoidance - Do not allow the system to get into a deadlocked state. Deadlock detection and recovery - Abort a process or preempt some resources when deadlocks are detected.
