Mutual Exclusion Problem Occurs

By Mandeep Kumar|Updated : July 28th, 2022

Mutual exclusion problem takes place among processes that share resources. It is a program that prevents simultaneous access to shared resources. The concept of mutual exclusion is used in concurrent programming.

Answer: Mutual exclusion problem occurs among processes that share resources.

At a time, only one thread owns the mutex. Hence, when a program starts, a mutex with a unique name is created. Mutex acts as a lock when two threads work on the same data at the same time. It is the most basic synchronization tool. A thread gains a mutex if it is available otherwise it is set to sleep condition. Mutual exclusion is responsible for reducing the latency and busy-waits using queuing and context switches.

To enforce the mutex at the kernel level, the best way is to disable interrupts for the smallest number of instructions. It also prevents the corruption of shared data structures. The mechanism of busy-wait imposes the mutex in the software areas. This is equipped with various algorithms such as Peterson's algorithm, Dekker's algorithm, Lamport's bakery algorithm, Szymanski's algorithm, and the black-white bakery algorithm.

Summary:

Mutual Exclusion Problem Occurs

Mutual exclusion problem occurs when there is a problem with resource sharing.
