Dec 12, 2023 · Busy waiting is required in operating system for achieving mutual exclusion. Mutual exclusion is used for preventing the processes from accessing the shared resources simultaneously. In operating system the critical section is defined as a program code in which concurrent access is avoided.
Aug 17, 2023 · Although inefficient, busy waiting can be beneficial in mutual exclusion if the waiting time is short and insignificant. Additionally, busy waiting is quick and simple to understand and implement.
May 20, 2024 · Mutual Exclusion is a property of process synchronization that states that “no two processes can exist in the critical section at any given point of time”. The term was first coined by Dijkstra.
Good mutual exclusion methods must satisfy all of the following conditions: Mutual Exclusion with Busy Waiting. A. Disabling Interrupts - (a hardware solution) Process disables all interrupts before entering critical section and re-enables them on leaving it. Disadvantages: unwise to allow user process to this ability (should be privileged)
Mutual exclusion - If one process is executing their critical section when the other wishes to do so, the second process will become blocked by the flag of the first process. If both processes attempt to enter at the same time, the last process to execute "turn = j" will be blocked.
Also, if a process halts during its critical section, control will never be returned to another process, effectively halting the entire system. A more elegant method for achieving mutual exclusion is the busy-wait. Busy-waiting is effective for both single-processor and multiprocessor systems.
May 24, 2019 · One of those algorithms is Mutual Exclusion. The name sounds complicated, but the concept is simple; 1 process working IN the critical region, the others keep waiting.
