Deadlock Prevention and avoidance

Deadlock Prevention and Avoidance

Deadlock Prevention

Deadlock prevention involves ensuring that one of the necessary conditions for deadlock is not met.

Methods for Deadlock Prevention

  • Mutual Exclusion: Make resources shareable.
  • Hold and Wait: Ensure that a process never holds a resource and waits for another.
  • No Preemption: Allow preemption of resources.
  • Circular Wait: Order resources in a linear sequence.

Deadlock Avoidance

Deadlock avoidance involves using algorithms that predict whether a deadlock is possible.

Methods for Deadlock Avoidance

  • Banker's Algorithm: Test for safety by simulating the allocation of resources.
  • Resource Ordering: Order resources in a way that prevents circular waits.


Comparison  Deadlock Prevention Deadlock Avoidance
Approach Prevent one of the necessary conditions Predict and avoid deadlocks
Complexity Less complex More complex
Resource Utilization May lead to underutilization Better resource utilization
