  2. Deadlock Prevention and Avoidance in a Distributed System (16.5) • Resource-ordering • Banker’s Algorithm • Process Priority • Priority with LC

  3. Priority with LC • Wait-die Scheme • Non-preemptive • newer process gets rolled back • The wound-wait scheme • Preemptive • Older process gets preempted and waits

  4. Examples P1 (5) -> P2 (10) <- P3 (15)
