the coordinator conculde incorrectly that a deadlock exist and kills some process --------------------------- Detecting a non existent deadlock in distributed system has been referred as false deadlock and it may occur due to communication delay.. ---->Ashok Paranjothi
There are four strategies of dealing with deadlock problem:1. The Ostrich ApproachJust ignore the deadlock problem altogether.2. Deadlock Detection and RecoveryDetect deadlock and, when it occurs, take steps to recover.3. Deadlock AvoidanceAvoid deadlock by careful resource scheduling.4. Deadlock PreventionPrevent deadlock by resource scheduling so as to negate at least one of the four conditions.
In distributed deadlock detection, the delay in propagating local information might cause the deadlock detection algorithms to identify deadlocks that do not really exist. Such situations are called phantom deadlocks and they lead to unnecessary aborts.
The difference is exactly what you have just stated: deadlock prevention is used to stop deadlocks before they happen (to prevent them), while deadlock detection is used to figure out when a process has deadlocked (to detect it).
The word that means hard to detect or describe is elusive.
The antonym for deadlock is agreement.
the paticle that was hard to detect was neutrons because it had no electrical charge.
