A.死锁预防(Deadlock Prevention):确保系统永远不会进入死锁状态B.死锁避免(Deadlock Avoidance):在使用前进行判断,只允许不会出现死锁的进程请求资源C.死锁检测和恢复(Deadlock Detection and Recovery):在检测到运行系统进入死锁状态后,进行恢复D.由应用进程处理死锁:通常操作系统忽略死锁相关...
a combination of these techniques might be used in a hierarchical approach. For example, process termination might be used as a first resort, followed by resource preemption if possible, and finally, rollback as a last resort. Additionally, prevention and avoidance techniques are often preferred ov...

The prevention algorithm is based on an intensive use of the structure of the Petri net model. The avoidance algorithms correspond to improvements to the well-known Banker's algorithm introduced by Dijkstra in the framework of Operating Systems. 1 Introduction In [1] we proposed a new method ...

Deadlock, Livelock, and Starvation JoséDuato, ...LionelNi, inInterconnection Networks, 2003 Deadlockis by far the most difficult problem to solve. This chapter is almost completely dedicated to this subject. There are three strategies for deadlock handling: deadlockprevention, deadlockavoidance, ...

死锁避免(Deadlock Avoidance)利用额外的先验信息,在进程请求分配资源时判断分配是否可能造成死锁,有可能则不分配。...死锁检测和恢复(Deadlock Detection & Recovery)监测到死锁后用结束部分进程、强制释放资源或回滚等方法解除死锁。
