域一致性新型锁同步机制的实现

Implement of New Type Lock Mechanism for Scope Consistory

域一致性新型锁同步机制的实现将软件分布式共享存储系统所使用的基于域一致性协议锁机制以新的方式加以实现。它充分利用 SMP 结构所具有的特点, 以多级方式实现锁同步机制, 在结点内部使用了共享空间来实现锁的进程间信息的传递, 让锁的获得、释放所需消息总量及消息传送次数大大减少, 提高了锁的实现效率, 进而程序的执行速度获得了提高。

The implement of new type lock mechanism for Scope consistory presents a new approach. The implement is full use of SMP property ,and it was applied in a hierarchy way.The communication inside a node can be used by shared memory that is applyed by OS. So the total message quanlity and times about the lock mechanism is decreased ,and the efficieny is improved.
