与通过共享内存与锁交互的线程不同，角色模型利用了“角色”概念，使用邮箱来传递异步消息。
Rather than threads interacting via Shared memory with locks, the actor model leverages "actors" that pass asynchronous messages using mailboxes.
耦合设施是高度集成的组件，通过它们可以创建锁设施和缓冲池等共享资源。
The coupling facilities are highly integrated components that allow for the creation of Shared resources such as locking facilities and buffer pools.
本文中将学习如何使用Boostipc库实现共享内存对象、消息队列和同步文件锁。
In this article, you learn how to use the Boost IPC library to implement Shared memory objects, message queues, and synchronized file locking.
BUFFERS指定共享内存缓冲区的最大数目；LOCKS指定用户会话可以使用的锁的最大数目。
Buffers specifies the maximum number of shared-memory buffers; locks specifies the maximum number of locks available for user sessions.
换句话说，操作系统不会强制您通过锁来共享资源，所以，所有需要该资源的进程都必须协同使用该锁。
In other words, the operating system doesn't enforce the resource sharing through the lock, so all processes that need the resource must cooperate to use the lock.
例如，依赖一个终结方法来释放一个共享资源，例如数据库，的持续锁，很容易引起整个分布式系统突然当掉。
For example, depending on a finalizer to release a persistent lock on a Shared resource such as a database is a good way to bring your entire distributed system to a grinding halt.
我想要很清楚地(说明)：一个旋转锁和一个共享资源是如何被关连在一起的。
I want to be very clear about how a spin lock and a Shared resource come to be associated.
如果一个线程想要从一个共享资源中修改或者读一个值，它必须先获取锁。
If a thread wishes to modify or read a value from a Shared resource, the thread must first gain the lock.
确保你的应用获取共享资源和锁尽量的晚并且尽量早的释放他们以减少争用。
Ensure your application acquires Shared resources and locks late and releases them early to reduce contention.
我们的目标程序使用自旋锁机制来实现线程间对共享内存的互斥访问。
The classic spin lock technology is introduced to implement the mutually exclusive access to Shared memory.
与通过共享内存与锁交互的线程不同，角色模型利用了“角色”概念，使用邮箱来传递异步消息。
With through sharing memory and lock interactive line Cheng is different, role model was used "part" concept, use mailbox will pass asynchronous information.
另外，我们可以定义我们想要的旋转锁数量，来守护我们想要得共享资源。
Furthermore, we can define as many spin locks as we want, to guard as many Shared resources as we want.
另外，我们可以定义我们想要的旋转锁数量，来守护我们想要得共享资源。
