java memory model

With locking there are a number of optimizations that are simply not allowed because they would break the specification described by the Java Memory Model.

对于锁来说，由于很多优化行为违反了Java存储模型中描述的规范，所以它们是被禁止的。

In the same time, Java Memory Model ( JMM) allows compilers to change the executing order of programs in the optimization progress. This will lead to lots of unexpected errors in multithreaded Java programs.

同时，Java内存模型JMM（Java Memory Model）允许编译器在优化过程中改变程序的执行顺序，这会让多线程Java程序产生许多意想不到的错误。

You can override the memory model by setting the LDR_CNTRL environment variable yourself before starting the Java launcher.

您可以覆盖内存模型，方法是在启动Java启动程序之前设置LDR CNTRL环境变量。

Achieving thread-safety without locking is tricky and requires a deep understanding of the details of the Java Memory Model.

要在不使用锁的情况下取得线程安全性需要一定的技巧性，并且需要对Java内存模型（Java Memory Model）的细节有深入的理解。

Based on the deficiency, this paper analyses Java Memory Model ( JMM), the reason for DCL invalidation and the interior mechanism of "ThreadLocal". The strategy to design the object of class by singleton model is proposed.

针对这些不足，本文结合实例分析了Java内存模型（JMM）、DCL失效原因以及ThreadLocal的内部运行机制，给出了将类的对象设计成Singleton模式的策略。

We can extend the lock granularity technique to handle this situation, although we must be careful as there are some potential Java Memory Model ( JMM) hazards associated with this approach.

我们可以扩展锁粒度技术以应付这种情形，尽管我们必须很小心，因为有与这种方法有关的一些Java内存模型（Java Memory Model，JMM）危害。
