Every single thread has the follow elements: Execution Context:Every thread has a execution context which maintains some basical data about the running of the thread, like windows identity information, pricipal ,etc.One important thing about executio…

There are some synchronization primitives in .NET used to achieve thread synchronization Monitor c# provides System.Threading.Monitor class which cooperates with an objcet to implement locking. Every object has a sync block inside its data stucture,w…

Synchronization means multi threads access the same resource (data, variable ,etc) should not cause a corruption to it.If all methods of a class promise threading synchronization,we call that the class is "Thread Safe". Thread Safety ALL static…

When we want to do a work asynchronously, creating a new thread is a good way. .NET provides two others ways rather than create thread explicitly, that is ThreadPool and Task. ThreadPool Every single CLR maintains a threadpool.There is a queue for us…

在信号量和互斥量例子中,我们都是在程序推出之前利用pthread_join对线程进行再次同步:如果想让thread想创建它的线程返回数据我需要这么做:问题:我们有时候既不需要第二个线程向main线程返回信息,也不想让main线程等待它的结束: 就是说main线程工作的时候创建了第二个thread,第二个thread线程工作到结束,不必向main线程写新的信息:================脱离线程,detaced thread 修改线程属性或调用pthread_detach方法来解决=====…

问题:如何实现死锁. 关键: 1 两个线程ta.tb 2 两个对象a.b 3 ta拥有a的锁,同时在这个锁定的过程中,需要b的锁:tb拥有b的锁,同时在这个锁定的过程中,需要a的锁: 关键的实现难点是3, —— 所以说,死锁也不是那么容易出现的吧.. 实现方式synchronized.Lock 等等 死锁例子1  采用了不同类的两个对象. 原理是: 两个线程尝试进入同一个需要对象锁的方法 package basic.thread; public class DL { public static…

The HPROF Profiler The Heap and CPU Profiling Agent (HPROF)是JAVA2 SDK自带的一个简单的profiler代理,它通过与Java Virtual Machine Profiler Interface (JVMPI) 交互,将profiling信息通过本地文件或socket输出ASCII或二进制格式的流. HPROF可以监控CPU使用率,堆分配统计.除此之外,还可以报告JVM所有监视器和线程的完整的堆的dump状态. HPROF的JV…

Usually, when you develop a simple, concurrent-programming application in Java, you create some Runnable objects and then create the corresponding Thread objects to execute them. If you have to develop a program that runs a lot of concurrent tasks, t…
