[Java concurrent][Collections]

同步容器类同步容器类包括Vector和Hashtable,二者是早期JDK的一部分.以及一些在JDK1.2中添加的可以由Collections.synchronizedXxx等工厂方法创建的. 这些类实现线程安全的方式是,将它们的状态封装起来,并对每个公有方法都进行同步(synchronized),使得每次只有一个线程能访问容器的状态. 同步容器类在一些情况下,可能需要额外的客户端加锁来保护复合操作.eg: public static Object getLast(Vector list) {…

[No0000183]Parallel Programming with .NET-How PLINQ processes an IEnumerable<T> on multiple cores

As Ed Essey explained in Partitioning in PLINQ, partitioning is an important step in PLINQ execution. Partitioning splits up a single input sequence into multiple sequences that can be processed in parallel. This post further explains chunk partition…

[No0000182]Parallel Programming with .NET-Partitioning in PLINQ

Every PLINQ query that can be parallelized starts with the same step: partitioning. Some queries may even need to repartition in the middle. Partitioning is a fairly simple concept at the high level: PLINQ takes a lock on the input data source, bre…

Python并行（parallel）之谈

简介可以先看看并发Concurrent与并行Parallel的区别在谈并行前,头脑中总会浮出多线程.多进程.线程/进程同步.线程/进程通信等词语. 那为什么需要同步.通信,它们之间的作用是怎样的呢? 通信,稍微好理解,就是多线程/进程之间相互通话,比如我打电话呼叫你,我说什么,你答什么,或者我说,你只听.它着重于数据的传递同步,其实是相对于共享内存而言,比如,我们在同一时刻同一个地方修改了共享对象的数据,这样就会导致数据的篡改,得不到理想中的结果,这时就需要同步.它的基础是基于共享同一个对…
