Parallel I/O and Columnar Storage We begin with a high level overview of the system while follow up posts will discuss specific components in more detail. The target audience are software and systems engineers with an interest in databases and distri…

A novel massively parallel supercomputer of hundreds of teraOPS-scale includes node architectures based upon System-On-a-Chip technology, i.e., each processing node comprises a single Application Specific Integrated Circuit (ASIC). Within each ASIC n…

A Pattern Language for Parallel Application Programming Berna L. Massingill, Timothy G. Mattson, Beverly A. Sanders Abstract Parallel computing has failed to attract significant numbers of programmers outside the specialized world of supercomputing.…

System.Threading.Tasks.Parallel类提供了Parallel.Invoke,Parallel.For,Parallel.ForEach这三个静态方法. 1 Parallel.Invoke 尽可能并行执行所提供的每个操作,除非用户取消了操作. 方法: 1)public static void Invoke(params Action[] actions); 2)public static void Invoke(ParallelOptions parallelOption…

1.并发与并行的区别 并发: 一个时间段内有几个程序都处于已启动到运行完毕之间,且这几个程序都是在同一个处理机上运行.但在任一个时刻点只有一个程序在处理机上运行 并行: 在同一个时刻,多核处理多个任务.把工作拆分,同时在多核CPU上执行 2.parallelStream及parallel 在C#中,有Parallel类提供并行编程,同样在Java 8中针对Stream,Java 8也提供了parallelStream并行化编程. 2.1C#的Parallel static void Main(s…

关于Parallel我也不细说了,一则微软封装的很好用,二来介绍这个的遍地都是. 我要说的是,要想成为一个优秀的标题党,一定要把重点放到别的地方,为了节省大家阅读时间,我先把结论说了,然后再慢慢从头说,愿意往下看的可以看看因果,不愿意看的,也算咱给大家提个醒吧. 结论就是,大家在做单元测试用例的时候一定要用心,这篇随笔是要检讨并警醒下自己并与大家共勉. 据一些我不记得名字的国外权威专家,据说是测试大师级人物研究,测试用例的出现的错误并不比被测试的代码少,我相信大多数人会和我类似,在写代码的时候小…

坏味道--平行继承体系(Parallel Inheritance Hierarchies) 平行继承体系(Parallel Inheritance Hierarchies) 其实是 霰弹式修改(Shotgun Surgery) 的特殊情况. 特征 每当你为某个类添加一个子类,必须同时为另一个类相应添加一个子类.这种情况的典型特征是:某个继承体系的类名前缀或类名后缀完全相同. 问题原因 起初的继承体系很小,随着不断添加新类,继承体系越来越大,也越来越难修改. 解决方法 一般策略是:让一个继承体系的…
