This problem is about a war game between two countries. To protect a base, your country built a defense system called “Tactical Multiple Defense System” (TMD system in short). There are two weapons in the TMD system: Line gun and Circle gun. The Line…

An improved memory model and implementation is disclosed. The memory model includes a Total Store Ordering (TSO) and Partial Store Ordering (PSO) memory model to provide a partial order for the memory operations which are issued by multiple processor…

BACKGROUND Memory allocation systems assign blocks of memory on request. A memory allocation system employs an allocator to receive relatively large blocks of memory from an operating system and allocate that memory to satisfy memory requests. Upon r…

1 Protection Profile Introduction   This document defines the security functionality expected to be provided by a general-purpose operating system capable of operating in a networked environment. It also provides a set of assurance components that de…

The present invention allocates resources in a multi-operating system computing system, thereby avoiding bottlenecks and other degradations that result from competition for limited resources. In one embodiment, a computer system includes resources an…

UNIX标准及实现 引言     在UNIX编程环境和C程序设计语言的标准化方面已经做了很多工作.虽然UNIX应用程序在不同的UNIX操作系统版本之间进行移植相当容易,但是20世纪80年代UNIX版本的剧增以及它们之间差别的扩大,导致很多大用户(例如美国政府)呼吁对其进行标堆化.     本章首先将介绍过去20年来进行的各种标准化工作,然后讨论这些UNIX编程标准对本书所列举的各种UNIX操作系统实现的影响.所有标准化工作的一个重要部分是对每种实现必须定义的各种限制进行说明,所以我们将说明这些限…

概述 MQ全称为Message Queue, 消息队列(MQ)是一种应用程序对应用程序的通信方法.RabbitMQ是一个在AMQP基础上完整的,可复用的企业消息系统.他遵循Mozilla Public License开源协议.AMQP(高级消息队列协议) 是一个异步消息传递所使用的应用层协议规范,作为线路层协议,而不是API(例如JMS),AMQP 客户端能够无视消息的来源任意发送和接受信息.AMQP的原始用途只是为金融界提供一个可以彼此协作的消息协议,而现在的目标则是为通用消息队列架构提供通用…
