并行处理系统中的共享资源互斥操作——锁控制技术的一种应用模型

并行处理系统中的如何解决共享资源冲突是系统结构设计的关键问题之一。传统上的共享资源互斥操作是通过单机操作系统分时模式实现多任务管理，但多模式操作系统的并行节点都具备对共享资源进行更新的权利。为防止共享资源访问冲突，高级锁机制在并行处理中就是解决共享资源冲突的一个关键技术。从系统结构方面对构成互斥操作的锁控制算法进行了分析，并基于NODS设计规划提出了一种切实可行的互斥操作模型，以解决并行处理系统中的共享资源冲突问题。

A Shared Resource Mutually Exclusive Operation in Parallel Processing System--The Application Model of Lock Control Thechnology

It is one of the pivotal technology that mutually exclusive operation is in the system structural design of the parallel processing to solve resource conflict.Traditionally,the sharer resource mutually exclusive operation is managed by single-computer operation system time-sharing mode for multitask condition,but all of parallel nodes possess renovate right in multi-mode OS,so high-grade lock mechanism is a pivotal technology to solve share resource confilict in parallel process to prevent share resource accessing conflict.This article describes lock control arithmetic of mutually exclusive operation from system structure and puts forward mutually exclusive operation model based on NODS.
