- Abstract
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.
