The parallel program improvement on distributed - memory multicomputer 分布式存儲環(huán)境下并行程序的優(yōu)化
In multicomputer system , the efficient communication between computers is very important to improve the system ' s performance . recently , hypercubes multicomputers have been drawing considerable attention from many researchers 在多機系統(tǒng)中,處理器之間的高效通信對于提高系統(tǒng)的性能十分重要,于是,研究多機系統(tǒng)結(jié)構(gòu)上的路由技術(shù)成為高性能計算機系統(tǒng)應(yīng)用的實際需要。
Given the communication protocol , this paper presents a state machine model based on primary / secondary distributive multicomputer communication system program , analyzes the solving methods of five parameters to present the state machine , and discusses the basic trellis architecture of source codes 摘要在約定通信協(xié)議的情況下,本文給出主從分布式多機通信系統(tǒng)程序的狀態(tài)機模型,分析表征狀態(tài)機的5個參量的求解方法,討論源代碼實現(xiàn)的基本框架結(jié)構(gòu)。
With the development of vlsi and hardware technology , the size of the multicomputer systems is becoming larger , and the probability of processor failure also increases . with the rapid development of the information technology , people increase their need of network communication . wireless networking is one of the essential technologies to implement the mobile computer network 近年來超立方體結(jié)構(gòu)的多處理機系統(tǒng)得到廣泛應(yīng)用,隨著超大規(guī)模集成電路和硬件技術(shù)的發(fā)展,多處理機系統(tǒng)的規(guī)模也越來越大,系統(tǒng)中出現(xiàn)處理機故障或處理機間的鏈路故障的可能性也隨之增加,因此,如何建立一個可靠的多處理機系統(tǒng)越來越受到關(guān)注。
Sharing or full use of information or data is realized in dis . this article mainly discusses the application of dis through building a torpedo guidance and control distributed interactive simulation system ( tgcdiss ) . the research methods and contents can be described as follows : 1 ) how to assign multitask of tgcdiss to multicomputer is discussed 本文從分布式仿真技術(shù)的應(yīng)用研究角度出發(fā),對魚雷的導(dǎo)引控制規(guī)律及其運動過程進行了深入的研究,并利用visualc + + 6 . 0和opengl將文中所研究的內(nèi)容和方法進行了實現(xiàn)。
