實(shí)用操作系統(tǒng)概念

前言

20世紀(jì)末，以計(jì)算機(jī)和通信技術(shù)為代表的信息科學(xué)和技術(shù)，對世界的經(jīng)濟(jì)、軍事、科技、教育、文化、衛(wèi)生等方面的發(fā)展產(chǎn)生了深刻的影響，由此而興起的信息產(chǎn)業(yè)已經(jīng)成為世界經(jīng)濟(jì)發(fā)展的支柱。進(jìn)入2l世紀(jì)，各國為了加快本國的信息產(chǎn)業(yè)，加大了資金投入和政策扶持。為了加快我國信息產(chǎn)業(yè)的進(jìn)程，在我國《國民經(jīng)濟(jì)和社會發(fā)展第十個五年計(jì)劃綱要》中，明確提出“以信息化帶動工業(yè)化，發(fā)揮后發(fā)優(yōu)勢，實(shí)現(xiàn)社會生產(chǎn)力的跨越式發(fā)展?！毙畔a(chǎn)業(yè)的國際競爭將日趨激烈。在我國加入WT0后，我國信息產(chǎn)業(yè)將面臨國外競爭對手的嚴(yán)峻挑戰(zhàn)。競爭成敗最終將取決于信息科學(xué)和技術(shù)人才的多少與優(yōu)劣。在20世紀(jì)末，我國信息產(chǎn)業(yè)雖然得到迅猛發(fā)展，但與國際先進(jìn)國家相比，差距還很大。為了趕上并超過國際先進(jìn)水平，我國必須加快信息技術(shù)人才的培養(yǎng)，特別要培養(yǎng)一大批具有國際競爭能力的高水平的信息技術(shù)人才，促進(jìn)我國信息產(chǎn)業(yè)和國家信息化水平的全面提高。為此，教育部高等教育司根據(jù)教育部呂福源副部長的意見，在長期重視推動高等學(xué)校信息科學(xué)和技術(shù)的教學(xué)的基礎(chǔ)上，將實(shí)施超前發(fā)展戰(zhàn)略，采取一些重要舉措，加快推動高等學(xué)校的信息科學(xué)和技術(shù)等相關(guān)專業(yè)的教學(xué)工作。在大力宣傳、推薦我國專家編著的面向21世紀(jì)和“九五”重點(diǎn)的信息科學(xué)和技術(shù)課程教材的基礎(chǔ)上，在有條件的高等學(xué)校的某些信息科學(xué)和技術(shù)課程中推動使用國外優(yōu)秀教材的影印版進(jìn)行英語或雙語教學(xué)，以縮短我國在計(jì)算機(jī)教學(xué)上與國際先進(jìn)水平的差距，同時(shí)也有助于強(qiáng)化我國大學(xué)生的英語水平。為了達(dá)到上述目的，在分析一些出版社已影印相關(guān)教材，一些學(xué)校已試用影印教材進(jìn)行教學(xué)的基礎(chǔ)上，教育部高等教育司組織并委托高等教育出版社開展國外優(yōu)秀信息科學(xué)和技術(shù)優(yōu)秀教材及其教學(xué)輔助材料的弓！進(jìn)研究與影印出版的試點(diǎn)工作。為推動用影印版教材進(jìn)行教學(xué)創(chuàng)造條件。

章節(jié)摘錄

插圖：Symmetric multiprocessing（SMP）means that all processors are peers；thereis no master-slave relationship between processors.Each processor concur-rently runs a copy of the operating system.Figure 1.5 illustrates a typical SMParchitecture.An example of the SMP system is Encore's version of UNIX forthe Multimax computer.This computer can be configured such that it employsdozens of processors.all runnhag copies of UNIX.The benefit of this model isthat many processes can run simultaneouslyn（N processes Can run if there areN CPUs）-without causing a significant deterioration of performance.How.ever, we must carefully control I/O to ensure that the data reach the appropriateprocessor.Also.since the CPUs are separate. one may be sitting idle while another is overloaded. resulting in inefficiencies. These inefficiencies can be avoided if the processors share certain data structures. A multiprocessor system of this florin will allow processes and resources-such as memory-to be shared dynamically among the various processors, and can lower the variance among the processors. Such a system must be written careful as we shall seeing Chapter 7。Virtually all modem operating systems including Windows NT,Solaris,Digital UNIX.OS/2.and Linux-now provide support for SMPThe difference between symmetric and asymmetric multiprocessing may bathe result of either hardware or software. Special hardware call differentiate the multiple processors, or the software can be written to allow only one master and multiple slaves. For instance, Sun's operating system SunOS Version 4 provides asymmetric multiprocessing, whereas Version 5（Solaris 2）is symmetric on the same hardware.As microprocessors become less expensive and more powerful additional operating-system hmctiOIlS are off-loaded to slave processors. or back-ends. For example, it is fairly easy to add a microprocessor with its own memory to manage a disk system. The microprocessor could receive a sequence of requests from the main CPU and implement its own disk queue and schedulingalgorithm.This arrangement relieves the main CPU of the overhead of diskscheduling.PCs contain a microprocessor in the keyboard to convert the keystrokes into codes to be sent to the CPU.In fact, this use of microprocessors has become SO common that it is no longer considered multiprocessing.
