Grid Technology in Higher Vocational and Technical Education Application Prospect4645

1、grid technology in higher vocational and technical education application prospect the emergence of the network has changed the way people use computers, while the emergence of internet, but also changed the way people use the network. now, we seem again to a new historic turning point. from the back

2、bone network to broadband access, from the language interface to the intelligent terminal devices, from e-commerce to enterprise information systems, from semiconductor chips to the server, people have done a lot of technological innovation. now, the whole industry is moving toward a new generation

3、of technology, known as the next-generation internet technologies - grid. the application and development of grid technology will push the global development of the internet to enhance the overall level. at present, the network technology has been widely used in education, higher vocational and tech

4、nical education is characterized by its vocational and technical application of network technology is making great efforts for the training is different from regular higher education, and application-oriented technology, expertise and play a significant role. grid technology as the next generation i

5、nternet technologies, and network technology will, as in higher vocational and technical education has played an important role in an unusual and widely application. 1, what is the grid as the grid is an emerging technology, the current concept of grid technology is not uniform. what is the grid? so

6、me people put the grid is defined as an extension of a supercomputer, and some definitions that the grid is a common computer. in ibms philosophy, the grid seems to be the internet as a computing platform. in academia, there were broken down according to application mode of calculation and data grid

7、, information grid, knowledge grid, as well as business applications, grid and so on. chinese academy of engineering and president of mr. li guojie dawn talked about, put simply, the grid is integrated into the entire internet, a giant super-computers, to achieve, such as computing resources, storag

8、e resources, data resources, information resources, knowledge resources, expert resources, all aspects of sharing. of course, we can also construct a regional grid, enterprises and institutions within the grid, local area network grid, and even families and individuals in the grid. we are familiar w

9、ith internet technology and web technology to realize the computer and web connectivity, while the grid will effectively and securely manage and share connected to the internet on a variety of resources and provide the necessary services. the current technology has not yet achieved a comprehensive l

10、evel of sharing of resources, but information transmission, so part of network technology rather than the grid. the new wave of the internet in real terms is, to a www (world wide web) sublimation of the grid (great global grid), which achieve the www to ggg change. second, the practical significanc

11、e grid as you know, all current institutions or individuals are not using a computer at work all the time, and these computers are there is a lot of idle resources, they are widely distributed in various places. mainframe, 40% of the time is idle, unix server, less than 10% of the time a real execut

12、ive tasks, almost all of the pc every day, 95% of the time did nothing. the use of grid technology, will not make full use of these resources are applied so as to enhance the function node computer network to make it as a large or giant computer work. as an integrated grid computing and resource env

13、ironment, to attract a variety of computing resources, to translate them into a readily available, reliable, standard and relatively economical computing power, its absorption of all types of computing resources, including computers, network communications capabilities, data, equipment operational c

14、apability and even a variety of people related resources. reference grid is put forward the concept of power grid, the grids ultimate purpose is to use grid computing users the ability to solve problems as easy as the use of electricity, users do not have to consider the services they have received

15、from what location, by what kind of computing facilities. in other words, to the end of the grid provided by the user is a universal computing power, and this ability is off the grid is difficult to achieve. in other words, the end-user access grid using ordinary computers, will be given a giant sup

16、ercomputer computing power. third, grid technology in vocational education in the application of prospect before the grid is also in-depth study into domestic and foreign scientists and scholars from their own point of view of grid technology research. in china, the chinese academy of sciences grid

17、computing group in the knowledge grid research work in the international counterparts in the leading ranks. i believe that in the near future, the grid will become a reality, grid applications will be the same as grid technology to all walks of life involved in various fields. vigorously develop voc

18、ational and technical education in todays grid will certainly be in higher vocational and technical education be widely applied. the prospects for this application do? reposted elsewhere in the paper for free download http:/ 1, the grid resources for full sharing of grid resources for full sharing,

19、which is grid in various application areas of common characteristics. computers will be organized into different locations of a virtual supercomputer, in which each computer involved in the calculation is a node, and the entire calculation is by all the nodes common completed, so that the limited re

20、sources available fully utilized. currently, network technology application in education can be broadly summarized as the following: distance education. people can not see the classroom, but at home you can accept the guidance of teachers, and to learn the relevant professional courses, the completi

21、on of the relevant professional teaching program. campus network. campus network for information sharing and information to achieve high-speed transmission. teachers and students through the campus network to share access to internet, from the internet, access to vast amounts of information; availab

22、le through campus network release information, and to collect student feedback on various subjects and to answer the difficult problems of students; extends the teachers and students with communication channels, increase the quality of teaching. all kinds of practical training network. such as: basi

23、c computer training rooms, network technology, training rooms, information systems, training rooms, the financial accounting training rooms, etc., various types of training rooms using network technology to achieve some of the software and hardware resources, share and communicate with each other. h

24、owever, in these applications, computer resources have not been fully utilized. the campus computer network, even all the boot, at some point, there are a large number of computers in a standby state. in the work of a computer is just an isolated use of the local computers processing power. in deali

25、ng with the work of a larger process is complete, our feeling is that your computer directly to the speed is too slow. if the full sharing of resources, a person using the computer will make full use of the nodes in the grid idle resources to enable them to use a substantial increase in computer pow

26、er, it would be a new experience. in the grid, the use of educational resources is relatively full. in distance education, there will be possible to develop a more comprehensive courseware, network speed bottleneck real solution to the problem, so that the computer in the grid, do everything accordi

27、ng to need (resources). 2, higher vocational and technical education in the grid application prospects because vocational and technical education is different from general education, which, in the application of grid technology will also be different from general education. in particular, higher voc

28、ational and technical education to foster applied talents as the goal, thus the application of grid technology, the more its own characteristics. can make use of grid technology, the formation of practical training simulation environment. vocational education should cultivate the high-level technolo

29、gy personnel in order to be able to hands-on as the goal. in many culture professionals, and now the majority of physical training in the field is used. such as cars driving, fly drive, chemical production manipulation. however, the high cost of the field kind of training, and some jobs are difficul

30、t to in-kind practical training. if the large-scale use of this method is also a waste of social resources. if the formation of various types of practical training with the grid simulation environment will be an economical cost of education, an effective way to improve teaching quality. the use of g

31、rid technology to develop a courseware characteristics of higher vocational education. the courseware is now due to computer hardware and software constraints, characteristics of higher vocational education courseware to realize there are still considerable limitations (of course, designed coursewar

32、e level is a subjective limit). in the courseware production, if you want better results and better appeal, you have the appropriate number to use voice, photographs, three-dimensional animation effects, but the application of these effects, in the general development of the computer and run all is

33、a very difficult thing. in the grid, the grid due to the use of the other nodes in the computers idle resources, the speed of your computer will no longer be a problem, the remaining issue can only design courseware creativity and technology. grid itself will promote the development of higher vocational education. grid is an emerging technology that will be the same network technology as widely used. this application will create new jobs and tens of thousands of em
