“The grid computation” is one of most popular technical terminology which this century propagandizes widely. In each kind of conference, one kind of challenge is nearly all products or the manufacturer all declared they are “the attention grid”, “the grid realization” or “comply with the grid”. All main computer manufacturer all signs a treaty (most also more than once) complied with already appears the grid computation and the Web service standard with the support. Many volume yi vast textbooks often the crown uses the grid the title. But one kind follows approaches which hysteria to propagandize the new technical not mature reality causes some technical personnel to any “the grid” the formulation to feel was sick of.

Creates one of chaotic primary causes is about the grid definition. I have heard the related grid definition, some meaningless, if “any pair does not share the public file system CPU”), some excessively exaggeration and are not clear about, if “the grid enables the world to become your computer”. Some definitions stresses on interoperability as well as has the safeguard service rank using the level. Also had some definitions to emphasize the space and the data management. Many definitions stresses in the situation which restrains is not used in majority user's CPU the idle CPU might. For example, Wisconsin University Madison Branch school is outside the exploration ball the wisdom distributed computing project, as well as Condor software developmental item which connects PC and the supercomputer.

What grid computation already the definition which widely accepted is come from Ian Foster the white paper which published in 2002 "the grid was? " Foster and his collaborator Carl Kesselman acted according to a time academic seminar the paper to assemble a main subject are "the grid: New computation construction blueprint" book. Below Foster gives in the book defines:

•Grid coordination not common control influence resources;
•The grid uses the standardization, the opening as well as the general agreement and the connection;
•The grid provides the ultra first-class grade of service.

In brief, the grid computation is the foundation surmounts the organization and the platform boundary scale very greatly moreover the extremely suitable system. Foster pointed out soon, non-operation and benefit computation thought by no means new thing. As early as in the 20th century 60's, many authors must use the state-level on the prediction the computation construction and the pronunciation communications system, the highway transportation as well as the electric power distribution system existing system competition. Obviously, founds this kind of kind of construction character's realization needs to spend more time compared to its forecast.

And is willing to let their work move the scientist who lets it keep the grid very few in the grid.

Global grid forum (GGF) is the standardized research entity which the 90's last stages form. GGF formulated some to have the vital significance document in view of the realization grid computation aspects, including data, security, performance as well as dispatcher. Globus is realized by the GGF acceptance according to the original code public principle each kind of standard tool bag. Certain commercialized software sells the host always to use each kind of GGF standard in theirs product. About submits the work to the long-distance aggregated computer, has other standard: Distributional resources manager application program interface (DRMAA).

Local thought

Affects the GGF standard widespread acceptance a barrier has such actual situation: The Globus tool bag software is the scale is very big not not easily, to use moreover the not very firm software. Its 2.4 edition have been used by many projects certain years, compares it is can realize the grid service firmest tool. Even if uses Globus 2.4 success conformity quantity not many resources in the user nobody to say it is simple or the non-pain.

In 2003, the alliance which was composed by the field and the academic expert can the web service and the grid unifies as soon as in together set of standards achieved express best wishes the opinion. They believed, the grid computation can in the web service foundation by the best way construction. This thought can realize in Globus tool bag 3rd edition. So long as the realization grid service core software installment has the difficulty, very is difficult to produce lets the aggregated superintendent or the IT administrative personnel uses this ship the power. The grid has not had the benefit to the local subscriber or the system owner which propagandizes. Why will need to spend how many month of work to install and disposes the software later to be able to cause exterior not to be able to receive the bill the user to profit? Hypes the grid from the propaganda turns the reality the key is, must emphasize such fact, the design has the system which the elasticity and operates mutually to be supposed to enable the local subscriber to obtain the benefit. From looked for a long time that, such system should maintain the system which other may substitute simple and is much more inexpensive than. Installs any system the first several superintendents (as well as their user) should undertake the main expenses which creates by the first edition software flaw as well as the fault time.

For all this, the company finally may from the flexibility which increases day by day and expandable obtains benefits. Therefore some big pharmaceutical company already started to request their system to have can have the good result the interoperability.

Whether trusts is uses the grid technology the main hindrance. The owner and the administrative personnel must be able reasonably and use safely to their resources have the confidence. Although indulges in unbridled propaganda “works according to ability, each according to his need” the ideal boundary about in the grid article, once but meets the company the firewall, or budgets in the company with the rational hearing committee on this kind of altruism philosophy can encounter the denial. Even if the construction grid has many resounding and the practical reason, so long as in the grid partner establishment to its trust, construction grid all technologies diligently has not been doomed to have to be defeated. The user must have to have the trust, they must believe firmly the grid computed result are reliable moreover are may reappear. I meet and in the scientist is willing to let their work move in the grid lets it keep the grid very few.

 In order to let the grid computation transit from one kind of pledge technology to the solid information infrastructure, and needs to develop for the user some can meet the actual needs the application procedure to have the understanding truly to the process. Aggregated is called merely one the grid, or is called an image editing software package “the attention grid”, simply not impossible to cause any stimulation regarding our these senior users. I the reason that to hoped “installment grid” the customer retains according to several hot key patiences, in order to look at such facts merely, because basic does not have the explicit customer or the impetus makes this kind of diligently actual demand, foundation any system in “the world, you is good” such initial period to be able to announce the die young.

Had some companies and the research team truly has completed the unusual work using the opening agreement to the distribution widespread type different heterogeneous type system. These groups have the general character face the difficult global duty, moreover the timetable is very short. Is same with any other newborn information infrastructure, must by take the lead the human who and constructs the firm system to establish the firm standard.
