The grid is rapidly developed with Internet technology, initially specializing in a new type of computing model for complex scientific computing applications. This calculation mode is to integrate the entire network into a huge supercomputer. We can understand the grid like this. The grid is a series of distributed computing resources provided by a LAN or a wide area network, while the terminal user or application seems to be a large virtual computer. This concept is to create virtual dynamic organizations by achieving security, coordinated resource sharing between individuals, organizations and resources. Grid computing is a method of distributed operations not only including location, but also covers organization, hardware, and software to provide unlimited capabilities, allowing everyone to connect to the grid to cooperate and access information. Typical application of grid 1 Scientific research (E-Science) 2 E-Business) 3 E-Entertainment 5 E-EDUCATION Net Key Technology 1 is the research and implementation of grid software technology, and is the main research object in grid system software; 2 requires an open architecture, standards and protocols to form information acquisition, transmission, access, sharing, and handling single Open information processing infrastructure platform requires the management and collaborative work issues of virtual organizations; 3 to solve the availability and developmentability of the grid, system security technology. Trend of grid 1 Walking the standard route; 2 multi-technical integration; 3 build a grid operating system; 4 forming information integrated service providers; 5 service grid is an important product direction. The purpose of the advantages and disadvantages of the grid is to provide unlimited computing power by any computer, which can access the vast smoke. Such an environment will enable companies to solve problems that have been difficult to handle, using their systems to meet their requirements and reduce their computer resources with total cost of ownership. The main purpose of grid calculation is to design a system that provides the following functions: 1 Increase or utilize all the efficiency and utilization rates in all computing resources in the development, meet the needs of end users, and can solve the previous due to calculation, data or storage resources. The shortage of shortage is unable to solve. 2 Establish a virtual organization to cooperate public problems by allowing them to share applications and data. 3 Integrate computing capacity, storage, and other resources, enabling a huge problem that requires a large amount of calculation resources. 4 can reduce the total cost of calculation by sharing, effective optimization and overall management of these resources. Now, grid computing is mainly used by universities and research laboratories for high performance calculation projects. These projects require huge computing power, or need to access a lot of data.
