26. What is the relationship between grids and CSCWs CSCW can define a group of geographical dispersed by means of computer and its network technology, coordinating and collaboration to complete a task. Grid promotes this working mode.
27. The independent computing of the grid is "independent computing" is the idea of "autonomous computing" is the increasingly complex IT system management of background, automation, and intelligence. Transform heterogeneous network into true sense Harmonious autonomous digital nervous system. The grid itself is a self-computing
28. What is a grid architecture
The grid architecture is a technical description of how to build a grid. It gives the basic components and functions of the grid, describes the relationships of each component of the grid and their integration methods or methods, portraying mechanisms that support grid effective operation.
29. The main structure of the grid has those architectures, what is the current development status. The grid architecture model proposed by the US Globus project adopts local service layer, core service layer, high-level service and tool layer, and a layer of four-layer structure. On this basis, the University of Argonne, University of Chicago, University of Chicago, and IBM, jointly proposed Open Grid Services Architecture, OGSA. OGSA uses a fiber layer, a contact layer, a resource layer, a collaborative layer, and a layer of five-layer structure.
30. The origin of the grid is what "Grid" (grid) is from the Power Grid. The current demand for calculation is continuously growing. High-speed network, function and performance is more powerful, large-scale computing system, high-performance storage system, and advanced data analysis software to solve the problem of calculation in business areas and scientific fields. But using these new capabilities means unprecedented challenges brought about by increasing workload requirements. When an organization is working hard to maintain competitiveness, they face many unprecedented challenges: reduce computing costs, increase computational throughput, and speed up the response to the market, improve production service quality and product innovation are very important. An organization's investment in hardware needs to be careful, and you must find a way to use available resources to complete more work. Although the demand for calculation is very large, many existing systems are not fully utilized. Some of these individual servers may be full of load, but most systems are not full-load work, which is not used in many computing cycles, and in fact these computing cycles can be used to meet growing computational resource requirements. The grid calculation allows organizations to more efficiently and flexibly with their distributed computing resources, from existing systems to help organizations gain competitive advantage.
