Both grid mapping and grid computing are effective methods to describe, analyze and virtualize regional geographic phenomena and their applications to the analysis of the spatial pattern are quite promising.
On this background, the National High Technology Research and Development Program of China (863 program) proposes a novel concept, i.e. Spatial information Grid (SIG), aiming at integrating some new techniques, including grid computing, OpenGIS specifications and Web services, to solve the existing application problems and satisfy multi-layer application requirements.
为此,“863”信息获取与处理技术主题提出空间信息栅格(Spatial Information Grid,SIG)这一创新性的概念,旨在吸纳Grid、OpenGIS、Web Services等新技术的特点,着重在空间信息共享与互操作、空间信息应用集成、高性能空间信息分析处理等方面解决当前空间信息应用中的各种问题,满足多层次的空间信息应用需求。
Shortly after the emergence of Enterprise Resources Planning (ERP), computer technology come to an era of grid computing, Internet/Intranet, the internationalization of manufacturing trends and promotion of manufacturing information technology.
The conception and the importance of the grid computing are given, and the computational market/economy grid model is introduced. Grid resource management and scheduling model are abstracted and the hierarchical thought of resource management and scheduling are put forward in the grid computing.
A new model of computer with active memory (CAM) is proposed, where the memory cells are equipped with traditional read/write operations as well as new execution operations. This CAM model extends the traditional RAM model, and can be used to study architectural mechanisms and algorithms design and analysis of emerging computing paradigms, such as system-on-chip (SoC), reconfigurable computing, parallel computing, grid computing, and web service. For grid computing,...
The discovery, characterization, and monitoring of resources, services, and computations can be challenging due to the considerable diversity, large numbers, dynamic behavior, and geographical distribution of the entities in grid computing systems. Hence, resource information services are a vital part of any grid software. A grid resource information model is designed in object-oriented way, and directory service is used to implement resource information service of grid system ...
