【摘要】 数据密集型计算的飞速发展以及数据量的迅速膨胀对信息处理能力的要求越来越高,在这种情况下,数据网格应运而生。它可以满足分布异构的海量信息高效处理的应用需求,广泛应用到地球科学、高能物理学、医学、协同制造与设计等领域,数字人即是其中之一。将数字人与远程教育相结合,建立一个局域网环境下的远程教育实验系统,借助于数字人模型,可实现授课、实习、讨论、检查与辅导等多种功能。其中基于网格思想的海量数据管理系统,为数字人海量数据集提供了高效、安全、透明的数据存取与访问机制。最后通过一个运行实例显示了本系统的正确性与可行性更多还原

【Abstract】 The booming of data intensive computing and the exploration of amounts of data challenge the current information processing ways. Under this condition, data grid emerges as a solution to the problems confronted by processing of mass distributed and heterogeneous data. It has wide applications in the areas like earth sciences, high-energy physics, medicine, cooperated design, etc., with digital human is one of which. In this paper, a distance education system of digital human in local network is introduced, which contains functions including teaching, discussing, practicing, tutoring. The data grid based mass data management system provides an efficient, safe and transparent data accessing for large datasets of digital human. At last, an example proves the feasibility and validity of our solution.更多还原
