| 摘 要： | 元计算系统的节点间具有多方面的异构性，当数据在这些点间传输时，会发生理解或判断上的歧义性，为了实现数据和文件在异构节点间传输的一致性，分析了校园网络内的几种典型计算机系统的数据类型及其存储格式，研究了不同数据格式之间的转换算法和远程文件传输机制，格式转换算法使用元数据信息作为数据信包转换和解压缩的依据。

| Abstract: | A metacomputing system contains heterogeneity in many aspects. When transferring data between these nodes, the same information is possibly regarded as different meanings. For consistency of data between heterogeneous nodes, the data types and their storage formats of some typical hosts are analyzed in detail, the algorithm for converting two heterogeneous data formats is presented, and the method for transferring files between nodes is also implemented in this article. The meta data information of each host is considered as the key information of the algorithm implementation. |
