unstructured file

4) This thesis presents two PC-based streamline visualization methods for large unstructured grids: Memory-Mapped File Method ( MMFM) and MultiThread Out-of-core Method ( MTOM).

4）针对大规模非结构网格，提出了两种基于PC的流线可视化方法：内存映像文件方法（MMFM）和多线程out-of-core方法（MTOM）。

This strategy uses Chord protocol as group management Protocol in unstructured P2P networks; all replica nodes of the same file form a Chord ring. An update propagation tree is gradually built by continuous dividing the node space in Chord ring.

该策略在无结构P2P网络中使用Chord协议作为组管理协议，同一文件的所有副本所在节点构成一个Chord环，通过不断分割Chord环上副本节点的空间区域，逐渐构建一棵更新传播树。
