Limited bandwidth and high delay make application very difficult to archive good performance. In this dissertation, we have developed optimal collective communication library CAMPI for campus area based on MPI collective communication operation and have taken hierarchical network structure into account. In CAMPI, the number of clusters in system must be specified. We also must show which process belongs to which cluster.

本文充分考虑到网络的等级体系结构，针对不同的网络情况，在MPI集合通信的基础上提出了基于校园网系统的优化集合通信操作库CAMPI(campus area message passing interface)，它建立在MPI操作库之上，在CAMPI操作库中需要指定整个系统中有多少个机群，哪个进程属于哪个机群，CAMPI操作库在MPI之上实现，系统中必须首先安装MPI实现，例如最常用的MPICH。

The study contains five parts excluding introduction. First, it reviews the literature. Secondly, it analyzes the organization of university-bureaucracy, collegium, political system, symbolic system and cybernetic system. Thirdly, it analyzes what is the visional president. Fourthly, we think about the dilemma- doing the right things and doing the things right, educational idea and the practice of policies, changing the organizational culture and developing step by step, administrative men and economic men.
