碩士 === 國立臺灣大學 === 造船工程學系 === 82 === DCS(Distributed Conputing System) plays an important role in modern computer applications. Intergrating several low-cost machines into a network and processing jobs parallelly, we can perform a higher computing power than single machine. It can also support a complicated control and measurement system for real time purpose. However studies of DCS are almost concen- trated on workstation networks. In Taiwan, the applications enviroment of personal computers are much better than work- stations, thus it is worth to study the DCS in personal computers systems. A dynamic network for personal computers is adoptedin this paper. For the dynamic linking networks, we developed a Bi-port Ram Module(BPRM) and a Multi-Bus Card (MBC). One personal computer could connect to 4 other personal computers through the BPRM and MBC. In case study, three personal computers are connected together as a network for DCS. We made two tests for for ditributed computing on this network. One is a computing intensive test, it gets 2.18 times speed faster than the fastest computer in system . Another is a test for searching database, it makes 2.67 times speed. In this paper, the expressions of a task are divided into three parts: CPU,IO, and Network expressions, one can use such classi- fication to predict the processing time of each computer of net- work and the efficiency of the whole system.
