Recently, the distributed computer system, which consists of a collection of autonomous workstations(nodes)connected by a local area communication network, is commonly used. In order to control such a system efficiently, it is necessary to apply a load distributing technique to assign the newly created process to a suitable node. Several researches about load distribution have been reported. However, the load distributing methods proposed before have the following problems : 1. They are concerned about only CPU load, or they pay slight attention to other resources such as memory, disk, network and so on ; 2. 0n assigning a new process, the characteristics of the process are not focused on ; 3. The influence, which the newly assigned process causes to other processes on the same node, is not taken into account. In order to solve the above problems, we compose a model of distributed computer system and propose a process assignment method based on this model. Our model takes not only the CPU resource but also the memory resource into account, and can predict the system behavior successfully.
