A large scale virtual parallel system which is composed of a large number of computers on the Internet and executes parallel programs is called a metacomputing system or a global computing system. In this paper we first introduce the global computing research which has already been performed or is being performed now and then discuss important issues that should be considered when we design and implement global computing systems. Among these issues scheduling becomes one of the most important issues and we propose the structure for a scalable distributed scheduler system. The proposed scheduler system has the composite structure of a tree and a graph and the characteristic of being both efficient and easily controllable.
