Recently, grid computing, which exploits extra computing resources, has attracted great attention. In grid computing environment, generally, by using several clients and calculating different equations against the large data generated by a server, the computation time is reduced. However, in the case where the number of clients is large, the system load becomes high and the computation time can become long. In this paper, we propose a delivering method to reduce the computation time using broadcasting delivery. In broadcasting delivery, the server broadcasts the data to many clients concurrently. Accordingly, the system load does not change even if the number of clients increases. Although clients have to wait until their desired data are broadcast, our evaluations show that we can reduce the computation time by dividing the data into only two segments.
