Abstract: Disclosed is a grid computing control method for testing the application program capacity of a server and a method for providing a service based on the same. The grid computing control method includes the steps of providing a number of user clients with a capacity measurement program by a capacity measurement server; selecting user clients capable of capacity measurement from the user clients, the capacity measurement program having been installed in the user clients, by the capacity measurement server; transmitting a capacity measurement script to the selected user clients by the capacity measurement server; executing the capacity measurement script so as to create capacity measurement data by the selected user clients; transmitting the created capacity measurement data to the capacity measurement server by the selected user clients; and collecting the transmitted capacity measurement data and composing a capacity measurement result report by the capacity measurement server.

Abstract: Disclosed is a grid computing system for testing the application program capacity of a server. The system includes an application server having an application program installed therein; a number of user clients having a capacity measurement program installed therein, the user clients applying a load, which contains a scenario, to the application program so as to create capacity measurement data regarding the application server; and a capacity measurement server for distributing a capacity measurement program to the user clients so as to transmit a load command, the capacity measurement server collecting the capacity measurement data created by the user clients and analyzing the capacity measurement data. The system creates loads as requests expected from actual users and uses them for the test so as to guarantee the stability of a developed system by anticipating problems which are likely to occur when the system is operated.
