The invention discloses a system for inviting multi-grid platform generally, comprising a task manager, a storage manager, a registration manager and a safety manager. The invention realizes the general task visit of the grid programming environment and grid public support platform of China educational science research and completely improves the integration and utilization rate of grid resource. The registration manager manages each target system, maintains the topology structure of grid, allows the grid node to register to registration service and coordinates the load balance of each node. The storage manager provides uniform grid data storage management, abstracts basic data operations such as storage data and provides a uniform, simple and complete storage space service for users. The task manager executes the task submitted by users, firstly obtaining input data from user data space, then generating performing script designated platform according to the submitting task, and the result is returned to the user space after performing script. The safety manager safely detects and controls the service utilization.
