Abstract

The invention discloses a memory database-based simulation grid node quick migration method, which comprises the steps of utilizing a memory database to establish a complete state mirror image set of various simulation nodes in a real-time manner, carrying out distributed collection and management on state mirror images, completing fault simulation node detection, pause and running control of the simulation process, fault node or process migration, fault node state mirror image injection and continuous running control of the simulation process through simulation running management, state monitoring, node migration and recovery and other mechanisms in a simulation grid, and further realize the quick migration of fault nodes in the simulation grid.

Description

technical field [0001] The invention relates to a fast migration method for simulation grid nodes based on a memory database, in particular to a method for quickly and dynamically migrating faulty nodes in a simulation grid to other nodes based on a memory database, and belongs to the technical field of distributed interactive simulation. Background technique [0002] Distributed simulation based on HLA (High Level Architecture) has been widely used in military, scientific research, engineering, business, etc., and is playing an increasingly important role. In the face of the current large-scale development of distributed simulation and the need to use geographically distributed computing resources and data resources, the traditional HLA-based distributed simulation has certain limitations. The emerging technology of simulation grid Then came into being, it uses the advantages of grid computing technology to transplant the traditional distributed simulation to the grid envir...
