Embodiment Construction

[0023] The invention discloses a fault-tolerant method based on a high-performance simulation cloud. The method takes a high-performance simulation computer as a carrier, quickly and reliably identifies errors after a simulation error occurs during the simulation operation process, and migrates and restores the model, so that The entire simulation system recovers to the previous state recording point of failure, and continues the simulation operation. The steps of the method include

[0024] Simulation Error Classification Based on High Performance Simulation Computer

[0025] In the high-efficiency simulation of complex systems, in order to greatly shorten the simulation cycle, high-performance computers are used as hardware carriers for current simulation operations. Under the framework of the HLA high-level architecture, simulation tasks, simulation federations, and simulation objects will be allocated to different parts of the high-performance computer, and simulation mode...

Abstract

The invention discloses a fault-tolerant method based on a high-performance simulation cloud. The method includes the steps that the fault-tolerant type is determined by the characteristics of a computer according to simulation; all simulation members are added into a simulation system, and meanwhile a shared data area is established to record the simulation process; whether all the simulation members operate normally or not is judged through heartbeat detection, if operation is normal, the shared data area is used for recording and storing current data, and if operation is abnormal, the entire simulation system is returned to a previous recorded detection point; the fault-tolerant type of the abnormal condition is judged, a simulation model is redeployed, and after the abnormal simulation members are subjected to off-line error correction independently, the abnormal simulation members and other normal simulation members recover the simulation operation together. By the adoption of the fault-tolerant method, the state before errors can be recovered quickly through self-stored interaction data, operation of the simulation system is recovered again, reloading operation is not needed by the simulation system, and the simulation error probability in the process of operation again is avoided.

Description

technical field [0001] The invention relates to the field of computers, in particular to a fault-tolerant method based on high-efficiency simulation cloud. Background technique [0002] The high-efficiency simulation cloud based on the HLA simulation architecture is a high-performance simulation computer hardware that utilizes the network and specially customized, and the simulation complies with the HLA high-level architecture standard, and organizes various simulation software on demand according to the simulation needs of simulation users and a new emulation mode that provides high-performance emulation compute nodes. The goal of the high-performance simulation cloud is to build a simulation environment on demand for high-end simulation users and massive simulation users. The simulation environment required by each simulation user is different, such as the number of simulation nodes, the type of simulation software, etc., so the simulation support environment can be based...
