Abstract

The invention relates to an inverted-sequence model dispatching method of a distributed simulation system and belongs to the technical field of complicated system simulation. The distributed simulation system comprises a client-side, a master control engine and a computing mode. The inverted-sequence model dispatching method of the distributed simulation system comprises the steps that 1, simulation operation is initialized, namely a simulation task is sent to the master control engine and model distribution is completed; 2, the client-side sends a dispatching instruction to the master control engine, the master control engine parses a control instruction and performs model dispatching calculation, and a driving instruction is sent to the node where a model is located; 3, the computing mode receives the driving instruction to drive the model to operate and update output data; 4, the master control engine receives result data and calculates a downstream model set; 5, the master control engine judges whether the downstream model set obtained in the step 4 is empty or not, the step 3 is repeated or the method is completed. By the adoption of the dispatching method, the model operating efficiency is improved, the load of the master control engine is reduced, the time consumption for model dispatching is shortened, and the method has good universality.

Description

technical field [0001] The invention relates to a method for dispatching reverse order models of a distributed simulation system, belonging to the technical field of complex system simulation. Background technique [0002] With the continuous development of computer technology, the modern simulation environment is becoming more and more complex, more and more disciplines are involved, and the simulation scale is getting larger and larger. Single-machine and single-platform simulation cannot meet the needs of modern system simulation. In the 1980s, In the early 1990s, the concept of distributed simulation came into being. Distributed simulation refers to the use of coordinated structures, standards, protocols and databases to interconnect simulation devices scattered in various places through a wide area network or local area network to form a comprehensive simulation environment that can participate. [0003] In a distributed simulation environment, the simulation objects (...
