Embodiment 1

[0062] This embodiment will further elaborate on the "targeted operation of models that affect input parameters" mentioned in "a sequential model scheduling method for a distributed simulation system" of the present invention.

[0063] figure 1 The model data relationship diagram of this method contains 5 models, where the output of model 1 and model 2 is passed to model 3, and the output of model 3 is passed to model 4 and model 5, that is, the downstream models of model 1 and model 2 are Model 3, the downstream models of Model 3 are Model 4 and Model 5.

[0064] Depend on figure 1 It can be seen that it is necessary to pay attention to the impact of the operation of model 1 on the downstream model, then run model 1, model 3, and then run model 4 and model 5, but model 2 will not run; it is necessary to pay attention to the impact of model 3 on the downstream model impact, run model 3, then run model 4 and model 5, but model 1 and model 2 will not run.

Abstract

The invention discloses a sequential model scheduling method of a distributed simulation system, and belongs to the technical field of complex system simulation. The distributed simulation system comprises a client side, a master control engine and computational nodes. The sequential model scheduling method of the distributed simulation system comprises the steps that 1, simulation run is initialized, and model distribution is completed; 2, run simulation is carried out, that is, the client side sends a scheduling instruction to the master control engine, the master control engine receives the scheduling instruction, a first-stage run model is obtained, a drive instruction is sent to the node where the first-stage run model is located, and models on the computational nodes are driven to run; 3, the computational nodes receive the drive instruction to drive the models to run, and result data is generated and output to the master control engine; 4, the master control engine receives the result data and resolves the result data, and downstream model sets are obtained; 6, a downstream model ID set is subjected to traversal; 6, whether the current model is removed or not is judged; 7, whether the number of the downstream model sets is reached or not is judged; 8, the downstream set models are vacant or not is judged, the step 3 is executed, and the method is completed. According to the method, model run efficiency is improved, master control engine loads are reduced, time consumed for model scheduling is shortened, and high universality is achieved.

Description

technical field [0001] The invention relates to a sequential model scheduling method of a distributed simulation system, which belongs to the technical field of complex system simulation. Background technique [0002] The modern simulation environment is becoming more and more complex. With the continuous development of computer technology, more and more disciplines are involved, and the simulation scale is getting larger and larger. Single-machine and single-platform simulation can no longer meet the needs of modern system simulation. In the early 1980s, distributed simulation came into being. [0003] Distributed simulation uses a coordinated structure, standard, protocol and database to interconnect scattered simulation devices through a wide area network or a local area network to form a comprehensive simulation environment that can participate. In a distributed simulation environment, simulation objects or simulation models run on distributed simulation devices. The m...
