Abstract

The invention discloses a multi-core parallel method for continuous system simulation based on TBB threading building blocks. The method mainly comprises the following steps: step 1, building a TBB parallel computing platform; step 2, constructing a parallel ParaODES template catalog; step 3, carrying out model initialization; step 4, initializing TBB task scheduling; step 5, judging a simulationtime scope; step 6, calling the parallel ParaODES template; step 7, transferring a simulation result; and step 8, ending TBB task scheduling. The method can realize parallelization processing for continuous system simulation by TBB, improve the simulation calculating speed, meet the requirement of simulation real-time property, and shorten the simulation research period; by parallelization processing with the TBB, the method has simple and flexible process, easy operation and good expansibility; and the TBB adopts a multi-core architecture, which conforms to the development direction from thecurrent parallel technology to a multi-core platform.

Description

technical field [0001] The invention relates to a continuous system simulation multi-core parallel method based on a TBB thread building block (Thread Building Blocking), which belongs to the field of computer simulation and algorithm optimization. Background technique [0002] Continuous system simulation is widely used in fields such as aviation, aerospace, meteorology and electronics. With the development of these disciplines and technologies, the simulation models thus established are becoming more and more complex, and the amount of simulation calculations is increasing. [0003] Continuous system simulation usually uses differential equations to establish mathematical models, and differential equations have mature numerical solutions, such as Runge-Kutta method, Adams method, etc. However, the traditional serial method takes too long to calculate when solving large-scale problems, and it is difficult to meet the real-time requirements of simulation. Some complex probl...
