An Adaptive Parallel Integrator of Ordinary Differential Equations System for Space Experiment Simulation
For developers of space simulation software, this work offers a practical parallelization approach, but it is incremental as it applies known thread-based methods to a specific domain.
The paper proposes a parallel integrator for solving ordinary differential equations to simulate space object motion, using thread-based parallelization and a synchronization method to reduce calculation time on multi-core processors.
Different possible sources are discussed for enhancement of the calculation time when solving ordinary differential equations systems to forecast space objects' motion. This paper presents an approach for building an integrator of ordinary differential equations systems for simultaneous solving of motion equations of multiple objects. A parallelization of calculation on the base of threads is offered. A method for synchronization is presented. The technological advance and the invasion of multi-core processors make actual the examined approach for developing an integrator of ordinary differential equations systems.
