Title: Parallel implementation of the coupled harmonic oscillator,
Abstract: This article presents the parallel implementation of the coupled harmonic
oscillator. From the analytical solution of the coupled harmonic oscillator,
the design parameters are obtained. After that, a numerical integration of the
system with MATLAB, which is used as a tool of benchmark evaluation, is
performed. Next, parallel implementation is performed using a well-known
approach like OpenMP and WinAPI. Taking into account the errors of basic
parameters of the simulated process, the generated oscillations of the proposed
parallel realization are almost identical to the actual solution of the
harmonic oscillator model. Test ways to optimize the parallel architecture of
computing processes for software implementations of the considered application
is carried out. The developed model is used to study a fixed priority
scheduling algorithm for real-time parallel threads execution. The proposed
parallel implementation of the considered dynamic system has an independent
value and can be considered as a test for determining the characteristics of
multi-core systems for time-critical simulation problems. Keywords: Harmonic
