Outline of Final Research Achievements

Parallel computations by the use of multi-scale descriptions for quantum systems, two-phase fluids, and sound/fluid complex systems have been executed. Through these studies, it was established that the space-time parallel method is effective to systems described by non-parabolic partial differential equations. On the other hand, it was also revealed that systems under ordinary differential equations are difficult to be parallelized by the parallel-in-time method. This is because convergence property is poor and an application area is narrow. In this study, we demonstrated the poor convergence in self-propelled particle systems when we parallelize them with the parallel-in-time method.
