Renowned Parallel-in-Space/Time (PinST) methods such as the parareal method and the MGRIT method are compelling with implicit time-marching schemes. However, PinST methods with explicit time-marching have been challenging due to the restriction of the Courant-Friedrichs-Lewy (CFL) condition. Moreover, explicit schemes are highly scalable in the space dimension, which is more efficient than existing PinST methods. In this research, we propose a method based on the parareal algorithm, which is highly scalable and complies with the CFL condition. We also demonstrate the performance utilizing two explicit time-marching models. |
