Abstract

Due to the difficulty in simulation for massive array microwave photonics systems, a distributed cross-domain parallel simulation method is proposed in this paper. Firstly, the link parallel computation across system structural domains is achieved based on the independent transmission between channels for each array element in the microwave photonics system. Secondly, the data parallel computing across time domains is achieved by utilizing the relative independence between the pre and post processing times. Furthermore, assisting by a static load balancing strategy to allocate computational resources, these two approaches are effectively combined to achieve high efficient simulation of the microwave photonics system, which addresses the issue of long simulation time caused by large amounts of data and models. For a microwave photonics system with a 64-array and more than 400 models, this technique reduces the simulation time from 39 hours to 23 minutes, resulting in a simulation efficiency improvement of two orders of magnitude. This advancement holds the potential to significantly shorten the development cycle of microwave photonics engineering prototypes.
