In this letter, a communication-reduced FDFD scheme with improved Generalized Product-type Biconjugate Gradient (IGP-BiCG) method is proposed for parallel scattering simulation in distributed systems. In the proposed scheme, the number of global synchronization points in the linear solver is reduced from 3 to 1 through mathematical restructuring, thereby significantly decreasing the communication overhead in the solution process. The performance of the algorithm is analyzed theoretically, and a numerical experiment is provided, whose results demonstrate its efficiency and scalability in distributed computing environments.
