Abstract
In a multi-system heterogeneous LAN,the lack of interoperability for the MPI program in the different operating environments makes it difficult to make full use of the LAN computing resources in the parallel Finite Difference Time Domain(FDTD)algorithm.To resolve this problem,a new method of using Serverce Message Block(SMB)protocol to realize heterogeneous FDTD computing was presented,and by some means such as memory-file access,memory-mapped array and redundancy computing,the impact of SMB communication latency upon the parallel performance was released.Some computed examples were given to prove the feasibility and accuracy of this method.The numerical results show that performance indexes,such as speedup,parallel efficiency,etc.are close to the isomorphism FDTD computing using MPI.
