What is FDTD?

FDTD(Finite-difference time-domain) method is a numerical analysis technique used for modeling computational electrodynamics. The idea is rather simple, but this method involves a lot of computation, which makes it sometimes intolerably slow to run on a typical PC. As the development of parallel computation, we may run FDTD program on a distributed system. Though some business software has good implementation on this problem, it is really difficult to find an open-source implementation. What's more, the numerical simulation of the spread of electromagnetic field is a pretty basic problem, so that many researchers may want to use it. Therefore, we decided to work on this problem and publish our code.

Our code turns to have a good scalability. Experiments show that we achieves an 6X speedup on a cluster consisting of 8 computing nodes.

We recommand you to run this code on a Linux cluster(or a single PC) with MPI environment.
