Exploit the
naturally parallel properties of the Finite Difference Time Domain (FDTD)
algorithm to improve existing Time Domain Field Solvers, and to efficiently
address more complex and large problem sets with this cutting-edge reference.
The book shows you how to apply MPI and MPICH to develop a parallel FDTD code,
and to assemble the hardware to run it in parallel. In addition to introducing
the basic concepts of the MPI library, parallel data structures, and parallel
architectures, this practical resource gives you detailed guidance on
implementing parallel FDTD using parallel data-exchanging code.
You learn how to
interconnect PCs in a cluster to efficiently execute FDTD in parallel. The book
provides you with hands-on examples using large finite antenna arrays that
illustrate the power of parallel FDTD. You also find practical strategies for
carrying out parallel FDTD and learn about the BOR/FDTD technique and its
parallel implementation. The book concludes with instructions on downloading,
installing, and setting up the MPI library on both Windows and Linux systems,
as well as a handy tutorial on MPI data types, operators, and functions in
FORTRAN and C.
