Development of computer science techniques has significantly enhanced
computational electromagnetic methods in recent years. The multi-core
CPU computers and multiple CPU work stations are popular today for
scientific research and engineering computing. How to achieve the best
performance on the existing hardware platforms, however, is a major
challenge. In addition to the multi-core computers and multiple CPU
workstations, distributed computing has become a primary trend due to
the low cost of the hardware and the high performance of network
systems. In this book we introduce a general hardware acceleration
technique that can significantly speed up FDTD simulations and their
applications to engineering problems without requiring any additional
hardware devices.
