NEWARK, Del., Aug. 16, 2006 -- EM Photonics Inc., a provider of accelerated hardware technologies, has released FastFDTD, a free two- and three-dimensional accelerated FDTD (finite-difference time-domain) solver based on GPU (graphics card) technology. FastFDTD is the latest in a line of FDTD acceleration products offered by EM Photonics and its OEM partners, including EMPLab Accelerator, EMPremier Workstation, OptiFDTD Max and the Celerity platform.

The FastFDTD toolkit contains all files and documentation necessary to accelerate FDTD computations using a simple input file format. No proprietary hardware is required, and it can be used with any supported graphics card. The 2-D and 3-D solvers include a variety of sources and materials, and more are being added, the company said.

Eric Kelmelis, vice president of EM Photonics, said, "We decided to release our GPU-based FDTD accelerator free of charge to demonstrate the power of application acceleration with alternative computational platforms. This solver shows a single graphics card running 20 to 30 times faster than an optimized software implementation. Our focus will remain on pushing the boundaries of this technology and accelerating other applications with commodity hardware devices, such as graphics cards and FPGAs."

EM Photonics is demonstrating FastFDTD at SPIE's Optics and Photonics conference, being held this week in San Diego, Calif. (booth 433).
