9504074 Gandhi This research will compare several methods of parallelizing the EM FDTD code for large-scale man moll studies. Heterogeneous workstation clusters will be used to study code portability, efficiency, and scalability. This will be compared to use of High Performance Fortran (HPF) and also massively parallel machines. Visualization of the large-scale output data and subgridding of the FDTD lattice will also be parallelized. With the high-resolution model made possible by the parallel code, coupling of power lines to the pineal and pituitary glands, which may be implicated in EM biointeraction, will be studied. Next-generation cellular telephones at 1900 MHz will be examined, and a library of impulse responses will be developed, allowing analysis of coupling of the body to any waveform up to 3 GHz.

9504074甘地这项研究将比较几种并行化EMFDTD代码的方法，以进行大规模的人体模型研究。异类工作站集群将用于研究代码的可移植性、效率和可伸缩性。这将与使用高性能Fortran(HPF)和大规模并行机进行比较。大规模输出数据的可视化和FDTD网格的亚网格化也将并行化。利用并行程序实现的高分辨率模型，将研究电力线与松果体和脑垂体腺的耦合，这可能与EM的生物相互作用有关。将研究1900 MHz的下一代蜂窝电话，并开发脉冲响应库，允许分析身体与高达3 GHz的任何波形的耦合。
