Hypercube parallel architecture applied to electromagnetic scattering analysis

The authors code the algorithms for two electromagnetic codes, the Numerical Electromagnetic Code (NEC) and the Finite Difference Time Domain Code (FDTD), for the Mark III Hypercube. The execution times for these codes are evaluated. For both codes large speedup factors are found when runs on 32 nod...

More Information
Summary:The authors code the algorithms for two electromagnetic codes, the Numerical Electromagnetic Code (NEC) and the Finite Difference Time Domain Code (FDTD), for the Mark III Hypercube. The execution times for these codes are evaluated. For both codes large speedup factors are found when runs on 32 nodes are compared to runs on one node and to runs on a VAX 11/750. The accuracy of these codes is verified by comparisons with versions running on sequential machines and with published results.< >
