Abstract
- The upwind leapfrog scheme for electromagnetic scattering is briefly described. Its application to the 3D Maxwell`s time domain equations is shown in detail. The scheme`s use of upwind characteristic variables and a narrow stencil result in a smaller demand in communication overhead, making it ideal for implementation on distributed memory parallel computers. The algorithm`s implementation on two message passing computers, a 1024-processor nCUBE 2 and a 1840-processor Intel Paragon, is described. Performance evaluation demonstrates that the scheme performs well with both good scaling qualities and high efficiencies on these machines.
