Abstract
A cell center, upwind biased, spatially third-order and temporally second-order finite volume procedure for solving the Maxwell equations in time domain has been ported to a Intel Touchstone Delta and a Paragon multicomputer. Using a one-dimensional domain partition scheme, the computer code has attained a data processing rate of 7.56 Gigaops on the 512 nodes of the Delta and 3.56 Gigaops on the 179 nodes of the Paragon XP/S systems. The high parallel efficiency of the present computer program however, is sustainable only up to a limited size of addressable memory (nodes × 48 × 96). The scalable performance range of the present code is significantly extended by operating on the Paragon system at the present time.
