BULK SYNCHRONOUS PARALLELIZATION OF INDUSTRIAL ELECTROMAGNETIC SOFTWARE

The parallelization of existing/industrial electromagnetic software us ing the bulk synchronous parallel (BSP) computation model is presented . The software employs the finite element method with a preconditioned conjugate gradient-type solution for the resulting linear systems of equations. A geometric mesh-partitioning approach is applied within th e BSP framework for the assembly and solution phases of the finite ele ment computation. This is combined with a nongeometric, data-driven pa rallel quadrature procedure for the evaluation of right-hand-side term s in applications involving coil fields. A similar parallel decomposit ion is applied to the parallel calculation of electron beam trajectori es required for the design of tube devices. The BSP parallelization ap proach adopted is fully portable, conceptually simple, and cost-effect ive, and it can be applied to a wide range of finite element applicati ons not necessarily related to electromagnetics.
