| Summary: | Abstract: "We study the parallelization of linearly-implicit extrapolation methods for the solution of large scale systems of differential algebraic equations arising in a method of lines (MOL) treatment of partial differential equations. In our approach we combine a slightly overlapping domain decomposition together with a polynomial block Neumann preconditioner. Through the explicit computation of the matrix products of the preconditioner and the system matrix a significant gain in overall efficiency is achieved for medium-sized problems. The parallel algorithm exhibits a good scalability up to 32 processors on a Cray T3E. Preliminary results for computations on a workstation cluster are reported." |
