Ruede Institut fuer Informatik Technische Universitaet Muenchen Arcisstr. 21 D-8000 Muenchen 2 Germany e-mail: ruede@informatik.tu-muenchen.de ABSTRACT: Multilevel methods are fast and efficient solvers for a wide range of technical and scientific applications. Their structural complexity makes the construction of powerful multilevel based software difficult. Conventional software engineering concepts do not provide a sufficient basis for the implementation of general, fast, and robust multilevel applications. In particular, there is a severe tradeoff between the generality of such software and its efficiency. These problems can be alleviated on the basis of a consequent data abstraction. To equally satisfy the demands for generality and efficiency it is necessary to introduce a two level software model based on a generation and an execution phase. Suitable implementation techniques are discussed.

Douglas Subject: New paper on an oddball vector method Some Remarks on Completely Vectorizing Point Gauss-Seidel While Using the Natural Ordering Craig C. Douglas Department of Computer Science Yale University P. O. Box 2158 New Haven, CT 06520-2158 E-mail: douglas-craig@cs.yale.edu Abstract: A common statement in papers in the vectorization field is to note that point SOR methods with the natural ordering cannot be vectorized. The usual approach is to re-order the unknowns using a red-black or diagonal ordering and vectorize that. In this paper, we construct a point Gauss-Seidel iteration which completely vectorizes and still uses the natural ordering. The work here also applies to point SOR. When this approach is reasonable to use is also shown.
