Data Abstraction Techniques for Multilevel Algorithms

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.

Some Remarks on Completely Vectorizing Point Gauss-Seidel While Using the
Natural Ordering

Craig C. Douglas

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.
