Parallel direct linear system solvers -- a survey☆

TL;DR: This paper is a survey of direct parallel algorithms for solving systems of linear equations, and states their resulting speedup over the corresponding sequential algorithms, and evaluates their numerical stability, whenever possible.

Environment Parameters and Basic Functions for Floating-Point Computation

TL;DR: A language-independent proposal for environment parameters and basic functions for floating-point computation is presented, which can be used to write portable and robust codes that deal intimately with thefloating-point representation.

Evaluation and enhancements of some control volume finite-element methods—part 1. convection-diffusion problems

TL;DR: In this paper, the authors examined three control volume finite-element methods (CVFEMs) for convection-diffusion problems and found that significant improvements in the accuracy of the solutions can often be obtaine...

Quadratic convergence in interval arithmetic, part II

TL;DR: In this paper, the authors investigated the effect of dependence on the error of one operation in an interval arithmetic procedure and proved the quadratic convergence of the "centered form" and of a method of Hansen and Smith for solving linear algebraic systems.

Singular value decomposition and least squares solutions

TL;DR: The decomposition of A is called the singular value decomposition (SVD) and the diagonal elements of ∑ are the non-negative square roots of the eigenvalues of A T A; they are called singular values.

Hyperquad simulation and speciation (HySS): a utility program for the investigation of equilibria involving soluble and partially soluble species

TL;DR: Hyperquad simulation and speciation (HySS) as mentioned in this paper is a computer program written for the Windows operating system on personal computers which provides simulating titration curves and a system for providing speciation diagrams.

What every computer scientist should know about floating-point arithmetic

TL;DR: This paper presents a tutorial on the aspects of floating-point that have a direct impact on designers of computer systems, and concludes with examples of how computer system builders can better support floating point.

Generalization of backpropagation with application to a recurrent gas market model

TL;DR: This paper will derive a generalization of backpropagation to recurrent systems (which input their own output), such as hybrids of perceptron-style networks and Grossberg/Hopfield networks, and does not require the storage of intermediate iterations to deal with continuous recurrence.

An algorithm for reducing the bandwidth and profile of a sparse matrix

TL;DR: Extensive testing on finite element matrices indicates that the algorithm typically produces bandwidth and profile which are comparable to those of the commonly-used reverse Cuthill–McKee algorithm, yet requires significantly less computation time.
