Journal ArticleDOI
Approximating the inverse of a matrix for use in iterative algorithms on vector processors
TL;DR: Approximations using the Neumann expansion of the inverse ofA give reasonable forms forM−1 and Computational results using the conjugate gradient method for the “5-point” matrixA are given.
Journal ArticleDOI
Guest Editor's Introduction: Python: Batteries Included
TL;DR: The Python motto "batteries included" is meant to convey the idea that Python comes with everything you need.
Journal ArticleDOI
A simulator for MIMD performance prediction: application to the S-1 MkIIa multiprocessor
TL;DR: A MIMD multiprocessor simulator is described and applied to the investigation of the behavior of four problems on the S-1: The benchmark physics code SIMPLE, a conjugate gradient linear algebra problem, a simple Monte-Carlo problem, and a new method for neutron transport calculations.
Journal ArticleDOI
Why Johnny can't build [portable scientific software]
TL;DR: The author discusses some of the reasons this problem exists and suggests some approaches to solving it that seem promising: the ability to create significant, portable scientific software.
Journal ArticleDOI
Maintaining correctness in scientific programs
TL;DR: The author describes the layered approach that he found to be the most successful in maintaining correctness in the face of rapid change.
