Case studies on the development of ScaLAPACK and the NAG Numerical PVM Library
[chapter]
1997
IFIP Advances in Information and Communication Technology
Preserved Fulltext
In this paper we look at the development of ScaLAPACK, a software library for dense and banded numerical linear algebra, and the NAG Numerical PVM Library, which includes software for dense and sparse ...
Both libraries are aimed at distributed memory machines, including networks of workstations. The paper concentrates on the underlying design and the testing of the libraries. ...
ACKNOWLEDGMENTS We wish to thank our ScaLAPACK colleagues at the University of Tennessee at Knoxville and the University of California at Berkeley, as well as colleagues at NAG involved with the development ...
