16 Introduction to BCSLIB-EXT
Overview
This chapter provides a brief overview of HP’s implementation of BCSLIB-EXT
functionality.
BCSLIB-EXT is a set of subroutines for solving large sparse linear algebra
problems and it has been developed by Boeing Phantom Works Mathematics
and Computing Technology (http://www.boeing.com/phantom). BCSLIB-EXT is
intended to solve problems arising out of static and frequency response analysis
(by solving linear systems) and problems for buckling and vibration studies (by
solving generalized eigenvalue problems). BCSLIB-EXT is based on the
multifrontal algorithm and the block shifted and inverted Lanczos algorithm.
BCSLIB-EXT is designed for very large sparse problems and supports
out-of-core functionality.
HP MLIB is fully compliant with BCSLIB-EXT Version 4.2. HP MLIB extends
the functionality of BSCLIB-EXT by adding support for integers that are 8
bytes in length. This allows users to solve even larger problems.
