Design technology for building wireless systems (tutorial)

Solving large sparse systems of linear equations is at the core of many problems in engineeringand scienti#c computing. It has long been a challenge to develop parallel formulations ofsparse direct solvers due to several di#erent complex steps involved in the process. In thispaper, we describe one of the #rst e#cient, practical, and robust parallel solvers for sparsesymmetric positive de#nite linear systems that wehave developed and discuss the algorithmicand implementation issues involved ...
