ShyLU is a package for solving sparse linear systems. It can be used either as
a preconditioner, or as a solver. Currently, it is recommended as an Ifpack
preconditioner. ShyLU uses a hybrid direct/iterative approach based on Schur
complements. The goal is to provide robustness similar to sparse direct
solvers, but memory usage more similar to preconditioned iterative solvers.
ShyLU was designed as a node-level solver. It can use both MPI and threads in
several ways. ShyLU was designed (a) to solve difficult but medium-size
problems, and (b) to be used as a subdomain solver or smoother for very large
problems within an iterative scheme. It is a purely algebraic method so can be
used as a black-box solver. ShyLU has been particularly successful in
electrical circuit simulation (Xyce).
