Stokhos is a package for intrusive stochastic Galerkin uncertainty quantification methods. It provides methods for computing well-known intrusive stochastic Galerkin projections such as Polynomial Chaos and Generalized Polynomial Chaos, interfaces for forming the resulting nonlinear systems, and linear solver methods for solving block stochastic Galerkin linear systems.

The package Stratimikos contains a unified set of Thyra-based wrappers to linear solver and preconditioner capabilities in Trilinos. The Stratimikos package is also a place where unified testing of linear solvers and preconditioners can be performed.

MUMPS implements a direct solver for large sparse linear systems, with a particular focus on symmetric positive definite matrices. It can operate on distributed matrices e.g. over a cluster. It has Fortran and C interfaces, and can interface with ordering tools such as Scotch.
