<a href="https://trilinos.org/" target="_top">Trilinos</a> is a
software package that provides lots of functionality for linear
- algebra, among other things. For example, it includes implementations of a variety of
- linear solvers, as well as various different sparse and dense matrix and
- vector formats. Trilinos also has many subpackages that deal with
- problems that go far beyond linear algebra, for example nonlinear
+ algebra, among other things. For example, it includes implementations of
+ a variety of linear solvers, as well as various different sparse and dense
+ matrix and vector formats. Trilinos also has many subpackages that deal
+ with problems that go far beyond linear algebra, for example nonlinear
solvers, automatic differentiation packages, uncertainty propagation
engines, etc. Of particular interest to deal.II is their ability to
provide this functionality both on sequential and parallel (using MPI)
- computers. Compared to <a href="http://www.mcs.anl.gov/petsc/"
- target="_top">PETSc</a>, which is written in C, Trilinos is written in
- C++ and can be
- considered to be a more modern version of PETSc though both packages are
- under continuing development at their respective national laboratories.
