Epetra provides the fundamental construction routines and services function that are required for serial and parallel linear algebra libraries. Epetra provides the underlying foundation for all Trilinos solvers.

The GlobiPack package contains a set of interfaces and implementations for 1D globalization capabilities to be used in nonlinear solvers, optimization solvers, and similar algorithms that require globalization methods (e.g. line search and trust region methods). Basic interfaces and a few implementations are present for 1D line search methods appropritate for Newton, quasi-Newton, and nonlinear CG algorithms.

Intrepid is a library of interoperable tools for compatible discretizations of Partial Differential Equations (PDEs). Intrepid is intended primarily for application developers who want to reuse large parts of their existing code frameworks such as I/O, data structures, assembly routines, etc. while gaining access to advanced discretization capabilities provided by Intrepid.

Kokkos implements a programming model in C++ for writing performance portable applications targeting all major HPC platforms. For that purpose it provides abstractions for both parallel execution of code and data management. Kokkos is designed to target complex node architectures with N-level memory hierarchies and multiple types of execution resources. It currently can use OpenMP, Pthreads and CUDA as backend programming models.

Komplex is a complex linear solver package. Solves complex-valued linear systems via equivalent real formulations.

"We are all different!" Geneticists agree to this. Even twins, who are said to be identical are on a molecular level only "mostly" identical. And even within the exact same individual, healthy cells acquire mutations such that we are all genetic mosaics. Changes to individual cells may be induced by environmental factors, e.g. like UV light, or happen sporadically as mishaps during cellular divisions.
