reductions/transformation operators - runtime files

RTOp (reduction/transformation operators) provides the basic mechanism for implementing vector operations in a flexible and efficient manner.

libtrilinos-rythmos12

Trilinos transient integrator - runtime files

Rythmos is a transient integrator for ordinary differential equations and differential-algebraic equations with support for explicit, implicit, one-step and multi-step algorithms. The fundamental design of Rythmos is aimed at supporting operator-split algorithms, multi-physics applications, block linear algebra, and adjoint integration.

libtrilinos-teko12

block preconditioners - runtime files

Teko is a package for development and implementation of block preconditioners. This includes support for manipulation and setup of block operators. Furthermore tools exist to support decomposition of a fully coupled operator. Additionally, facilities that allow the construction of approximate inverse operators using the full complement of available preconditioners and solvers are available in Teko. Finally, a small number of generic block preconditioners has been implemented in Teko, including block Jacobi, and block Gauss-Seidel. For the Navier-Stokes equation, Teko has implementations of SIMPLE, PCD and LSC. For details on these methods see Stabilization and Scalable Block Preconditioning for the Navier-Stokes Equations and the references therein.

libtrilinos-triutils12

utilities for Trilinos - runtime files

TriUtils a package of utilities for other Trilinos packages.

libtrilinos-xpetra12

conversion between Epetra and Teuchos objects - runtime files

Xpetra a lightweight wrapper to both Epetra and Tpetra. The Xpetra syntax mirrors that of Tpetra. Xpetra enables algorithm developers to write to a single interface but be able to use either Epetra or Tpetra. Xpetra can also be introduced into existing code to allow for gradual migration.

libtrilinos-zoltan12

parallel dynamic load balancing - runtime files

Zoltan is a toolkit of parallel services for dynamic, unstructured, and/or adaptive simulations. Zoltan provides parallel dynamic load balancing and related services for a wide variety of applications, including finite element methods, matrix operations, particle methods, and crash simulations. Zoltan also provides parallel graph coloring, matrix ordering, unstructured communication tools, and distributed data directories.
