libtrilinos-teko-13.2
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-teuchos-13.2
common tools for Trilinos - runtime files
Teuchos provides a suite of common tools for Trilinos for developers to use.
These tools include BLAS/LAPACK wrappers, smart pointers, parameter lists, XML
parsers, etc.
libtrilinos-xpetra-13.2
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.
