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.

this package contains the dynamic libraries.
