description: "A package for computing and applying algebraic preconditioners in the\
  \ context of preconditioned iterative methods. It is related to the existing Ifpack\
  \ package in Trilinos but provides support for template scalar and ordinal types\
  \ and explicitly relies on Tpetra and Kokkos instead of Epetra. Algebraic preconditioners\
  \ are used by iterative solvers as solution method in engineering and scientific\
  \ applications, including nonlinear equation solving, time integration, sensitivity\
  \ analysis, stability analysis, optimization, and uncertainty quantification."
