Welcome to the Amesos Home

Amesos is the Direct Sparse Solver Package in Trilinos. The goal of Amesos is to make AX=B as easy as it sounds, at least for direct methods. Amesos provides clean and consistent interfaces to the following third party libraries:

LAPACK
UMFPACK version 4.4
TAUCS version 2.2
PARDISO version 1.2.3 (outdated)
SuperLU version 4.1
SuperLU_DIST version 2.5
DSCPACK version 1.0
SCALAPACK version 1.7
MUMPS version 4.7.3 (experimental support for version 4.9)

Amesos comes with a serial direct solver, called KLU, and a parallel direct solver, called Paraklete, which can be used to solve sparse linear systems. Each interface can be enabled at configure time. Amesos also offers an interface to Python, thus making all the supported interfaces available within the Python interpreter; see the PyTrilinos package for more details.
