Elemental is a modern C++ library for distributed-memory dense and sparse-direct linear algebra. The library was initially released in Elemental: A new framework for distributed memory dense linear algebra and has recently absorbed the functionality from the sparse-direct solver Clique.

Please visit the download page for download instructions, but note that 0.85 wil be the first release containing sparse-direct support.

The documentation for the development version of Elemental is built using Sphinx.

Implementations (in alphabetical order):

• NuLAB
• PaRSEC/DPLASMA
• PLAPACK
• ScaLAPACK (and the extension, ELPA)

Wrappers:

• PETSc
• Trilinos

Note that PETSc contains an interface for some of Elemental's functionality.
