:mod:`kwant.solvers.mumps` -- High performance sparse solver based on MUMPS
===========================================================================
.. module:: kwant.solvers.mumps
This solver uses `MUMPS `_. (Only the
sequential, single core version of MUMPS is used.) MUMPS is a very efficient
direct sparse solver that can take advantage of memory beyond 3GiB for the
solution of large problems. Furthermore, it offers a choice of several
orderings of the input matrix some of which can speed up a calculation
significantly.
Compared with the :mod:`default solver `, this module
adds several options that may be used to fine-tune performance. Otherwise the
interface is identical. These options can be set and queried with the
following functions.
.. autofunction:: options
.. autofunction:: reset_options
