MUMPS (MUltifrontal Massively Parallel Solver)

MUMPS is a parallel software package (Fortran 90, MPI) for the solution of sparse systems of linear equations. Its performance is very competitive and it has a large number of functionalities, including:

• types of systems: symmetric (positive definite or not), or unsymmetric,
• various matrix input formats (assembled or elemental, distributed or centralized),
• threshold partial pivoting for robustness,
• partial factorization (computation of a Schur complement matrix),
• real or complex arithmetic,
• fully asynchronous approach with distributed dynamic scheduling,
• C or Fortran 90 interface,
• ...

MUMPS is available free of charge.
