! MODULE par_solve_mumps
! ==================
!
! Interface for MUMPS (Multifrontal Massively Parallel Solver),
! a package for solving linear systems with unsymmetric, symmetric
! positive definite and general symmetric matrices. The solution
! is based on a multifrontal technique which is a direct method
! using the LU or the LDL' factorization of the matrix. For further
! informations about MUMPS refer to the project web sites:
!
! http://www.enseeiht.fr/apo/MUMPS/
! http://www.ens-lyon.fr/~jylexcel/MUMPS
!
! The interface allows to store up to max_save factorized linear
! systems for subsequent solutions with different rhs.
