Detailed Description

The MFEM SuperLU Direct Solver class.

The mfem::SuperLUSolver class uses the SuperLU_DIST library to perform LU factorization of a parallel sparse matrix. The solver is capable of handling double precision types. It is currently maintained by Xiaoye Sherry Li at NERSC, see http://crd-legacy.lbl.gov/~xiaoye/SuperLU/.
