00031 // Description: This file contains the class definition for DistributedSuperLU.
00032 // A DistributedSuperLU object can be constructed to solve a SparseGenColLinSOE
00033 // object. It obtains the solution by making calls on the
00034 // the SuperLU library developed at UC Berkeley by Prof. James Demmel, 
00035 // Xiaoye S. Li and John R. Gilbert.
00036 // The SuperLU library contains a set of subroutines to solve a sparse
00037 // linear system  $AX=B$. It uses Gaussian elimination with partial
00038 // pivoting (GEPP). The columns of A may be preordered before
00039 // factorization; the preordering for sparsity is completely separate
00040 // from the factorization and a number of ordering schemes are provided.
