BSmain_perm(3)                   BlockSolve95                   BSmain_perm(3)

NAME
       BSmain_perm - Permute the matrix for efficient parallel execution

INPUT PARAMETERS
       procinfo
              - the usual processor context information
       A      - the sparse matrix

RETURNS
       the sparse matrix permuted into an efficient structure

NOTES
         (1) The sparse matrix must be symmetric in structure
         (2) The graph associated with the sparse matrix must be connected
         (3) max_inode_size and max_clique_size should usually be set to
             INT_MAX (they are kept in the context)
         (4) see the manual for more details on what algorithms BSmain_perm
       uses
         (5) the context variable "retain" will indicate whether or not
             some extra data should be kept around to allow for fast
       permutation
             of a matrix with the same structure in the future

SYNOPSIS
