NAME

BSmain_perm - Permute the matrix for efficient parallel execution

CONTENTS

Input Parameters
Returns
Notes
Synopsis
Location

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

BSpar_mat *BSmain_perm(BSprocinfo *procinfo, BSspmat *A)
