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  permuta-
       tion
	     of	a matrix with the same structure in the	future

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

	BlockSolve95/src/BSmain_perm.c
