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)
