SCOTCH stratGraphMap
Synopsis
int SCOTCH stratGraphMap (SCOTCH Strat *
straptr,
const char *
string)
scotchfstratgraphmap (doubleprecision (*)
stradat,
character (*)
string,
integer
ierr)
Description
The
SCOTCH stratGraphMap
routine fills the strategy structure pointed to by
straptr
with the graph mapping strategy string pointed to by
string
. From
this point, the strategy structure can only be used as a mapping strategy, to
be used by function
SCOTCH graphMap
, for instance.
When using the C interface, the array of characters pointed to by
string
must be null-terminated.
Return values
SCOTCH stratGraphMap
returns 0 if the strategy string has been successfully
set, and 1 else.

SCOTCH stratGraphMapBuild
Synopsis
int SCOTCH stratGraphMapBuild (SCOTCH Strat *
straptr,
const SCOTCH Num
flagval,
const SCOTCH Num
partnbr,
const double
balrat)
scotchfstratgraphmapbuild (doubleprecision (*)
stradat,
integer*
num
flagval,
integer*
num
partnbr,
doubleprecision
balrat,
integer
ierr)
Description
The
SCOTCH stratGraphMapBuild
routine fills the strategy structure pointed
to by
straptr
with a default mapping strategy tuned according to the pref-
erence flags passed as
flagval
and to the desired number of parts
partnbr
and imbalance ratio
balrat
. From this point, the strategy structure can
only be used as a mapping strategy, to be used by function
SCOTCH graph
Map
, for instance. See Section 7.3.1 for a description of the available flags.
Return values
SCOTCH stratGraphMapBuild
returns 0 if the strategy string has been suc-
cessfully set, and 1 else.
