Scotch Brand 5.1.10 - Manual (Page 76)

(i + 1) of each node at level i, and linktab[i] is the cost of communication
between processors the first common ancestor of which belongs to this level.
See Section 5.4.2, page 24, for an example of such an architecture.
Return values
SCOTCH archTleaf returns 0 if the tree-leaf target architecture has been suc-
cessfully built, and 1 else.
7.4.14 SCOTCH archTorus2D
Synopsis
int SCOTCH archTorus2D (SCOTCH Arch * archptr,
const SCOTCH Num xdimval,
const SCOTCH Num ydimval)
scotchfarchtorus2d (doubleprecision (*) archdat,
integer*num xdimval,
integer*num ydimval,
integer ierr)
Description
The SCOTCH archTorus2D routine fills the SCOTCH Arch structure pointed to
by archptr with the description of a 2D torus architecture with xdimval ×
ydimval
processors.
Return values
SCOTCH archTorus2D returns 0 if the 2D torus target architecture has been
successfully built, and 1 else.
