Function Documentation

routing_r mesh_rr	(	long	source,
		long	destination
	)

Generates the routing record for a mesh.

Parameters:

source	The source node of the packet.
destination	The destination node of the packet.

Returns:

The routing record needed to go from source to destination.

long torus_neighbor	(	long	ad,
		dim	wd,
		way	ww
	)

Obtains a neighbor node in torus & mesh topologies.

Given a node address "ad", a direction "wd" (X,Y or Z) and a way "ww" (UP or DOWN) returns the address of the neighbor in that direction and way; only valid for torus but usable also for mesh.

Parameters:

ad	A node address.
wd	A dimension (X,Y or Z).
ww	A way (UP or DOWN).

Returns:

The address of the neighbor in that direction.

routing_r torus_rr	(	long	source,
		long	destination
	)

Generates the routing record for a torus.

Parameters:

source	The source node of the packet.
destination	The destination node of the packet.

Returns:

The routing record needed to go from source to destination.

routing_r torus_rr_unidir	(	long	source,
		long	destination
	)

Generates the routing record for an unidirectional torus.

Parameters:

source	The source node of the packet.
destination	The destination node of the packet.

Returns:

The routing record needed to go from source to destination.
