Function Documentation
Gets a neighbor in a given direction.
- 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 dimension and way; only valid for ttorus
| routing_r dtt_rr | ( | long | source, |
| long | destination | ||
| ) |
Generates the routing record for a twisted torus.
This function considers three cases according to the different options of the target dimension of the skews. Z dimension will act as default in case no skew (torus) is considered.
- 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 dtt_rr_unidir | ( | long | source, |
| long | destination | ||
| ) |
Generates the routing record for an unidirectional twisted 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.
