pacman.model.routing_info package¶
Module contents¶
-
class
pacman.model.routing_info.
BaseKeyAndMask
(base_key, mask)[source]¶ Bases:
object
A Key and Mask to be used for routing.
Parameters: Raises: PacmanConfigurationException – If key & mask != key i.e. the key is not valid for the given mask
-
get_keys
(key_array=None, offset=0, n_keys=None)[source]¶ Get the ordered list of keys that the combination allows.
Parameters: - key_array (ndarray(int)) – Optional array into which the returned keys will be placed
- offset (int) – Optional offset into the array at which to start placing keys
- n_keys (int) – Optional limit on the number of keys returned. If less than this number of keys are available, only the keys available will be added
Returns: A tuple of an array of keys and the number of keys added to the array
Return type:
-

MachineVertexRoutingInfo
(keys_and_masks, partition_id, machine_vertex, index)[source]¶ Bases:
pacman.model.routing_info.vertex_routing_info.VertexRoutingInfo
Associates a machine vertex and partition identifier to its routing information (keys and masks).
Parameters: - keys_and_masks (iterable(BaseKeyAndMask)) – The keys allocated to the machine partition
- partition_id (str) – The partition to set the keys for
- machine_vertex (MachineVertex) – The vertex to set the keys for
- index (int) – The index of the machine vertex
-
machine_vertex
¶ The machine vertex.
Return type: MachineVertex
-
vertex
¶ The vertex of the information.
Return type: ApplicationVertex or MachineVertex

RoutingInfo
[source]¶ Bases:
object
An association of machine vertices to a non-overlapping set of keys and masks.
-
add_routing_info
(info)[source]¶ Add a routing information item.
Parameters: info (VertexRoutingInfo) – The routing information item to add Raises: PacmanAlreadyExistsException – If the partition is already in the set of edges
-
get_first_key_from_pre_vertex
(vertex, partition_id)[source]¶ Get the first key for the partition starting at a vertex.
Parameters: - vertex (AbstractVertex) – The vertex which the partition starts at
- partition_id (str) – The ID of the partition for which to get the routing information
Returns: The routing key of the partition
Return type:
-
get_routing_info_from_pre_vertex
(vertex, partition_id)[source]¶ Get routing information for a given partition_id from a vertex.
Parameters: - vertex (AbstractVertex) – The vertex to search for
- partition_id (str) – The ID of the partition for which to get the routing information
-

AppVertexRoutingInfo
(keys_and_masks, partition_id, app_vertex, machine_mask, n_bits_atoms, max_machine_index)[source]¶ Bases:
pacman.model.routing_info.vertex_routing_info.VertexRoutingInfo
-
vertex
¶ The vertex of the information.
Return type: ApplicationVertex or MachineVertex
