MachineAllocationController
(thread_name, hostname=None, connection_data=None)[source]¶ Bases:
spinn_front_end_common.abstract_models.abstract_machine_allocation_controller.AbstractMachineAllocationController
How to manage the allocation of a machine so that it gets cleaned up neatly when the script dies.
Parameters: thread_name (str) – -
create_transceiver
()[source]¶ Create a transceiver for talking to the allocated machine, and make sure everything is ready for use (i.e. boot and discover connections if needed).
Return type: Transceiver
-
open_eieio_connection
(chip_x, chip_y)[source]¶ Open a connection to a specific ethernet chip for EIEIO. Caller will have to arrange for SpiNNaker to pay attention to the connection.
Parameters: Return type:
-
open_eieio_listener
()[source]¶ Open an unbound EIEIO connection.
Return type: EIEIOConnection

MachineDataSpecableVertex
[source]¶ Bases:
spinn_front_end_common.abstract_models.abstract_generates_data_specification.AbstractGeneratesDataSpecification
Support for a vertex that simplifies generating a data specification.
-
generate_data_specification
(spec, placement)[source]¶ Generate a data specification.
Parameters: - spec (DataSpecificationGenerator) – The data specification to write to
- placement (Placement) – The placement the vertex is located at
-
generate_machine_data_specification
(spec, placement, iptags, reverse_iptags)[source]¶ Parameters: - spec (DataSpecificationGenerator) – The data specification to write into.
- placement (Placement) – Where this node is on the SpiNNaker machine.
- iptags (iterable(IPTag) or None) – The (forward) IP tags for the vertex, if any
- reverse_iptags (iterable(ReverseIPTag) or None) – The reverse IP tags for the vertex, if any

TDMAAwareApplicationVertex
(label, max_atoms_per_core, splitter=None)[source]¶ Bases:
pacman.model.graphs.application.application_vertex.ApplicationVertex
An application vertex that contains the code for using TDMA to spread packet transmission to try to avoid overloading any SpiNNaker routers.
Parameters: -
generate_tdma_data_specification_data
(vertex_index)[source]¶ Generates the TDMA configuration data needed for the data spec.
Parameters: vertex_index (int) – the machine vertex index in the pop Returns: array of data to write. Return type: list(int)
-
get_n_cores
()[source]¶ Get the number of cores this application vertex is using in the TDMA.
Returns: the number of cores to use in the TDMA Return type: int
-
get_n_phases
()[source]¶ Compute the number of phases needed for this application vertex. This is the maximum number of packets any machine vertex created by this application vertex can send in one simulation time step, which defaults to the number of atoms in the graph.
Return type: int
-
get_tdma_provenance_item
(x, y, p, desc_label, tdma_slots_missed)[source]¶ Get the provenance item used for the TDMA provenance.
Parameters:
-
set_initial_offset
(new_value)[source]¶ Sets the initial offset.
Parameters: new_value (int) – the new initial offset, in clock ticks
-
