class lava.magma.core.sync.domain.SyncDomain(name, protocol=None, processes=None)

Bases: object

Specify to run a group of Processes using a specific SyncProtocol.

A SyncProtocol defines how and when Processes are synchronized and communication is possible. The SyncDomain maps a list of Processes to a given SyncProtocol.

Parameters:

  • name (str) – Name of the SyncDomain.

  • protocol (AbstractSyncProtocol) – SyncProtocol the Processes are mapped to.

  • processes (ty.List[AbstractProcess]) – List of Processes to run in the given SyncProtocol.

class lava.magma.core.sync.protocol.AbstractSyncProtocol

Bases: object

Base class for SyncProtocols.

A SyncProtocol defines how and when the Processes in a SyncDomain are synchronized and communication is possible. SyncProtocols need to implement the runtime_service()’ method which returns a map between hardware resources and the corresponding `RuntimeServices.

For example:

>>> @property
>>> def runtime_service(self) -> ty.Dict[Resource, AbstractRuntimeService]:
>>>     return {CPU: LoihiPyRuntimeService,
>>>             LMT: NxSdkRuntimeService,
>>>             NeuroCore: NxSdkRuntimeService,
>>>             Loihi1NeuroCore: NxSdkRuntimeService,
>>>             Loihi2NeuroCore: NxSdkRuntimeService}

The phases of execution and synchronizations points are implemented in the specific RuntimeService.
