Interface DistributedBackend

All Superinterfaces:

AlgorithmProvider, Backend, ComputeBackend, DistributedComputingProvider

All Known Implementing Classes:

MPIDistributedBackend, SparkDistributedBackend

public interface DistributedBackend
extends ComputeBackend, DistributedComputingProvider

Backend interface for distributed computing systems.

Extends ComputeBackend to bridge the distributed computing subsystem with the unified backend infrastructure. Also implements DistributedComputingProvider so that distributed backends are discoverable via the algorithm provider registry.

Method Summary

Modifier and Type	Method	Description
default ExecutionContext	createContext()	Default implementation of ComputeBackend.createContext().
default HardwareAccelerator	getAcceleratorType()	Returns the type of hardware accelerator used by this backend.
default String	getAlgorithmType()	Returns the unique category of the algorithm.
int	getNodeCount()	Returns the number of available distributed nodes.
default int	getPriority()	Resolves the diamond-conflict between ComputeBackend (via Backend) and DistributedComputingProvider (via AlgorithmProvider), both of which define getPriority().
default String	getType()	Returns the backend type category (e.g., "plotting", "molecular", "tensor", "math").
boolean	isAvailable()	Resolves the method conflict between invalid reference Backend#isAvailable() and AlgorithmProvider.isAvailable().
default void	shutdown()	Called when the application is shutting down or the backend is being replaced.
default boolean	supportsParallelOps()	Checks if this backend supports parallel operations.

Method Details

getNodeCount

int getNodeCount()

Returns the number of available distributed nodes.

Returns:

the node count

getType

default String getType()

Description copied from interface: Backend

Returns the backend type category (e.g., "plotting", "molecular", "tensor", "math").

Specified by:

getType in interface Backend

Specified by:

getType in interface ComputeBackend

supportsParallelOps

default boolean supportsParallelOps()

Description copied from interface: ComputeBackend

Checks if this backend supports parallel operations.

Specified by:

supportsParallelOps in interface ComputeBackend

Returns:

true if parallel execution is supported

getAcceleratorType

default HardwareAccelerator getAcceleratorType()

Description copied from interface: ComputeBackend

Returns the type of hardware accelerator used by this backend.

Specified by:

getAcceleratorType in interface ComputeBackend

Returns:

the accelerator type

getAlgorithmType

default String getAlgorithmType()

Description copied from interface: AlgorithmProvider

Returns the unique category of the algorithm.

Specified by:

getAlgorithmType in interface AlgorithmProvider

getPriority

default int getPriority()

Resolves the diamond-conflict between ComputeBackend (via Backend) and DistributedComputingProvider (via AlgorithmProvider), both of which define getPriority().

Specified by:

getPriority in interface AlgorithmProvider

Specified by:

getPriority in interface Backend

isAvailable

boolean isAvailable()

Resolves the method conflict between

invalid reference

Backend#isAvailable()

and AlgorithmProvider.isAvailable().

Specified by:

isAvailable in interface AlgorithmProvider

Specified by:

isAvailable in interface Backend

createContext

default ExecutionContext createContext()

Default implementation of ComputeBackend.createContext().

Wraps the result of DistributedComputingProvider.createDistributedContext() in a DistributedExecutionContext adapter.

Specified by:

createContext in interface ComputeBackend

Returns:

new execution context

shutdown

default void shutdown()

Description copied from interface: Backend

Called when the application is shutting down or the backend is being replaced. Use this to release hardware resources, close file handles, or stop background threads.

Specified by:

shutdown in interface AlgorithmProvider

Specified by:

shutdown in interface Backend
