All Implemented Interfaces:

net.ssehub.easy.instantiation.core.model.vilTypes.IVilType

public class SubTopologyScalingHelper
extends Object
implements net.ssehub.easy.instantiation.core.model.vilTypes.IVilType

An instantiator for accessing the expected sub-topology scaling of manually implemented sub-topologies. The request is passed throught to the scalability descriptor of the implementing topology.

Method Details

getSubTopologyScaling

public static net.ssehub.easy.instantiation.core.model.vilTypes.Map<String,Integer> getSubTopologyScaling(String pipeline,
 String algorithm,
 double factor,
 boolean executors)

Returns the sub-topology scaling for a given algorithm, i.e., if the algorithm is implemented by a (manual) sub-topology.

Parameters:

pipeline - the pipeline name

algorithm - the algorithm name

factor - the scaling factor

executors - scale the executors or the tasks

Returns:

the expected scaling (no scaling if empty)

getSubTopologyScaling

public static net.ssehub.easy.instantiation.core.model.vilTypes.Map<String,Integer> getSubTopologyScaling(String pipeline,
 String algorithm,
 int oldExecutors,
 int newExecutors,
 boolean diffs)

Returns the sub-topology scaling for a given algorithm, i.e., if the algorithm is implemented by a (manual) sub-topology.

Parameters:

pipeline - the pipeline name

algorithm - the algorithm name

oldExecutors - the (actual) number of overall executors

newExecutors - the new number of overall executors

diffs - return the differences (true) or the absolute values (false)

Returns:

the expected scaling (no scaling if empty)
