Method Detail

initialize

void initialize(ADag dag,
                PegasusBag bag)
                throws ClustererException

Initializes the Clusterer impelementation

Parameters:

dag - the workflow that is being clustered.

bag - the bag of objects that is useful for initialization.

Throws:

ClustererException - in case of error.

determineClusters

void determineClusters(Partition partition)
                       throws ClustererException

Determine the clusters for a partition.

Parameters:

partition - the partition for which the clusters need to be determined.

Throws:

ClustererException - in case of error.

parents

void parents(String partitionID,
             List parents)
             throws ClustererException

Associates the relations between the partitions with the corresponding relations between the clustered jobs that are created for each Partition.

Parameters:

partitionID - the id of a partition.

parents - the list of String objects that contain the id's of the parents of the partition.

Throws:

ClustererException - in case of error.

getClusteredDAG

ADag getClusteredDAG()
                     throws ClustererException

Returns the clustered workflow.

Returns:

the ADag object corresponding to the clustered workflow.

Throws:

ClustererException - in case of error.
