Description copied from interface: Collector

get the collected valued

Specified by:

get in interface Collector

Returns:

get the default output

public boolean allReduce(byte[] content)

Specified by:

allReduce in class AllReduceCompute<byte[]>

getCollectibleNames

public IONames getCollectibleNames()

Description copied from interface: Collector

This method should return a set of collectible names, that can be collected from this collector. These names will be used by task plan builder to cross validate parallelism between two task graphs.

If Collector C of task graph TG1 collects variable "var1" and C's parallelism is n, If Receptor R of task graph TG2 is interested in receiving "var1", R's parallelism should be equal to n and, R should have the same distribution as C among the workers.

Specified by:

getCollectibleNames in interface Collector

Returns:

set of names of collectbles
