Function Documentation

CkReductionMsg* imagePollCombineReducer	(	int	nMsg,
		CkReductionMsg **	msgs
	)

Called by the reduction manager to combine all the source images received on one processor.

This function adds all the image on one processor to one list of non-overlapping images.

Then the result is reduced onto processor zero in function vizPollReductionHandler()
