Specifically, the word "cash" in your post does not make sense in this context.
Please restate your question.
Each subscriber* application has at least one DataReader on a Topic that it is interested in. Each subscribing application will process the incoming data. If the application has multple DataReaders on a Topic, then it will process the incoming data once per DataReader.
* Note the semantic difference between "subscriber" and "Subscriber": A "Subscriber" is a DDS entity. A "subscriber" is used in the general sense, to indicate an application that listens to a Topic. I point this out because you aren't using capital letters, so I can't be sure which you mean, a Subscriber or a subscriber.
