 @brief  DDS processing topology using multiplied data publisher and one data sink

 This topology definition is going to be used with DDS. It defines multiple data
 publishers on different nodes and one data sink receiving the data. The DDS
 host configuration file should define 1 agent per node in order to make sure that
 publisher tasks are distributed to the nodes.

 The HLT FilePublisher component needs a configuration file with name
 /tmp/tpc-cluster-publisher.conf on the publisher nodes
