Sebastian, I am evaluating a directed acyclic graph (DAG). So the vertices in one superstep are not dependent on each other, only upon their predecessors.
What do you mean "execute the messaging simultaneously"? I am simply using BasicVertex.sendMsg() during BasicVertex.compute(). Is there another way to do this?
