Hi, We are trying to implement a BSP model in Spark with the help of GraphX. One thing I encountered is a Pregel operator in Graph class. But what I fail to understand is how the Master and Worker needs to be assigned (BSP), and how barrier synchronization would happen. The pregel operator provides a way to define a vertex program, but nothing is mentioned about the barrier synchronization. Any help in this regard is truly appreciated. Many Thanks, Ghousia.
