Hi,

I have some basic questions regarding ass= ignment of input splits to Giraph workers.=A0
  1. Should each Gira= ph worker be assigned to only one split ? Can a worker sequentially process= vertices associated with its each of its splits in a superstep ?
  2. Given the same graph, would increasing the number of workers cause the = master to increase the number of splits such that each worker is assigned a= smaller chunk of the graph ?
  3. If not what is the recommended way to= make such an assignment ?=A0
thanks,
