Hi, I recently started playing with Giraph and I have a few questions.
1. I'm writing a simple spreading activation algorithm which would be run many times over the same graph with different initial vertices activated. Doing this as separate jobs in which a potentially large graph is loaded each time will be slow. Is there a way to run multiple BSP runs over the same loaded graph? 2. I might want to normalise the vertex values at the end of a superstep. I assume I can use an aggregator to get the sum of the values but I'm not sure where can I update all vertex values before the next superstep? 3. On a smaller trivial point: Running within a LocalRunner for debugging I need to delete the local zookeeper state created in _bsp* folders otherwise the next run does nothing as its assumes its the same state and just finishes straight away. What is the local id that is being used to determine the job state in Zookeeper and is it possible to set this so each LocalRunner job run is different? Thanks, Clive
