framework for distributed algorithm

Question

I have to do a project where I have a dynamic graph and each node execute my algorithm to calculate the pagerank. My question is: There is a framwork that allows me to run an algorithm in the same time in each node (the algorithm is not centralized)?

Answer 1

Yes, Giraph is probably the most common example for it and can do exactly what you are looking for. However it isn't trivial to set up, there is a question from yesterday on SO about materials for Giraph: https://stackoverflow.com/questions/22817423/material-related-to-giraph/

Another example would be GraphX (http://amplab.github.io/graphx/) from spark and GraphLab (http://graphlab.org/projects/index.html), but I don't have any experience with those. However all of those frameworks enable writing code for a node and execute it for each node in a graph. They also allow you to distribute the algorithm across multiple servers for large graphs, but it isn't necessary if your graph is small enough.
