You can use it for performance testing, although it is not a great 
simulation of real graphs.  Real graphs tend to be more power law 
distributed (see https://issues.apache.org/jira/browse/GIRAPH-26).


Hope that helps,

I am using Giraph solely for performance characterization -- primarily 
comparing hardware platforms but also for Hadoop configuration

PseudoRandomVertexInputFormat, as used in the PageRank example,  to 
generate any size graphs that can then be used in the simple shortest 
path example program and thus avoiding the need to obtain actual datasets?
