Sean Choi updated GIRAPH-26:
----------------------------
Attachment: GIRAPH-26-2.patch
Updated the new version of the patch.
I tried my best to change the variable names, but some are just as descriptive
as possible.
Added/Fixed some comments as well.
As for splitindex, I don't need a unique value for each working node. I need a
unique value for each split, that's why I used a split index rather than the
worker's host and port name and etc... Similarly I don't think host and port
would suffice to create different seed for each portion of the graph being
generated, as each worker can be generating more than one part of the graph.
> Improve PseudoRandomVertexInputFormat to create a more realistic synthetic
> graph (e.g. power-law distributed vertex-cardinality).

> The PageRankBenchmark class, to be a proper benchmark, should run over graphs
> which look more like data seen in the wild, and web link graphs, social
> network graphs, and text corpora (represented as a bipartite graph) all have
> power-law distributions, so benchmarking a synthetic graph which looks more
> like this would be a nice test which would stress cases of uneven
> split-distribution and bottlenecks of subclusters of the graph of heavily
> connected vertices.
