Hi giraph community, I'm interested in using giraph for distributed n-body simulation.
Initially, i'm interested in force directed layouts -- ie, graph drawing: http://en.wikipedia.org/wiki/Force-based_algorithms_(graph_drawing) I'm interested specifically in Dr. Andreas Noack's LinLog energy model -- which performs well w/ community detection: http://www.informatik.tu-cottbus.de/~an/GD/linlog.html I have a few examples of a serial implementation here: http://www.smarttypes.org/ The model maximizes the distance between all nodes while minimizing the distance between connected nodes. Without getting into too much detail, i'm curious if anyone has considered using giraph for force directed graph embedding (yet another name for it)? I'm also considering something like http://www.mcs.anl.gov/petsc/ or http://www.cs.cmu.edu/~scandal/alg/nbody.html -- which have fast n-body simulation implementations (Barnes-Hut + Fast Multipole). That said, i think giraph may be a good fit -- curious what the community thinks? Thanks, Timmy Wilson Cleveland, OH
