Decomposing large scale social networks is a hard problem. In this thesis we discuss and analyze the real-world problem of dividing large social graphs into smaller geographically separated pieces in a way that keeps the communication cost as small as possible from the point of view of storage, access, and replication expenses. An abstract model is formed to capture the essential properties of the communication cost problem. This model is then analyzed against other well-known problems, especially the graph partitioning problem and certain community finding problems. The problem is also solved in a way that combines graph partitioning with ideas from other areas. The end product is a practical, parallelizable algorithm suitable for d...
