In most graph processing engines, when the partitioning starts, the majority of the graph is already known. A possible drawback stems from its reduced strong scalability, as the iteration count to converge for a given problem tends to grow with the number of processors used. It is critical to develop a general purpose platform for graph processing. For instance, optimizing the cut size for free group sizes puts all vertices in the same community. Linear Algebra Appl. Trans. e graph partitioning algorithms of distributed graph databases have to make per-transaction, online decision rapidly, whereas the ones for graph processing engines do not.

: Direct solutions of sparse network equations by optimally ordered triangular factorization. Our algorithm is partitioning in nature. Cost of Graph Partitioning • Many possible partitionings to search: • n choose n/2 ~ sqrt(2n/pi)*2n bisection possibilities • Choosing optimal partitioning is NP-complete – Only known exact algorithms have cost that is exponential in the number of nodes in the graph, n • We need good heuristics-based algorithms!
