A partition-based hybrid hierarchical graph computation approach, called H2Pregel is proposed to address the redundant supersteps and inefficient computation problems due to low access locality. The H2Pregel preprocesses the input graph through a distributed recode algorithm to ensure the continuity and sequence of vertex ids, then employs a hybrid approach to combine the advantages of both synchronous and asynchronous models, and hierarchically computes the high proportion of interior messages generated by high quality partition algorithms. Moreover, H2Pregel leverages configurable parallel threads to accelerate local computation by “sub-supersteps”, and employs an exterior messages stealing optimization to avoid extra communication overheads between tasks. We implemented H2Pregel on Giraph, a classic open source system based on Pregel. The evaluation results on large-scale graphs show that, compared with Pregel in three partition algorithms, H2Pregel can achieve average speedups by 1.12–4.52 times and decrease average communication messages by 23.5%-55.5%, and average supersteps by 15.8%-82.0%. |
