Methods and systems for distributed computation of graph data permit edge collection and vertex collection, each to be partitioned among a plurality of computational units. In one embodiment, the methods employ a two-phase computational cycle, which is repeated until the computation is complete. In a first phase, processing units process each active edge and vertex by doing the following: reading their current attribute values, executing programmed computational functions, updating edge attributes and sending data messages to vertices. In a second phase, each vertex update processor processes each of its active vertices by doing the following: reading its current attribute values and received data messages, executing a programmed computational function, and updating the vertex's attribute values. |
