A technique includes performing graph inference in a graph inference engine that includes multiple processing nodes to determine assignments for vertices of a graph. Performing the graph inference includes controlling remote memory accesses within the engine, including storing first data in a local memory of the first processing node, where the first data represents at least assignments for a plurality of vertices of the graph; in the first processing node, determining updates for the assignments for a subset of the plurality of vertices of a partition of the graph assigned to the first processing node and modifying the first data based on the updates; and communicating the updates to at least one other processing node of the multiple processing nodes, where at least one other partition of the graph is assigned to the other processing node(s).

An article comprising a non-transitory computer readable storage medium to store instructions that when executed by at least one processor core associated with a processing node cause the at least one processor core to: read a graph partition table from a local memory of the processing node, the graph partition table describing a partition of the graph assigned to the processing node; read a local copy of a vertex table from the local memory, the local copy of the vertex table describing vertices of the graph; perform graph inference to update assignments of vertices contained with the partition of the graph assigned to the processing node; write the updated assignments to the local copy of the vertex table; and write the updated assignments to a copy of the vertex table stored in a local memory of at least one other processing node. 11. The article of claim 10, the storage medium storing instructions that when executed by the at least one processor core cause the at least one processor core to: accumulate the updates of the assignments; compare a number of the accumulated updates to a threshold; and write the updated assignments to the copy of the vertex table stored in the at least one other processing node in response to a comparison of the number to a predetermined threshold. 12.
