The invention relates to the field of graph data processing, discloses a coarse-grained graph data asynchronous iterative updating method, and realizes asynchronous message communication between a point partition data set and an edge partition data set by adopting a remote procedure call protocol. According to the coarse-grained graph data asynchronous iterative updating method, a point partitiondata set and an edge partition data set in large-scale graph data are packaged into a remote procedure call protocol message loop body, asynchronous message communication is achieved, and I/O processing cost caused by frequent access to an external memory is avoided.
