Recently, Research using GPU has been conducted to process large graph data. Since large graphs cannot be efficiently processed by GPUs with limited memory, they must be divided into multiple subgraphs. In this paper, we propose a SSSP graph algorithm processing scheme on GPU through efficient subgraph partitioning method. The large graph partitioning method determines how to efficiently divide the large graph into subgraphs that can be processed by the GPU. The value-driven subgraph scheduling method quantifies the value of subgraphs to estimate the computational volume of subgraphs. It reduces the duplicate transmission of data, by increasing the transmission rate of active edges to reduce HOST-GPU transmission time. We conduct various performance evaluations in order to show the superiority of the proposed scheme. |
