Report Introduction:
There is significant interest nowadays in developing the frameworks for parallelizing the bet365 live casino review of large graphs such as social networks, Web graphs, etc. The work has been proposed to parallelize the graph bet365 live casino review on clusters (distributed memory), multicore machines (shared memory) and GPU devices. Most existing research on GPU-based graph bet365 live casino review employs the vertex-centric bet365 live casino review model and the Compressed Sparse Row (CSR) form to store and process a graph. However, they suffer from irregular memory access and load imbalance in GPU, which hampers the full exploit of GPU performance. In this talk, I will present WolfGraph, a GPU-based graph bet365 live casino review framework that overcomes the above problems. WolfGraph adopts the edge-centric bet365 live casino review, which iterates over the edges rather than vertices. The data structure and graph partition in WolfGraph are carefully crafted so as to minimize the graph pre-bet365 live casino review and allow the fully coalesced memory access. WolfGraph fully utilizes the GPU power by bet365 live casino review all edges in parallel. We also developed a new method, called Concatenated Edge List (CEL) to process a graph that is bigger than the global memory of GPU. WolfGraph allows the users to define their own graph-bet365 live casino review methods and plug them into the WolfGraph framework.
