After make, run the instruction. / bfs-sync -- input. / edge_ 875713.el

The tips are as follows: Reading the input graph from the following file:

    ./edge_875713.el
    Done reading.
    Number of nodes = 875713
    Number of edges = 9238952
    Graph Reading finished in 1.80066 (s).
    GPUassert: out of memory subgraph.cu 40

Why is it out of memory

Please send me the graph file.

Sorry, I didn't reply you in time. The problem has been solved. I modified the code in subgraph.cu line 24 from max_partition_size = 0.9 * (dev.totalGlobalMem - 84num_nodes) / sizeof(E); to max_partition_size = 0.1 * (dev.totalGlobalMem - 842*num_nodes) / sizeof(E); I consider whether the original code will inevitably cause problems, regardless of the size of the graph. But I don't know whether such modification will affect the performance of the system. Please advise me.
