input_graph_degree,output_graph_degree, andgraph_sizevariables touint64_t.Before the PR, they've been
uint32_t, and the product of them could overflow. This would lead tocudaMemsetAsyncnot filling in a large fraction of the graph.It's not known whether this bug has surfaced for anyone until now, but it's better to be safe than sorry.
