replicate_edgelist (ResourceHandle resource_handle, src_array, dst_array, weight_array, edge_id_array, edge_type_id_array)

Replicate edges across all GPUs

Parameters

resource_handleResourceHandle

Handle to the underlying device resources needed for referencing data and running algorithms.

src_arraydevice array type, optional

Device array containing the vertex identifiers of the source of each directed edge. The order of the array corresponds to the ordering of the dst_array, where the ith item in src_array and the ith item in dst_array define the ith edge of the graph.

dst_arraydevice array type, optional

Device array containing the vertex identifiers of the destination of each directed edge. The order of the array corresponds to the ordering of the src_array, where the ith item in src_array and the ith item in dst_array define the ith edge of the graph.

weight_arraydevice array type, optional

Device array containing the weight values of each directed edge. The order of the array corresponds to the ordering of the src_array and dst_array arrays, where the ith item in weight_array is the weight value of the ith edge of the graph.

edge_id_arraydevice array type, optional

Device array containing the edge id values of each directed edge. The order of the array corresponds to the ordering of the src_array and dst_array arrays, where the ith item in edge_id_array is the id value of the ith edge of the graph.

edge_type_id_arraydevice array type, optional

Device array containing the edge type id values of each directed edge. The order of the array corresponds to the ordering of the src_array and dst_array arrays, where the ith item in edge_type_id_array is the type id value of the ith edge of the graph.

Returns

return cupy arrays of src and/or dst and/or weight and/or edge_id and/or edge_type_id.
