sourceIndices | Input, source vertex’s out members |
sourceWeights | Input, weights of the source vertex’s out members |
topK | Input, the output similarity buffer length |
gr | Input, CSR graph of IDs’ type of uint32_t and weights’ type of float |
resultID | Output, the topK highest similarity IDs |
similarity | Output, similarity values corresponding to theirs IDs |
