Calling MG Louvain is currently crashing with an uncaught cudaErrorInvalidValue exception (see screenshot).
This is occurring with both RMAT-generated and existing hibench CSV file inputs.

Are we symmetrizing R-mat graph? AFAIK, Louvain expects undirected graph (so the input edge list should be symmetric).
