CUB offers an implementation of sparse matrix-vector multiplication. But so does cuSPARSE. We should investigate whether

  • cuSPARSE offers at least the same functionality as CUB
  • and reaches at least the same performance.

If both are the case, we should deprecate cub::DeviceSpmv with a note that users should switch to cuSPARSE and eventually remove it.
