reasoning
**Considering block and warp dimensions** I'm thinking about mapping one block per sample with 256 groups and computing in 256 warps. But wait, could that lead to too many threads? If I use one block with 256 threads to handle one row, it seems like each warp would handle one group. I want to ensure I'm optimizing the thread count effectively, so I need to explore how those dimensions will play out in practice. There’s definitely some complexity here!
