Description
`cub::DeviceTransform` jumps through hoops to handle unaligned inputs, especially in the `memcpy_async` (LDGSTS) and `ublkcp` kernel. If the user gave us a compile-time guarantee that all buffers are aligned, the kernel could be simplified.
Let's investigate the performance impact of such a guarantee.
