Description
Could you explain how TMA works in CUTLASS? For example, when writing from the shared memory Tensor sS to the global memory Tensor gD, it seems that the data is written sequentially, i.e., sS[i] directly maps to gD[i]. Is this the correct behavior?

Research direction
Start by tracing the CUTLASS TMA operation for the shared-memory tensor sS and global-memory tensor gD. A useful response should explain whether sS[i] maps directly to gD[i] and describe the addressing or layout behavior that determines the write order.
