Description
I'm learning the tutorial about sgemm_1.cu here: https://github.com/NVIDIA/cutlass/blob/v3.5.0/examples/cute/tutorial/sgemm_1.cu
My question is that:
How can we know the output of C?
I see in both cases, the gemm_nt and gemm_tn, the C matrix is always with stide (1, M).
Is that the requirement of cute? Or we can also define it as (M, 1)?
I'm quite confused about this.
Another question, the N, T is based on the condition that a tensor is always column major with out transpose? right?

Research direction
Start with examples/cute/tutorial/sgemm_1.cu, focusing on the gemm_nt and gemm_tn examples and their C tensor strides. Trace how the tutorial defines the tensor layouts and documents N/T, then clarify how the output layout is determined and whether an alternative layout is supported. Done means the tutorial or its surrounding documentation answers both questions directly.
