What does "sliced1x4_nn" mean in matmul?

Hi! I am learning matmul and trying to perform cutlass and cublas. I see this in nsight compute:

I am calculating 3072 * 3072 3072 * 64 => 3072 * 64 matmul, and see this in nsight: volta_sgemm_64x32_sliced1x4_nn(1, 96, 1)x(256, 1, 1). Do you have any idea what sliced1x4 means? I only see this 1x4 in cutlass…

Also, what do you think nn is?

Thank you!!!
