Description

its a bit unclear from the documentation of what exactly is the mmauniversalop, does it use tensor cores or the cuda cores itself?

mma_op = cute.nvgpu.MmaUniversalOp(cutlass.Float32)
    mma_atoms_layout = cute.make_layout((mma_m, mma_n, 1), stride=(mma_n, 1, 0))
    tiled_mma = cute.make_tiled_mma(
        mma_op,
        atom_layout_mnk=mma_atoms_layout,
    )
