Hi @rajagond, thanks for the detailed report. I've confirmed the problem with -B 8:
input_tensor_2d: (16384, 24576), device id: <CUDA Device 0>
input_tensor_3d: (8, 2048, 24576), device id: <CUDA Device 0>
weights: (24576, 12288), device id: <CUDA Device 0>
output_2d: (16384, 12288), device id: <CUDA Device 0>
output_3d: (8, 2048, 12288), device id: <CUDA Device 0>
CuPy MatMul Time (2d): 51.69049 ms
CuPy MatMul Time (3d): 790.34568 ms
CuPy MatMul Time (% diff): 1429.00%
matmul has a fast path for 2d case (which just uses cupy.dot), and looks there is a room for improvement for 3d case.
