Why databank read is non zero, even i do not use any shared memory?

[oicuoicu0619]

Hi , i am profiling a really simple kernel and there is no shared memory use.

__global__ void stride(const float *A, float *B){
    int idx = threadIdx.x+blockDim.x*blockIdx.x;
    B[idx]= A[idx*Stride];
}

In memory section of nsight compute, why there are some shared memory use ?

l1tex__data_pipe_lsu_wavefronts_mem_shared is 65536 .
Thanks for the help!
