Global Memory and CUDA streams

I'm working on CUDA and I have a doubt about global memory and streams CUDA.

Let:

__device__ float Aux[32];
__global__ void kernel1(...) {
    [...]
    Aux[threadIdx.y] = 0;
    [...]
}

So, if I run this kernel on different streams GPU. Is Aux the same for all streams? or there is a Aux variable for all streams being Aux global variable? I can't find that information in the guide cuda.

Thanks in advance.

It's the same for all streams.

Streams control the (partial) order in which kernels are executed. They do not create new namespaces.
