cublasStatus
cublasGetVectorAsync( int n, int elemSize, const void *x, int incx,
void *y, int incy, cudaStream_t stream)

cublasGetVectorAsync has the same functionnality as cublasGetVector
but the transfer is done asynchronously within the CUDA stream passed
in parameter.

Return Values
-------------
CUBLAS_STATUS_NOT_INITIALIZED  if CUBLAS library not been initialized
CUBLAS_STATUS_INVALID_VALUE    if incx, incy, or elemSize <= 0
CUBLAS_STATUS_MAPPING_ERROR    if an error occurred accessing GPU memory
CUBLAS_STATUS_SUCCESS          if the operation completed successfully
