 > **Note**: As per the SYCL language semantics, separate invocations of a kernel are **independent**. This means that you can't make assumptions about memory ordering or memory dependences between kernel invocations. Make sure you use synchronization mechanisms such as the `.wait()` function or *atomic operations* to avoid race conditions. \
 If you want to guarantee sequential equivalence, you can also write your kernel with a `while(1)` loop in the kernel body instead of using a pipelined kernel. \
-In particular, a repeatedly-invoked kernel with memory dependence will result in undefined behavior in SYCL and may not function as you expect.

 For an example of a pipelined streaming kernel, see `src/stream_pipelined.cpp`.
