Consider replacing sycl::<...>::barrier() with sycl::<...>::barrier(sycl::access::fence_space::local_space) for better performance if there is no access to global memory.
Detailed Help
The function sycl::<...>::barrier() ensures correct memory access ordering in the global and local address space. If the kernel function has no memory accesses in the global memory, it is safe to replace sycl::<...>::barrier() with sycl::<...>::barrier(sycl::access::fence_space::local_space) for better performance.
Suggestions to Fix
Replace sycl::<...>::barrier() with sycl::<...>::barrier(sycl::access::fence_space::local_space).
