Research direction

No file or test path is provided. Locate the Comm group implementations for HALO_EXCHANGE, HALO_EXCHANGE_FUSED, HALO_PACKING, HALO_PACKING_FUSED, and HALO_SENDRECV, then review how their existing variants are organized. Done means each listed kernel has both a Base_SYCL and a RAJA_SYCL variant.
