@whitneywhtsang what is the ticket # for enabling split barrier?

There was a functional failure when enabling split barrier, it is fixed in https://github.com/intel/intel-xpu-backend-for-triton/pull/1708. As commented in https://github.com/intel/intel-xpu-backend-for-triton/pull/1708#issuecomment-2253097323, there is no performance gain in GEMM geomean, so it is not enabled.
