Without the extra barrier sync towards end of barrierOR function after reading the reduction result, the caller's loop if any is going into infinite loop occasionally which is in turn randoms hangs. This doesn't seem to be an issue on non-nvidia hardware. Hence, we are conditionally adding the extra barrier sync conditionally for nvidia platform.
