This will pause all workers until at least ``world_size`` workers respond. This uses a fast incrementing index to assign waiting ranks and a success flag set by the last worker. Time complexity: O(1) per worker, O(N) globally. Optionally, passing rank will enable tracing of missing ranks on timeouts. `rank_tracing_decoder` lambda arg can be used to convert rank data into a more meaninful information at an app level (e.g. hostname). Note: Since the data is not removed from the store, the barrier can be used once per unique ``key_prefix``.
