class_docstr: This class provides interface functions for users to get the parallel context,
  such as the global rank, the local rank, the world size, etc. of each device.
  
  Note:
      The parallel_mode used in this class should be concluded in ``ParallelMode``.
      More details about ``ParallelMode`` could be found in
      `parallel_mode <https://github.com/hpcaitech/ColossalAI/blob/main/colossalai/context/parallel_mode.py>`_.
