    Description

      At now, our FileBlock cannot fully exploit the bandwidth of disk when read data sequentially (One-to-One communication pattern).
      To improve this, we can read all data sequentially at first, and decode it lazily.
      Also, we assume that the parallelism of all One-to-One read and write is 1 but it is not true. We need to fix this.
