Kaile Huang, Yu Huang, Hengfeng Wei

摘要:

分布式多写入器原子寄存器是大量分布式算法的核心。在享受原子性的好处的同时,研究人员进一步探索原子寄存器的快速实现,这在数据访问延迟方面是最佳的。虽然已经证明,当读写都要求快时,多写入器原子寄存器的实现是不可能的,但当只要求写或读快时,实现是否是不可能的仍然是开放的。这项工作证明了不可能的快速写实现的基础上一系列的链参数indistiguishable执行。我们还显示了快速读取实现的必要和充分条件,通过扩展的结果在单作家的情况下。本文的工作是对分布式原子寄存器快速实现的一系列研究的总结。

英文摘要:

Distributed multi-writer atomic registers are at the heart of a large number of distributed algorithms. While enjoying the benefits of atomicity, researchers further explore fast implementations of atomic reigsters which are optimal in terms of data access latency. Though it is proved that multi-writer atomic register implementations are impossible when both read and write are required to be fast, it is still open whether implementations are impossible when only write or read is required to be fast. This work proves the impossibility of fast write implementations based on a series of chain arguments among indistiguishable executions. We also show the necessary and sufficient condition for fast read implementations by extending the results in the single-writer case. This work concludes a series of studies on fast implementations of distributed atomic registers.
