摘要: A failure detector is a distributed oracle that provides processes in system with hints about failures. The notion of weakest captures the exact amount synchrony needed for solving given computing problem.In this paper, we determine k-set agreement among n (n > k) using reads and writes shared memory, regardless assumptions on when where failures might occur. This derived directly from impossibility wait-free k + 1-process agreement. Our approach can be viewed as an extension asynchronous BG-simulation technique to partially synchronous systems.
