Chandy lamport算法实现
The Chandy–Lamport algorithm is a snapshot algorithm that is used in distributed systems for recording a consistent global state of an asynchronous system. It was developed by and named after Leslie Lamport and K. Mani Chandy. See more According to Leslie Lamport's website, “The distributed snapshot algorithm described here came about when I visited Chandy, who was then at the University of Texas in Austin. He posed the problem to me over dinner, but … See more The assumptions of the algorithm are as follows: • There are no failures and all messages arrive intact and … See more The Chandy–Lamport algorithm works like this: 1. The observer process (the process taking a snapshot): 2.
