Global state and snapshot recording algorithm
Did you know?
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. Web4 Global state and snapshot recording algorithms 4.2 System model and definitions 4.2.1 System model The system consists of a collection of n processes,p 1 ,p 2, ,p n, that are connected by channels. There is no globally shared memory and processes communicate solely by passing messages. There is no physical global clock in the system.
