WebA distributed snapshot algorithm captures a consistent global state of a distributed system. A global state can be described by a cut that indicates the time at which each process \checkpoints" its local state and messages. In the case of a consistent cut C (Fig 14.1), if a message crosses C, its \send" should be before C and its \receive ... WebDistributed Systems Time and Global State IntroductionIn this part of the course we will cover: I Why time is such an issue for distributed computing I The problem of maintaining a global state I Consequences of these two main ideas I Methods to get around these problems.
