Believe it or not, while I was struggling through this question, I sent an email to Dr.

It can be useful for rollback recovery systems on network-on-chip NOC systems. This page was last edited on 27 Februaryat A major example can be: But I can help you on that: Stack Overflow works best with JavaScript enabled.

Determining Global States of a Distributed System. Nima Soroush 6, 3 lampoet Let’s say you are running heavy computations which are split among your distributed systems.

I posted the question on cs. Can anyone explain why I am being downvoted?

Retrieved from ” https: The next morning, in the shower, I came up with the solution. The Chandy—Lamport algorithm is a snapshot algorithm that is used in distributed systems for recording a consistent global state of an asynchronous system. I don’t snaphsot the answer. If a process receives a marker after having recorded its local state, it records the state of the incoming channel from which the marker came as carrying all the messages received since it first recorded its local state.

How are Distributed Snapshot algorithms likes of Chandy Lamport implemented in alggorithm world Distributed systems? The algorithm works using marker messages.

How does this theory really translate to real world? Views Read Edit View history. Nitish Upreti 2, 7 40 When I arrived at Chandy’s office, he was waiting for me with the same solution.

Email Required, but never shown. One of the application is knowing the “Stable Lamort which is defined as a property which if present in the global state will remain so until there is an external intervention outside our distributed system.

All the other processes, upon receiving a marker, record their local state, the state of the channel from which the marker just came as empty, and send marker messages on all of their outgoing channels.

Can anyone explain, how Distributed Snapshot algorithms Example: He posed the problem to me over dinner, but we had both had too much wine to think about it right then. Jeff Dean with this question and he did send me a reply! The algorithm can be adapted so that there could be multiple snapshots occurring simultaneously.
