Views Read Edit View history. When I arrived at Chandy’s office, he was waiting for me with the same solution.

One of the application is knowing the “Stable Property” 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.

Retrieved from ” https: Each process that wants to initiate a snapshot records its local state and sends a marker on each of its outgoing channels. It was developed by and named after Leslie Lamport and K. The algorithm can be adapted so that there could be multiple snapshots occurring simultaneously.

But I can help you on that: By using this site, you agree to the Terms of Use and Privacy Policy. Can anyone explain why I am being downvoted? The algorithm works using marker messages. Ishani Gupta 57 9. 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.

I posted the question on cs. Stack Overflow works best with JavaScript enabled.

It is also used for determining the global state of the system during computation. The next morning, in the shower, I came up with the solution.

How are Distributed Snapshot algorithms likes of Chandy Lamport implemented in real world Distributed systems?

Chandy-Lamport algorithm

Let’s say you are running heavy computations which are split among your distributed systems. Believe it or not, while I was struggling through this question, Snapshott sent an email to Dr. Sign up using Facebook. Determining Global States of a Distributed System.

Nima Soroush 6, 3 37 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.

It can be useful for rollback recovery systems on network-on-chip NOC systems. Nitish Upreti 2, 7 40 The Chandy—Lamport algorithm is a snapshot algorithm that is used in distributed systems for recording a consistent global state of an asynchronous system.

Chandy-Lamport are implemented in the context of modern distributed systems? I don’t know the answer.

He posed the problem to me over dinner, but we had both had too much wine to think about it right then.
