Determining Global States of a Distributed System. Jeff Dean with this question and he did send me a reply! It was developed by and named after Leslie Lamport and K.

Sign up using Email and Password. When I arrived at Chandy’s office, he was waiting for me with the same solution. Views Read Edit View history. It is also used for determining the global state of the system during computation.

Chandy-Lamport Snapshot Algorithm using THRIFT’s Services

He posed the problem to me over dinner, but we had both had too much wine to think about it right then. This page was last edited on 27 Februaryat It can be useful for rollback recovery systems on network-on-chip NOC systems.

Let’s say you are running heavy computations which are split among your distributed systems. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.


Nima Soroush 6, 3 37 The Chandy—Lamport algorithm is a snapshot algorithm that is used in distributed systems for recording a consistent global state of an asynchronous system.

Can anyone explain, how Distributed Snapshot algorithms Example: But I can help you on that: The algorithm works using marker messages. Each process that wants to initiate a snapshot records its local state and sends a marker on each of its outgoing channels.

From Wikipedia, the free encyclopedia.

Nitish Upreti 2, 7 40 Chandy-Lamport are implemented in the context of modern distributed systems? Email Required, but never shown.

Chandy-Lamport algorithm – Wikipedia

Believe it or not, while I was struggling through this question, I sent an email to Dr. A major example can be: The algorithm can be adapted so that there could be multiple snapshots occurring simultaneously. 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.

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.

Stack Overflow works best with JavaScript enabled. I posted the question on cs. Post zlgorithm a guest Name. 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 does this theory really translate to real world?
