The Network is Reliable is an excellent article which attempts to formalise the discussion on real world failures for distributed systems. There is currently great debate on whether the assumption that network partitions are rare is too strong or too weak, for modern networks. Much of the data which we could use to answer this question is not published, […]
Here is the draft of my EuroSys doctoral workshop workshop poster. I would appreciate any feedback on the poster, I hope to sent it to the printers in 3/4 hours.
I’m looking forward to sharing my thoughts on consensus for the edge network with the SRG today, abstract below Many projects in the SRG at the moment (HAT, UCN, contacts app, MirageOS for ARM, Jitsu, databox, signposts) are trying to give individuals an viable alternative to 3rd party centralised services and put them back in […]
Tangaroa, is a Byzantine tolerant Raft implementation in Haskell, developed by Christopher Copeland and Hongxia Zhong for a Distributed Systems class at Stanford. The authors apply many of the approaches in PBFT to Raft, allowing for the Byzantine failure of nodes. My interest in this work is how can you stop unnecessary leader elections in Raft algorithm using more […]
Here is a draft copy of the A1 poster I’ll be presenting at the 2nd Annual Oxbridge Women in Computer Science Conference in Oxford. The poster abstract is in a previous post. Any feedback would be greatly appreciated. version 1 (9:20 11/3) version 2 (10:50 11/3) now with left alignment of text on the left and right alignment […]
I am incredibly excited to announce that Raft Refloated will be featured in The Morning Paper, by Adrian, as part of a series of 10 posts on distributed consensus. Last month, the morning paper also featured our work on the Databox. Will the raft paper sink or swin? Let’s wait and see.
The January edition of the Operating System Review is now out, look out for “Raft Refloated: Do We Have Consensus?”. Also available without dead trees.
The January edition of SIGOPS Operating Systems Review is out now and thus is the aptly named “Raft Refloated: Do We Have Consensus?”. This is my first journal paper and I’m really existed to see what the community makes of it. Title: Raft Refloated: Do We Have Consensus? Authors: Heidi Howard, Malte Schwarzkopf, Anil Madhavapeddy and […]
My undergraduate dissertation has made it to the front page of Hackernews with 80 points, https://news.ycombinator.com/item?id=8736868.
“ARC: Analysis of Raft Consensus” is now available online as a UCAM technical report. http://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-857.pdf Abstract The Paxos algorithm, despite being synonymous with distributed consensus for a decade, is famously difficult to reason about and implement due to its non-intuitive approach and underspecification. In response, this project implemented and evaluated a framework for constructing fault-tolerant applications, […]
