[Nets-seminars] TODAY @ 3PM Faculty Candidate Talk: Wyatt Lloyd (Princeton)

[Patel, Dee]

Dear Academic and Research Staff, and Research Students



We recently advertised for Faculty Position in Networking and Systems. One of the shortlisted candidates will be coming to visit the department and give a seminar on Monday 18th March 2013.  All academic staff are strongly encouraged to attend these talks.



Seminars typically last an hour and fifteen minutes including questions.



As these seminars are part of a recruitment process, please do not forward details to mailing lists or to anyone outside UCL, as candidates rarely want it to be widely known that they have applied to UCL.  If in doubt about forwarding, please ask me first.



Kind Regards

Dee Patel

TITLE:

Stronger Consistency and Semantics for Geo-Replicated Storage



ABSTRACT:

Geo-replicated storage systems provide the backend for massive-scale websites such as Google and Facebook. These storage systems seek to provide an always-on experience where every operation completes quickly because of a widely demonstrated link between page load times, user engagement, and revenue. We term systems that provide an always-on experience and can handle data at the required scale "ALPS" systems because they provide four key properties: Availability, Low latency, Partition tolerance, and Scalability.

Previous ALPS systems made large usability sacrifices in pursuit of their scale and performance goals. They settled for eventually consistent replication between datacenters and inconsistent batch operations within them. My research shows that these sacrifices are not fundamental.



In this talk, I will present the first ALPS system to provide consistency that is stronger than eventual. Specifically, I will show how to provide causal consistency for data stored in multiple datacenters, each of which spreads the data across many servers. Then, I will show how to strengthen the semantics of that system with a richer data model as well as read-only and write-only transactions.



BIO:

Wyatt Lloyd is a Ph.D. candidate in Computer Science at Princeton University.  His research interests include the distributed systems and networking problems that underlie the architecture of large-scale websites, cloud computing, and big data.  He received his masters degree in Computer Science from Princeton University, and a bachelors degree in Computer Science from Penn State University.
