There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: Going Beyond Scalability to Build Resource-Efficient Data-Intensive Applications
Abstract:
It is now common for individual applications such as search engines and social networks to serve a billion users. Enabling that growth has been a relentless pursuit of scalability, in hardware and software that has culminated in expensive and power-hungry data centers. Yet the delivered performance of these systems has lagged behind their potential capability by an order of magnitude or more.
In this talk, I will describe two projects focused on improving data center resource efficiency. The first is a MapReduce implementation built upon an IO-optimized distributed sorting system called TritonSort. When applied to the 100 TB GraySort benchmark, it improved upon the absolute performance of the previous world record holder by 25%, using 66 times fewer servers. As a result, it has attained the 100 TB JouleSort record for energy-efficient data processing. The second project focuses on the design of the underlying data center network. Existing scalable data center network designs promise full bisection bandwidth between all servers, though with significant cost, complexity, and power consumption. Instead, we propose a hybrid electrical/optical switch architecture that can deliver a nearly 3x reduction in cost and 6x reduction in power consumption relative to the state of the art.
