C. Panel Theme

Nowadays, Cloud is not a debate of a future technology, but it simply exists. It is initiated based on years of vision, research and development. The Cloud now penetrates into our daily life and it provides resource from computation and hardware, to software and services.

During this rage on Cloud, the industry has gained huge amount of experiences even in a short period of time. They face technical problems that make them headache every morning; new and outrageous customer requirements that can hardly be conceived in advance; hesitation on long term future directions and emerging business competitions every now and then.

Do we get everything right? Are there any technical difficulties that the research community should get involved, both for the daily headaches and in the long term perspect? In this panel we primarily invite industry practitioners to discuss their joy and pain in their experiences of Cloud. We also invite a few academic researchers to discuss share their findings in the past.

All are welcome to join our panel discussion.

Title: Distributed Framework for Iterative Computations on Massive Datasets
Prof. Lixin Gao
University of Massachusetts

Abstract: Iterative algorithms are pervasive in many applications such as search engine algorithms, machine learning, and recommendation systems. These applications typically involve a dataset of massive scale. Fast iterative computations of the massive datasets are essential for these applications. This is particular important for on-line query such as keyword based search query. In this talk, we present an overview of MapReduce framework, and propose two frameworks, iMapReduce and pMapReduce, that enable fast iterative computations. By providing the support of iterative computations and prioritized execution, we can ensure faster convergence of the iterative process. Both iMapReduce and pMapReduce preserve the MapReduce distributed computing framework and is particularly efficient for online queries such as top-k queries. We implement iMapReduce and pMapReduce based on Apache Hadoop and evaluate its performance. Our evaluation results show that pMapReduce can reduce the computation time by two orders of magnitude comparing to that achieved with MapReduce. At the end of the talk, I will provide an overview of on-going projects in my research group.
