Abstract

The volume of real-world data in many domains is growing at an unprecedented rate. To address such big data challenges, I have been working on several research projects for designing and building scalable techniques and frameworks. This presentation will focus specifically on two distributed frameworks, one for scalable assembly of third-generation genome sequences and the other for scalable graph data processing using a NoSQL store.

I will first present a distributed genome assembly framework that can assemble large-scale third-generation sequence datasets using thousands of cores, resulting in faster assembly. The framework is built on the map-reduce computation model. I will then describe a distributed graph processing framework for iterative algorithms. The framework utilizes a disk-based NoSQL system to process big graph data in a scalable manner while improving the overall performance through several optimization techniques.
