Scientific Data Analysis on the Cloud


We recongize the fact our biggest stakeholder is our science communities.  This technical session focues on using the Cloud to conduct scientific data analysis.  Some of the focuse areas include

1. Technologies and solutions resuse

2. Reference architectures

3. Integration with multi-cloud environment

4. Leverage social networks and contribute back

Scientific Modeling Cloud Challenges
-Model Services Deployment: deploy each component of an application to VMs and run in isolation. Not cost effective. Can take advantage of combinations and consolidate VMs.
-Elasticity: Scale computational resources for each tier of the application
-Green computing can lead to resource contention
-Overprovisioning: too many VMs on same host
-Virtualization Overhead

NASA Earth Exchange (NEX): Early Observations on Community Engagement in the Cloud Abstract: NASA Earth Exchange (NEX) is a collaborative platform that combines state-of-the-art supercomputing, Earth system modeling, remote sensing data from NASA and other agencies, and a scientific social network to provide an environment in which users can explore and analyze large Earth science data sets, run modeling and analysis codes, collaborate on new or existing projects, and share results within and/or among communities. Through the deployment of virtualization technologies, an opportunity exists to create complete modeling and analysis environments that are customizable, “archiveable” and transferable. Allowing users to instantiate such environments on large compute infrastructures that are directly connected to data archives may significantly reduce costs and time associated with scientific efforts by alleviating users from redundantly retrieving and integrating data sets and building codes as well as provides a mechanism for sharing their work with the community. NEX is pursuing this development through OpenNEX partnership with Amazon, Inc. as well as locally through the NEX OpenSandbox, which provides private cloud environment collocated with NASA supercomputing center. This talk will focus on some of the reasons for pursuing the cloud as one of our platforms as well as our first observations on trying to generate interest and participation from a large community of geoscientists, software engineers, students and the general public. Petr Votava is a senior software engineer at NASA Ames Research Center and University Corporation at Monterey Bay. He was member of the NASA MODIS team for Terra and Aqua missions, co-PI of the Terrestrial Observation and Prediction System (TOPS) and currently he is the technical lead for the NASA Earth Exchange (NEX) science platform. His research interests include software architecture, knowledge management, data and text mining, and semantic web.
