Conference on Data Analysis (CoDA) 2014

CSMD had a strong presence at the CoDA conference, which is a new biennial conference series for "Exploring Data-Focused Research Across the Department of Energy" that takes place in Santa Fe, NM. This year's conference was March 5-7. The invited program featured sessions on data-intensive applied science, uncertainty quantification, national security, big data and exascale computing, energy and the environment, and signature discovery. ORNL participation included all aspects of the conference:

George Ostrouchov (CSMD/SDG), Organizing Committee and Poster
Kate Evans (CSMD/CES), Plenary talk
Yuan Tian (CSMD/SDG), Invited talk
Cynthia Gu (CSMD/SDG), Poster
Damian M. Maddalena (CSMD/CES), Poster
Sarah Powers (CSMD/CSR), Poster

The conference had a single track of plenary and invited talks and a poster session. Many have noted that this was likely the best conference of the year due to its great opportunities for interaction between attendees. On the fun side, the conference banquet talk was by Amanda Cox, a Graphics Editor at the New York Times, who recently won the American Statistical Association's Excellence in Statistical Reporting Award. Her talk was on "Sketching the News: Data Graphics at the New York Times." As a side note, the 2012 conference banquet talk was "Blowing Stuff Up for Science: Explosives Experiments with the Myth Busters." These will be hard to surpass at the next meeting in 2016.

Eclipse Foundation

Jay Jay Billings

ORNL joined the Eclipse Foundation, which manages both an open source community and the development of the popular Eclipse Integrated Development Environment. The effort to join the Foundation was led by Jay Jay Billings of the Computer Science Research group to address several pressing issues for the NEAMS Integrated Computational Environment (NiCE).

Membership in the Foundation includes many benefits and applies site-wide to all UT-Battelle employees and subcontractors (including ORAU/ORISE post-graduates). In addition to providing access to a user base of more than nine million users for Eclipse projects, the Eclipse Foundation also provides marketing and advertising support, intellectual property-friendly contributor agreements to help with contributions to projects from third-party developers and access to hundreds of skilled developers from some of the biggest (and smallest!) companies in the tech sector. The process of proposing new projects is also streamlined for members since the necessary agreements are already in place.

Membership also allows ORNL to participate in the new Eclipse Science Working Group (SWG). The SWG is focused on creating new, science-focused Eclipse projects with completely new code bases or contributions from Foundation members in a technology-agnostic setting (read "not only Java projects"). The SWG also acts as a support community related to scientific activities projects with Eclipse.

Jay pursued membership in the Foundation primarily because of growing contributions from external collaborators to NiCE. Each contributing organization has its own set of policies related to open source software, intellectual property rights and code contributions, so the easiest and safest route was to creating a new project with a third party software Foundation. Since NiCE is based on the Eclipse Rich Client Platform and the NiCE team has been involved with the community for a number of years, the Eclipse Foundation was the obvious choice. A proposal to create the Eclipse Integrated Computational Environment, with NiCE as the initial contribution, is currently under review.

John Cobb served on the Steering committee for the NSF funded workshop "ADVANCED REGIONAL & STATE NETWORKS (ARNS): ENVISIONING THE FUTURE AS CRITICAL PARTNERS IN DATA-DRIVEN SCIENCE" Held at Internet2 In Washington DC April 18-19, 2013. The invitation-only workshop was envisioned as assembling a small group of thought-leaders to address issues on building awareness and preparedness of the impact of Big data among both the group of advanced regional network providers and the scientific data communities.

John Cobb presented one of the abbreviated Keynote talks at the "ADVANCED REGIONAL & STATE NETWORKS (ARNS): ENVISIONING THE FUTURE AS CRITICAL PARTNERS IN DATA-DRIVEN SCIENCE" workshop held at Internet2 in Washington DC April 18-19, 2013. John's talk was titled "Data Driven Science Requires Advanced, Distributed Analysis" and is available on the workshop site at https://www.mcnc.org/sites/default/files/Cobb_ARN2_v02.pdf.

John Cobb participated in the NEES governing board meeting on March 18, 2013 as a member of The George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) governing Board.

John Cobb has been appointed the the research advisory board of the DMPTool project. The DMPtool is an online resource to assist in the development and preparation of data management plans for research projects. It is a guided process document that contains man of the data management requirements for many federal agencies and academic and research institutions. It also used a federated identity system (InCommon) in order to facilitate multi-institutional and multi-agency projects. The DMPTool project is housed at the California Digital Library but the project is a collaboration of eight different universities, research institutions, and digital data projects. The Research advisory board with provide high-level guidance and feedback to the DMPTool on directions and development in application functionality, DMPTool content, community engagement, and the researcher value proposition.

Successful workshop on Big Data and High Performance Computing
hosted by ORNL in Jekyll Island Georgia

SOS is an invitation-only 2 1/2 day meeting held each year by Sandia labs, Oak Ridge National lab, and Swiss Technical institute.
This year it was hosted by ORNL in Jekyll Island Georgia on March 25-28, 2013.

The theme this year was "The intersection of High Performance Computing and Big Data". There were 40 speakers and panelists
from around the world representing views from industry, academia, and national laboratories. The first day focused on the gaps
between big computing and big data and the challenges of turning science data into knowledge. On the second day the talks and panels focused on where HPC and big data intersect and the state of big-data analysis software. The morning of the third day focused on the politics of big data including the issues of data ownership.

Findings of the meeting include the fact that large experimental facilities such as CERNs Large Hadron Collider, and the new
telescopes coming online already generate prodigious amounts of scientific data. The volume and speed that data is generated
requires that the data be analyzed on the fly and only a tiny fraction be kept. The amount kept still amounts to many petabytes.
The attendees stressed how important provenance is to the use of the archived data by other researchers around the world. The majority of today's scientific data is only of value to the original researcher, because the data lacks the meta-data required for others to use it. The talks and panels clearly showed the intersection of high performance computing and big data. They also showed that the converse is not necessarily true, i.e. big data (as defined by Google and Amazon) does not require high performance computing. These vendors and their customers are able to get their work done on large, distributed networks of independent PCs. The meeting was filled with lively discussion, and provocative questions.

For those wanting to know more, the agenda and talks are posted on the SOS17 website: http://www.csm.ornl.gov/workshops/SOS17/
