Presenters and Software


Sophie Blondel
(CSMD, Computer Science Research)
Xolotl is an open-source, high performance plasma-surface interactions simulator that is currently under development within the DOE's SciDAC program.

Daniel Ciarlette
(ITSD, Client Computing Operations)
SPUDS - the next generation
I will be presenting the current offerings on the Software Product and Update Distribution Service (SPUDS), what we are looking to do with it in the future, and gather comments from researchers.

The Land Ice Verification and Validation toolkit (LIVV) is a python-based extensible software package that provides robust, automated verification and a performance evaluation of continental-scale, dynamical ice-sheet models on LCF platforms. This involves a comprehensive comparison of model performance relative to expected behavior on a given computing platform. LIVV operates on a set of benchmark and test data, and provides comparisons for a suite of community prioritized tests, including configuration and parameter variations, bit-4-bit evaluation, and plots of tests where differences occur.

Benjamin Mayer

Pegasus is a Workflow Management System running on Oak Ridge and other DOE resources that can work with whole terabytes of data, successfully executing on a laptop, campus clusters, grids, and clouds.

Joshua New
(ETSD, Whole Building & Community Integration)
Autotune is an advanced, multi-objective optimization algorithm that has leveraged High Performance Computing (HPC) resources and data-mining of 200+ TB simulation data in order to quickly calibrate inputs describing an object so that simulation output matches measured, experimental data.

Rangan Sukumar
(CSED, Computational Data Analytics)
EAGLE is an algorithmic Graph library for exploratory analysis. Although primarily developed for Cray's Urika, this open source version works on Apache Jena triplestore. We have tested EAGLE to work on desktops, laptops, and cloud services such as Amazon C2. EAGLE can play a critical role in the exploratory analysis of massive heterogeneous graph data (e.g. semantic knowledge graphs). We believe with more support and user feedback, we can create a "MATLAB" for LinkedData.

(CSMD, Computational and Applied Math)
The Toolkit for Adaptive Stochastic Modeling And Non-Intrusive ApproximatioN (TASMANIAN) is a collection of algorithms for approximation of multidimensional functions. The methods are based on Stochastic Collocation/Sparse Grids, where the approximation is constructed from an ensemble of independent realizations of the target functions (i.e., samples). See for more details.

Daniel Wilson
(ETSD, Center for Transportation Analysis)
ORNLReady is an emergency management application that is designed to enable users to maintain situational awareness and coordinate responses in the event of a laboratory emergency. This is accomplished through the use of a GIS platform and using geospatial analysis and tools.
