Projects

This page describes some of the projects that I am involved in, or have been involved in. This page is still being developed.



Cactus Code

The Cactus Framework is an open source, modular, portable, programming environment for collaborative HPC computing. The Cactus Framework allows large-scale cooperation across the globe, where individual groups design and maintain individual code modules, relying on Cactus to make these modules interoperate. Cactus is involved in many of my projects, including XiRel, ALPACA, Blue Waters, UCoMS, CFD Toolkit, CoMI, and CyberTools.





UCoMS

The UCoMS project, sponsored by the Department of Energy and the Louisiana Board of Regents, is researching and developing new Grid computing and sensor network technologies for the management of energy resources.





CyberTools

The CyberTools project brings together leading researchers in computational science from across Louisiana to develop an advanced cyberinfrastructure which provides the software tools to leverage the LONI resources for scientific research. Now funded by the NSF through the EPSCOR Research Infrastructure program, CyberTools will work with targeted application groups to integrate, extend, and deploy a range of coordinated services necessarily for next generation applications. Organized into four workpackages, CyberTools is a collaboration of nine Louisiana research institutions.





CFD Toolkit

The CFD Toolkit is an on-going research initiative at the Center for Computation & Technology (CCT), which is building a collaborative problem-solving environment for grand challenge fluid flow and transport problems. The CFD Toolkit is built using the Cactus framework and will support applications in coastal modelling, and astrophysics.





LONI Institute

The LONI Institute was created as a growing, economic development-oriented, academic collaborative, where scientists focus on the computational and scientific research essential to solving challenging problems in materials science and biology. The LONI Institute is based on the resources of the Louisiana Optical Network Initiative, or LONI, a high-speed, fiber optic network that connects supercomputers at Louisiana's major research institutions.





COMI: Coastal Modeling Infrastructure

This DOD funded project is using Cactus as the basis of a new integrated framework for coastal mod- eling, applied to the Louisiana delta region.



SCOOP Project

The SURA Coastal Ocean Observing and Prediction (SCOOP) program is integrating diverse efforts and empowering a virtual community of scientists with the tools, resources, and ideas that lead to discovery. The purpose of SCOOP is to promote the effective and rapid fusion of observed oceanographic data with numerical models and to facilitate the rapid dissemination of information to operational, scientific, and public or private users.





Virtual Collaborative Environments

Second Life





GridSphere

The GridSphere portal framework provides an open-source portlet based Web portal. GridSphere enables developers to quickly develop and package third-party portlet web applications that can be run and administered within the GridSphere portlet container.





Computational Chemistry Grid

The "Computational Chemistry Grid" (CCG) is a virtual organization that provides access to high performance computing resources for computational chemistry with distributed support and services, intuitive interfaces and measurable quality of service. The CCG client, GridChem, is a Java desktop application that provides an interface to integrate the hardware, software and middleware resources necessary to solve quantum chemistry problems using grid technologies.

SAGA

SAGA provides the missing link between the application level and various grid middleware packages. The core idea of SAGA is similar to that of the well established MPI message passing standard, but at a much higher (grid) level.





GRIKSL

The GriKSL project, funded by DFN-Verein and involving the Albert Einstein Insti- tute and the Konrad Zuse Zentrum aimed to develop new tools and techniques to move compute-intensive applications to the Grid. It built on the results of the predecessor project TIKSL, and concentrated on three main areas which were important for the fu- ture development of Grid technologies: Grid-awareness of applications; Description and hand ling of large scale distributed data sets; Tools for remote and distributed data visu- alization. The Cactus Framework was used to build prototypes and provide application drivers for much of the work of GriKSL.





EU Astrophysics Network

The EU network for Theoretical Foundations of Sources for Gravi- tational Wave Astronomy of the Next Century: Synergy between Supercomputer Simulations and Approximation Techniques involved many partners in Europe, including Max-Planck Institut fuer Gravitationsphysik, University of Jena, Observatoire de Paris, University of Valencia, University of Palma, University of Thessaloniki, Uni- versity of Rome, SISSA, Southampton University, University of Portsmouth. The project focussed on training graduate students and postdocs for research in gravitational wave astronomy, and Cactus formed the core computational framework. One outcome of this project was the Whisky Code.
