As a participant in the DoD Programming Environment & Training (PET) Program, TACC provides expertise and support to CWO modelers in DoD using HPC systems.
DOE Portal Development on the SciDAC Grid
Focus Area: DGC
The goal of this multi-site collaborative project is the development and deployment of interoperable portal and web services that can be used on SciDAC Collaboratory grids. Techonologies such as GridPort, GPIR, and NMI Portal Middleware and the SDSC SRB will be utilized.
Engaging People in Cyberinfrastructure [EPIC]
Focus Areas: HPC, SciVis, & DGC
As part of the EPIC proposal, TACC will generalize and distribute content from both its training workshops and academic classes, focusing on the grid computing classes, and refine based on feedback from EPIC participants. This material will then be made available the community at large. This content will help new generations of researchers at other universities learn to deploy and use cyberinfrastructure for research and education.
Enhancing HPC Research Using Clusters
Focus Area: HPC
Clusters have become commonplace as HPC simulation platforms, but there are still many issues to be addressed in terms of configuration, performance, software availability, and porting issues. We are addressing these issues and producing technical documentation to simplify and enhance the use of cluster for HPC.
Evaluation of High-End Visualization Technologies
Focus Area: SciVis
As part of the mission and scope of the Texas Advanced Computing Center, we are investigating and evaluating high-end visualization technologies, from computational engines, GPUs, and high speed storage devices to projection technologies that include scalable tiled displays, high-resolution projection systems and alternatives to traditional flat screen projections.
Feature Detection Techniques and Algorithms
Focus Area: SciVis
We are investigating domain independent, statistically based feature detection schemes that automatically provide generic characteristics of large-scale, time dependent data sets.
GPIR - Grid Portals Information Repository
Focus Area: DGC
GPIR aggregates grid resource data collected by information providers and makes the data available via standard Web service queries.
Gravity Recovery and Climate Experiment (GRACE)
Focus Area: HPC
Applications used by the UT Center for Space Research (CSR) for the GRACE mission are being ported to and optimized for non-vector architectures (Power4/Xeon Cluster).
Grid Portal Toolkit
Focus Area: DGC
The Grid Portal Toolkit (GridPort) GridPort is designed to aid in the development of science portals and application interfaces for computational grids. GridPort facilitates development and utilization of Grid technologies such as the Globus Toolkit, NPACKage and NMI technologies, and OGSI services, from within an integrated, unified API.
Grid-Enabled Portals for Advanced Computing
Focus Area: DGC
The TACC portals program is focussed on enabling the construction of portals that allow scientific researchers to find information about grid resources, operational (status, load, current usage, queued jobs, etc.), technical documentation, notifications, use resources interactively from within the portal to manipulate files and data, and to submit, monitor and delete jobs.
Grid-Enabled Remote & Collaborative Interactive Visualization
Focus Areas: SciVis & DGC
This project is designed to address the growing list of national-scale visualization needs through the research, development, and deployment of grid-enabled visualization tools that provide on-demand, interactive and batch visualization tools. All development is being conducted on the Sun Terascale Visualization machine (maverick.tacc.utexas.edu) that was deployed on the TeraGrid Oct. 1, 2004 to provide remote visualization to the TeraGrid user community.
GridShell: Login shells for the Grid
Focus Areas: HPC & DGC
This project is developing a set of grid enabled shell environments where grid services are mapped into commodity UNIX shells like tcsh and bash. Users may access grid resources transparently within the shell environment aided by software agents. Portable grid workflow is also supported through the scripting capabilities of tcsh and bash.
NMI Middleware for Grid Portals
Focus Area: DGC
TACC is part of the recently funded NSF Middleware Initiative for Grid Portal Development project, a collaborative effort including Argonne National labs, Indiana Univ., University of Michigan, and NCSA. This effort will provide the grid portal community with sharable libraries that utilize Grid technologies, freeing developers to concentrate on the specialized needs of a particular scientific community or collaboratory.
NMI Testbed
Focus Area: DGC
TACC is one of eight universities that participate in the NSF Middleware Initiative INMI) testbed. Managed by Southeastern Universities Research Association (SURA), the testbed is a closely coordinated effort to deploy and evaluate NMI technologies on campus grids.
NPACI Grid Portals
Focus Area: DGC
The TACC NPACI Grid Portals project is focussed on the development of software such as the GridPort Toolkit and the HotPage, and the required infrastructure that integrate common Grid software (such as NPACI NPACKage) into a common single API for application development that will enable advanced distributed computational science to the NSF community.
NSF Extensible Terascale Facility (ETF), or TeraGrid
Focus Areas: HPC, SciVis, DGC, Storage, & Networking
The University of Texas at Austin, led by TACC, received a $3.2M award to in September 2003 to join the TeraGrid on October 1, 2004. UT is contributing leading-edge computational, visualization, and storage infrastructure, plus access to important geosciences data collections.
Parallel HP-adaptive Mesh Refinements
Focus Area: HPC
Development of parallel mesh regeneration & reconciliation for HP-adaptive Finite Element methodology
Perceptually Based Rendering of Complex Time Varying Volumes
Focus Area: SciVis
Volume visualization has been around for some time, but has not yet been embraced as a widely used tool for visualizing volumetric data. This project is conducting research to determine alternative interactive visualization techniques for displaying complex time varying volumes. By incorporating what is known about the human visual system, these methods focus on conveying the underlying information rather than transforming volumetric data to pixel values.
Procedural Visualization of Computational Fluid Dynamics Simulations
Focus Area: SciVis
The purpose of this project is to develop improved visualization tools for CFD researchers through the development of procedural methods to encode and interactively render volumetric data on realistic time accurate CFD simulations. Significant results to date include feature identification and extraction of regions of interest, procedural encoding of volumetric data using Radial Basis Functions, and interactively rendering encoded data on modern GPU hardware.
Scalability & Performance Optimization Team - SPOT
Focus Area: HPC
TACC HPC experts are working with strategic DoD applications to optimize them for maximum performance & scalability and to suggest directions for future development and improvements.
Sparse Direct Factorizations through Unassembled Hypermatrices
Focus Area: HPC
Unassembled hypermatrices are a new matrix storage scheme and factorization strategy that are beneficial for the updated factorizations that feature in hp-adaptive finite element methods.
TIGRE - Texas Internet Grid for Research & Education
Focus Area: DGC
TIGRE is a state-wide advanced computing grid for research and education being developed and deployed by TACC/UT in partnership with Rice University, Texas A&M University, Texas Tech University, and the University of Houston. The project is expected to receive state funding and to commence formally in Spring 2004.
United Devices Campus PC Grid
