TACC promotes discoveries and advances enabled by supercomputing, and provides information to create a general public awareness of the role of computing and technology in science and society.

Cosmic Slurp

Somewhere in the cosmos an ordinary galaxy spins, seemingly at slumber. Then all of a sudden, WHAM! A flash of light explodes from the galaxy's center. A star orbiting too close to the event horizon of the galaxy's central supermassive black hole is torn apart by the force of gravity, heating up its gas and sending out a beacon to the far reaches of the universe.

In a universe with tens of billions of galaxies, how would we see it? What would such a beacon look like? How would we distinguish it from other bright, monumental intergalactic events, like supernovas? Read more >>

Maverick at TACC tackles big-scale data visualization (Interview – Part 1)

The Texas Advanced Computer Center at The University of Texas at Austin just deployed Maverick, a unique, powerful, high performance visualization and data analytics resource for the open science and engineering community.

I spoke with Kelly Gaither, Ph.D., the principal investigator on the project and TACC's director of Visualization, at the TACC Visualization Laboratory (Vislab) on campus, just a few weeks after the deployment, for an overview on Maverick and other features of TACC and the Vislab. Read more >>

Blast Off! Journey through TACC's Vislab at Explore UT

Earlier this month, several hundred students and their families explored outer space in the Texas Advanced Computing Center's (TACC) Visualization Laboratory (Vislab) through the biggest open house in Texas — Explore UT.

With more than 400 performances, exhibits, activities and lectures across campus, Explore UT gives students an inside look at what the university has to offer future Longhorns. Read more >>

Technip, TACC Design Safer Offshore Oil Platforms

Technip is an oil services company that specializes in offshore platform design, construction, and installation.

Technip recently redesigned one of its floating platforms based on simulations run on Stampede. The redesign led to crucial improvements including reduced vortex- induced motion and improved stability, which will increase safety for workers and decrease the likelihood of oil spills in the future.

TACC Brings City and Regional Planning into 3D

Visualization, HPC and storage experts and technologies contribute to growth scenarios for Central Texas region.

How will the Central Texas region evolve over the next 20 years? A newly developed suite of analytics tools developed in part by the Texas Advanced Computing Center (TACC) is being used to provide a better understanding of the impacts of various development patterns, such as:

  • What types of housing and business development should be planned?
  • How concentrating growth can maximize a community's infrastructure?
  • Where natural resources should be preserved?
  • How can communities promote better health?
  • How the region can ensure all segments of the community have access to education and jobs?

Protecting Vulnerable Freshwater Aquifers Critical Task

LiveScience -- Water is a critical resource in Florida, where freshwater for communities and farms often is scarce or — during tropical storms — overabundant. In times of high water demand or during storm surges, seawater can intrude into the Florida's aquifers, potentially contaminating the state's water supply.

Researchers worked with experts at the Texas Advanced Computing Center (TACC) to visualize groundwater flowing through these holes. Combining fluid dynamics calculations with computed tomography (CT) data and other imaging techniques, they created 3D animations of groundwater flowing through core samples of karst limestone collected in the region, specifically investigating the rock's permeability.

Let There Be Light

TACC's Ranger supercomputer helps researchers generate realistic light signals from a black hole simulation.

Astrophysicists became deeply interested in black holes in the 1960s, but the idea of an event horizon was first intimated in a paper by Karl Schwarzschild published after Einstein introduced general relativity in 1915.

ISC'14 S. African Student Cluster Team Visits Austin

Building the next generation of high performance computing professionals is an important part of the mission at TACC. For the second time in as many years, TACC welcomed a new ‘cluster' of students from South Africa to Austin as they prepare for the International Supercomputing Conference (ISC) Student Cluster Competition this June.

Data: The Next Frontier

Texas Enterprise -- "More data don't guarantee better decisions. … The right data, however, do," said Dr. Michael Hasler, program director for the business analytics Master's program at the McCombs School of Business. The idea of "Big Data" is ubiquitous, and companies often believe they need to become part of the big data push without necessarily understanding why or how. But on Jan. 22 at the Texas Enterprise Speaker Series, Hasler reminded the audience gathered at the J.J. Pickle Research Campus that data's real value isn't in merely being collected, but in how it helps us make better decisions.

Heavy Metal in the Early Cosmos

Simulations on XSEDE/TACC supercomputers shed light on the formation, explosion of stars in the earliest galaxies.

Ab initio: "From the beginning." It's a term used in science to describe calculations that rely on established mathematical laws of nature, or "first principles," without additional assumptions or special models.

Podcast: TACC's Stampede Supercomputer: First Year in Review

HPCwire -- Today we talk to Dan Stanzione, acting director at the Texas Advanced Computing Center. We'll be checking in with the first year of progress on the Stampede supercomputer and talking about some of the lessons learned working the novel architecture and high user demand. Specifically, we discuss their use of Xeon Phi and the challenges and opportunities it's presented, as well as hone in on specific applications that have kept the machine full since its kickoff.

Dan C. Stanzione Jr. Named Acting Director of Texas Advanced Computing Center

TACC Deputy Director Dan C. Stanzione Jr. has been named as acting director of the Texas Advanced Computing Center (TACC) at The University of Texas at Austin. After more than 12 years of leading the center, Jay Boisseau resigned as director on Jan. 15, 2014.

TACC has a national reputation as one of the leading academic supercomputing centers in the United States providing high-end advanced computing resources and services to researchers nationwide; conducting leading research and development projects; and providing training and education for the local and national scientific community.

Putting Quarks on a Virtual Scale

Supercomputing simulations help to predict research on the fundamental nature of the universe, characteristics of subatomic particles.

For the past several years, much of the attention in particle physics has focused on the Higgs Boson, so one could be forgiven for thinking that the rest of the subatomic particle world has been figured out. In fact, many open questions remain about the precise masses and decay rates and characteristics of other particles, including mesons, quarks and gluons, which make up the protons, neutrons and electrons we're familiar with.

TACC Addresses Need for User-Friendly, Inexpensive Science Gateways

The Texas Advanced Computing Center (TACC) at The University of Texas at Austin has released the Agave API, a cloud-based science-as-a-service platform for gateway development, and Gateway DNA, a collection of open source components enabling the rapid development of science gateways.

"Historically, science gateways have been built by small teams of extremely passionate and talented individuals," said Rion Dooley, lead architect of the Agave API and manager of TACC's Web and Cloud Services group. "Each gateway would recreate infrastructure from the ground up with very little code sharing between them. While the results were impressive, the cost was enormous. As a result, innovation slowed to a crawl year over year as the majority of time on new projects was spent reinventing the wheel."


Stampede, one of the most powerful supercomputers in the world for open science research, celebrated its first birthday on January 7, 2014, by completing more than 75,000 years of scientific computations – not bad for a one-year-old. Here are some facts, figures & science highlights that capture the comprehensive impact of the system. Stampede and its academic partners will continue to enable promising computational research in 2014 and beyond.
