‘Horizon’ Supercomputer Will Make Austin the Center of U.S. Research Power
AUSTIN, Texas — The next wave of scientific discovery is being built right here in Central Texas.
The Texas Advanced Computing Center (TACC) at The University of Texas at Austin is teaming up with Dell Technologies and NVIDIA to launch Horizon, which will become the largest academic supercomputer in the United States when it goes online in 2026.
Designed to be a major engine for open science, Horizon will help researchers tackle some of the toughest problems of our time—from extreme weather forecasting to medical breakthroughs to national security.
A Texas-sized leap in computing power
Horizon will deliver 300 petaflops of performance—making it ten times faster than TACC’s current supercomputer, Frontera. For researchers, that means bigger projects, faster insights, and entirely new possibilities.
“It’s really exciting for Austin and for the University of Texas,” said Dan Stanzione, Associate Vice President for Research at UT and Executive Director of TACC. “We’ll have the largest academic computing resource in the country. Researchers will have unparalleled access to computing anywhere in the world.”
A supercomputer built in Central Texas
Horizon isn’t just located in Austin—it’s being built here, too.
Dell is designing the integrated racks.
Final assembly is happening in Georgetown.
The system will be housed in a Round Rock data center.
NVIDIA chips and VAST storage—both companies with Austin teams—power the hardware.
“Everyone involved has an Austin tie,” Stanzione said. “Finally deploying one of these major systems in the Austin area is pretty exciting.”

What Horizon will do
In its first year, TACC expects hundreds of research projects to run on Horizon. Some of the earliest will focus on Texas-specific challenges, such as:
More accurate hurricane and storm surge forecasts
Disaster resilience modeling for the Gulf Coast
Healthcare and drug discovery
New materials and battery development
Horizon will also become the AI hub for UT Austin, enabling breakthroughs in machine learning and large-scale data analysis.
Keeping a giant cool
Running a supercomputer this large takes serious engineering. Each cabinet draws around 225,000 watts, requiring advanced cooling solutions.
Propylene glycol will flow directly across the chips, while chilled water circulates through rear-door radiators. In total, the system will move about 400,000 gallons of water per hour to keep everything stable.
What Dell says
For Dell Technologies, Horizon is a major step forward for the region and the research community.
“Horizon delivers over 300 petaflops of performance—ten to twelve times faster than Frontera,” said Seamus Jones, Director of Server Engineering. “It will help researchers break boundaries and drive advancements in technologies we haven’t even imagined yet.”
A new era for Texas innovation
With Horizon, Austin is poised to become the nation’s center for high-performance academic computing. The supercomputer will serve thousands of researchers across disciplines—and could reshape how science is done for years to come.

New Texas law tightens rules for autonomous vehicle companies, including Waymo
AUSTIN, Texas — Self-driving cars have become a common sight on Austin streets, but a new Texas law is adding tougher requirements for the companies behind the wheelless vehicles.
Senate Bill 2807 imposes stricter rules on autonomous vehicle companies operating in the state, including state authorization, emergency response plans for law enforcement, and a public portal where residents can verify operators and file safety complaints.
The changes come as Austin continues to track incidents involving autonomous vehicles. The city’s autonomous vehicle dashboard shows 75 incidents in 2026, including a collision, eight near misses, and seven incidents of ignoring police direction.
Attorney Drew Gibbs, a partner at Slingshot Law, said one crash involved a Waymo vehicle.
“There was a T-bone collision. A pretty serious T-bone collision where a Waymo just crashed into the side of my client’s vehicle,” Gibbs said.

One of the incidents of ignoring police direction happened during the mass shooting on West Sixth Street back in March, when three people died, and 15 others were injured.
Austin Police Association President Michael Bullock said autonomous vehicles can struggle in unusual situations.
“It didn’t impede on anything in the moment, but it’s not necessarily uncommon where these vehicles don’t quite know how to deal with these one-off scenarios,” Bullock said.
The new law requires autonomous vehicle companies to be authorized by the state, to provide an emergency response plan for law enforcement, and to participate in a public-facing portal that allows the public to verify operators and submit safety complaints.
Kara Kockelman, a professor of transportation and engineering at the University of Texas at Austin, welcomed the added oversight.
“I’m glad that the state is taking this a bit more seriously now,” she said. “It’s important not to just let others slip in without kind of meeting those basic minimums.”
Bullock said the emergency planning requirement may not make a major difference in fast-moving situations. Asked how impactful it is to have a fully laid out emergency response plan, Bullock said, “These plans are great, but it takes time to work through all of those versus the immediacy of having someone behind the wheel.”
The four autonomous vehicle companies operating in Austin — Waymo, Zoox, AV-Ride, and Tesla — are all state-authorized.
The Texas DMV said an autonomous vehicle company can lose its authorization to operate in Texas if the agency deems the vehicles are operating in a way that endangers public safety.
Waymo was contacted for comment, but had not responded.

Austin OKs $2.35 billion of revenue bonds, eyes GO bond election
Michael Dorman
Austin, Texas, is revving up to sell $2.35 billion of debt for a convention center and a wastewater treatment plant, while a legal battle continues over bonds to help finance a light rail system.
Processing Content
The bond boom comes as the city council voted on Thursday to pursue the development of a $390 million baseline general obligation bond package for the November ballot despite a call by Mayor Kirk Watson to wait until 2028.
“I believe we can and we should bring forward significant investments in the future,” he said. “In fact, if we restore compliance with our financial policies and we maintain the discipline we actually will have greater future capacity to do more for this community in 2028.”
A bond election would
The city, which last held a successful GO bond election in 2022 for $350 million of debt for affordable housing, had $1.03 billion of unissued voter-approved GO bond authorization as of the Sept. 30 end of fiscal 2025. Last year,
On Thursday, the city council signed off on a $34.5 million wrongful prosecution and conviction settlement with four individuals to be financed through the sale of non-voter-approved GO bonds.
The council approved up to $1.35 billion of special tax revenue bonds on May 21 for a $1.6 billion project to replace the city’s now-demolished convention center with a facility that will increase rentable event space to 620,000 square feet from 365,000 square feet.

The bonds are backed with revenue from certain city hotel occupancy taxes and incremental state tax revenue generated within a project finance zone the city established in 2024. Amounts and timings for issuing the debt are being determined, according to the city, which filed a petition with a Travis County District Court for an expedited validation of the bonds.
An ordinance approved in October
The city also plans to refund hotel occupancy tax-backed debt issued for the prior convention center in order to pledge a 4.5% hotel tax for the upcoming bonds.
“The refunding bonds are a separate, but related item to the expansion bonds and will only be secured by 2% venue HOT,” city documents said. “The 2% venue HOT will not be pledged to the expansion bonds and will cease to be collected upon final maturity or early payoff of (the refunding bonds).”
A petition drive that would have delayed the project fell 494 signatures short of a requirement for 20,000 valid signatures of registered voters, Austin City Clerk Erika Brady determined in November.
Petition backers are appealing a district court’s refusal to force validation in state appellate court after the Texas Supreme Court dismissed
The petition drive by Austin United PAC and others sought a ballot measure to stop the demolition and reconstruction of the convention center for seven years — or until the project was approved by voters — and prioritize city funding for local live music, arts, cultural, and outdoor tourism.
The Austin City Council also approved as much as $1 billion of water and wastewater system revenue bonds last month for the Walnut Creek Wastewater Treatment Plant expansion and enhancement project. The bonds will be used to obtain a direct low-interest loan from the U.S. Environmental Protection Agency’s Water Infrastructure Finance and Innovation Act program.
Other financing sources for the $1.5 billion project are $59 million from the Texas Water Development Board Clean Water State Revolving Fund program and funding from Austin Water.

The plant, which serves more than 50% of Austin and operates at a treatment capacity of 75 million gallons per day, will have its capacity increased to 100 MGD, helping meet future demand and requirements set by the Texas Commission on Environmental Quality for Austin’s projected growth of 1.5 million by 2040, according to a city statement.
A legal logjam over a light rail system eased May 22 when the Texas Supreme Court finally ruled on a procedural issue related to an initial $150 million of bonds for the project. The high court ordered a Travis County Court judge to decide whether the bonds’ issuer, the Austin Transit Partnership, a nonprofit corporation created by the city and Capital Metro Transportation Authority, has standing to seek court validation for the debt.
City taxpayers who filed a lawsuit in 2023, along with the Texas Attorney General’s Office have been challenging the legality of the bonds, which would be paid off with a portion of Austin’s operation and maintenance property taxes
Escalating costs led ATP to downsize Project Connect to an initial less than 10-mile, 15-station system with a similar price tag. The completion of a federal environmental review in January allowed the project to continue a process
ATP said Project Connect is moving forward with construction scheduled to begin next year.
“We are confident in our case and look forward to our day in court,” ATP said in a statement. “The pending litigation has not slowed our progress advancing Austin light rail, which has hit major milestones in the federal funding process, design, and pre-construction work this year.”
Bill Aleshire, an attorney who filed the taxpayers’ lawsuit, cautioned that several issues remain before the court, including the legality of the downsized project and the ability to pay off bonds with property tax revenue that is supposed to be used for operations.
“Their federal funding is uncertain, their ability to issue bonds is uncertain, and they just stubbornly will not listen to us and say it’s time to pause Project Connect and rethink it, that maybe rail isn’t the best way to go at this time and maybe we can’t afford it at this time,” he said.
