'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.”
