Horizon: New Supercomputer to Replace Frontera in US Academic Research
Horizon, the largest academic supercomputer in the United States, is set to be operational in 2026, featuring 1 million CPU cores and 4,000 GPUs. Funded by the National Science Foundation and developed in partnership with Dell Technologies, Horizon will enhance capabilities in scientific research and artificial intelligence.

Horizon will be built to deliver 300 petaflops, a tenfold increase over the current Frontera supercomputer. It will support complex research projects in fields such as climate science and medicine, utilizing Dell PowerEdge servers with Nvidia technology.
The system is designed for high-density computing, maximizing efficiency for intensive workloads. Planning for Horizon began in 2017, with a strategic pivot towards increased GPU usage reflecting the rising demand for AI capabilities.
It aims to address challenges beyond the reach of existing resources, reinforcing the US's position in scientific innovation. The deployment will also mark a significant upgrade in simulation capabilities, critical for research advancement.
