Summary
More than 600 compute nodes in TACC’s Stampede3 supercomputer have been formally accepted after a Cornelis CN5000 networking upgrade, strengthening a key production partition used by the U.S. open science community.
WRF weather-model testing showed application performance gains of 53% to 71% across multiple scaling points, indicating faster simulations and better use of shared computing capacity.
Stampede3 serves more than 5,000 active researchers each year across weather forecasting, engineering simulation, computational science and data analytics, where growing workload complexity has made data movement a bigger bottleneck.
The acceptance extends Cornelis’ role at one of the world’s leading academic supercomputing centers and underscores how network upgrades, not just new processors, can materially raise scientific throughput.
