Case Study: Texas Advanced Computing Center doubles computing capacity with Cornelis Networks' Omni-Path

Texas Advanced Computing Center Doubles Computing Capacity with Stampede2

The Texas Advanced Computing Center (TACC) needed to significantly expand its computing capacity to support a growing number of researchers in open science, who were submitting proposals at five to six times the capacity its original Stampede system could handle. The challenge was to deploy a new high-performance computing solution that could handle both highly parallel and less scalable workloads, enabling TACC to solve bigger problems for a wider research community.

Cornelis Networks's Omni-Path fabric was implemented as the critical interconnect for TACC's new Stampede2 supercomputer, which also utilized Intel processors. The solution resulted in a powerful heterogeneous system that doubled TACC's capacity. Researchers achieved significant performance speedups, from 1.5x to over 6x faster per node on various applications, allowing Stampede2 to support groundbreaking research in fields from medicine to weather forecasting.
