WHITE PAPER: THE CRAY® XC™ SERIES SCALABILITY ADVANTAGE

The sheer scale and high global bandwidth of Cray XC systems enable the study of new problems that would not run on other systems, opening the door to discovery.

Cray XC series supercomputers integrate an HPC-optimized Aries™ interconnect with a high-bandwidth, low-diameter network topology called Dragonfly, providing state-of-the-art performance on the most demanding applications. This white paper describes aspects of the Cray XC system that were designed for scalability, enabling Cray to deliver systems like “Trinity.”

Learn how Trinity performs well in scalability metrics, including:

Accelerating key operations, both between and within nodes, allowing more CPUs to be used on a given problem.

Reducing memory use per process to 30 times less than that of EDR Infiniband.


Providing substantial energy savings using highly integrated network components and a low-diameter Dragonfly network.

The Trinity supercomputer provides computational capability for the demanding workloads of the National Nuclear Security Administration (NNSA).
