In this video from the 2019 Stanford HPC Conference, Michael Aguilar from Sandia National Laboratories presents: ASTRA – A Large Scale ARM64 HPC Deployment.

This talk will discuss the Sandia National Laboratories Astra HPC system as mechanism for developing and evaluating large-scale deployments of alternative and advanced computational architectures.

As part of the Vanguard program, the new Arm-based system will be used by the National Nuclear Security Administration (NNSA) to run advanced modeling and simulation workloads for addressing areas such as national security, energy and science.

By introducing Arm processors with the HPE Apollo 70, a purpose-built HPC architecture, we are bringing powerful elements, like optimal memory performance and greater density, to supercomputers that existing technologies in the market cannot match,” said Mike Vildibill, vice president, Advanced Technologies Group, HPE. “Sandia National Laboratories has been an active partner in leveraging our Arm-based platform since its early design, and featuring it in the deployment of the world’s largest Arm-based supercomputer, is a strategic investment for the DOE and the industry as a whole as we race toward achieving exascale computing.”

With Astra, a major stepping stone in HPE’s path to exascale, HPE is delivering over 2.3 theoretical peak petaflops of performance4, 33% better memory performance than traditional market offerings5, and greater system density. The NNSA, an agency within the DOE that is responsible for the management and security of the nation’s nuclear weapons, nuclear nonproliferation, and naval reactor programs, will use Astra to advance modeling and simulation tools to improve analysis on data-intensive science experiments.

Michael Aguilar is a System Administrator for the Astra ARM64 HPC system at Sandia National Laboratories. Michael has been a part of Research and Development of ARM64 HPC systems. In addition, Michael is a member of both the Sandia National Laboratories Production HPC team and the Highly Advanced Architecture team.
