Astra is a petascale ARM supercomputer designed for Sandia National Laboratories expeced to be deployed in mid-2018. This is the first ARM-based supercomputer to exceed 1 petaFLOPS.
Contents
History
Astra is an ARM-based supercomputer expected to be deployed at Sandia National Laboratories. The computer is one of a series of prototypes commissioned by the U.S. Department of Energy as part of a program that evaluates the feasibility of emerging high-performance computing architectures as production platforms to support NNSA's mission.
Overview
Astra is the first ARM-based petascale supercomputer. The system consists of 5,184 Cavium ThunderX2 CN9975 processors with a 1.2 MW power consumption for a peak performance of 2.322 petaFLOPS. Each ThunderX2 CN9975 has 28 cores operating at 2 GHz. There are also 108 36-port switches and 3 540-port spine switches.
