HPE is building the world's first petascale supercomputer powered by ARM processors. It will reach 2.3 petaflops of peak performance:

PALO ALTO, Calif., June 18, 2018 – Hewlett Packard Enterprise (HPE) today announced its collaboration with Sandia National Laboratories and the U.S. Department of Energy (DOE) to deliver the world's largest Arm supercomputer. As part of the Vanguard program, Astra, 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.

[...] Astra will be deployed at Sandia National Laboratories and will run on the HPE Apollo 70. This purpose-built HPC platform is based on the Cavium ThunderX2 Arm processor. Astra is comprised of over 145,000 cores in 2,592 dual-processor servers and offers greater density with four compute nodes in a 2U form factor.

The supercomputer will draw 1.2 MW, giving a possible efficiency of 1.92 gigaflops per Watt. That's only good enough to put it around #131 on the November 2017 Green500 list (the top 5 systems exceed 14 gigaflops per Watt).

    Thanks to the local flash storage and the eight memory channels on each ThunderX2 socket, Astra is likely to be especially adept at analytics and other data-demanding codes. In particular, the eight-memory-design represents a 33 percent improvement on Intel’s six-channel implementation of its Xeon Scalable processor. The better bandwidth is one of ThunderX2’s most important differentiating features and represents an attempt to provide a more balanced relationship between compute capacity and memory speed. (Note that you don’t need an ARM processor to this; AMD has the same eight-memory-channel design with its x86 EPYC processor.)

    I wonder what the sustained performance in memory intensive application will be ?
