Nextcloud benchmarks

“Nextcloud, by its nature, scales extremely well across multiple cores and our tests show up to 50% better performance than a similarly priced Intel system.”

Using equipment provided by the Works on Arm program, Nextcloud evaluated their file sharing server software on Cavium ThunderX hardware.

High-performance computing

Sandia “Astra” supercomputer

HPCwire writes: “On track for deployment at Sandia National Labs later this year as part of the NNSA’s Arm-centric Vanguard project, Astra will be the world’s largest Arm system ever built, according to HPE.”

The Astra system will incorporate HPE Apollo 70 nodes – 2,592 two-socket systems using a 28 core variant of the ThunderX2 processor that runs at 2 GHz – for a total of 145,152 cores in the design. Storage will be provided by an all-flash Lustre parallel file system based on HPE’s Apollo 4250 storage server nodes, and networking uses a 100 Gb/sec EDR InfiniBand interconnect from Mellanox Technologies.

Fujitsu Post-K

The Fujitsu Post-K project is design to “create the world’s highest-performing supercomputer, capable of tackling a broad range of applications to solve problems not only in the area of science and technology, but to play a role in a wide variety of issues in society.”

To accomplish this goal, Fujitsu has worked to design an Armv8-A CPU with 512-bit SVE scalable vector extensions. It is targeted to run Linux (RHEL-based) plus the McKernel, a lightweight kernel developed at RIKEN specifically for low-overhead high performance computing.

The Post-K prototype will be exhibited at ISC 2018, a significant international conference and exhibition for high performance computing, which will be held in Germany from June 24-28.

Modular Microserver Data Center

Modular Microserver DataCentre (M2DC) investigates, develops and demonstrates a modular, highly-efficient, cost-optimized server architecture composed of heterogeneous microserver computing resources, being able to be tailored to meet requirements from various application domains such as image processing, cloud computing or even HPC.

The M2DC team will be present at ISC 2018 exhibiting the latest hardware and software.

Single-board computers and arm64 desktops

TERES-I laptop from Olimex booting Armbian

TERES-I is a DIY Free Open Source Hardware and Software laptop with arm64 and x86 processors from Olimex. The arm64 system is based on an Allwinner A64 CPU. The Armbian project reports that they have this system booting into the Armbian Stretch desktop from an SD card.


The NanoPC-T4 is a Rockchip RK3399 based arm64 board from FriendlyArm. It has 4GB LPDDR3 RAM, 16GB eMMC flash, onboard 2.4G & 5G dual-band WiFi module and a full standard M.2 PCIe interface which supports an NVME SSD high-speed hard drive.

64-bit TianoCore UEFI for the Raspberry Pi 3 (with devices, Linux, FreeBSD and Windows on Arm!)

Andrei Warkentin (@andreiw on Github) has a port of 64-bit TianoCore UEFI firmware for the RPi3/RPi3B+ platforms, based on Ard Bisheuvel’s 64-bit and Microsoft’s 32-bit implementations. This is meant as a generally useful 64-bit UEFI implementation for the Pi3, good enough for most kinds of UEFI development and good enough for running real operating systems.

TianoCore is an open source implementation of the Unified Extensible Firmware Interface (UEFI), a critical piece of firmware used during the boot process on modern server systems.

Macchiatobin booting Windows 10

Andrei Warkentin reports success booting Windows 10 using stock UEFI 17.10 on a Macchiatobin ‘Single Shot’ board from Solid Run. He writes “lightning fast boot compared to Pi 3”.

NEMS Linux

NEMS is Nagios Enterprise Monitoring Server for Single Board Computers. It is a modern pre-configured, customized and ready-to-deploy Nagios Core image designed to run on low-cost micro computers. At its core NEMS is a lightweight Debian Stretch deployment optimized for performance, reliability and ease of use.

NEMS targets the Raspberry Pi hardware, and has recently been ported to the Pine A64+.

Cluster computing

Kubernetes dashboard on Arm with RBAC

“In the recent guide about setting up Kubernetes 1.9.0 using kubeadm on Raspberry Pis, RBAC was enabled by default. This blog post will show how to run the Kubernetes dashboard with RBAC enabled.”

Languages, compilers, and libraries

flang work in progress (Fortran compiler for LLVM)

“Flang is to Fortran as Clang is to C/C++.”

Flang is a Fortran compiler that targets the LLVM compiler back end. Work is in progress with code contributed by Cavium to port Flang to arm64, as noted on the “flang-compiler” Github repository.

Operating Systems

Oracle Linux 7 Update 5 GA

Wim Coekaerts from Oracle has announced the general availability of OracleLinux 7 (update 5) 64-bit Arm systems (aarch64). ISOs can be downloaded from MOS (“My Oracle Support”) for existing customers. “Once it’s on edelivery, everyone can just download it and use it.”

The system features MySQL 8 version mysql-community 8.0.11-1. Compiler support includes GCC 7.3 and GoLang 1.10. It ships with Docker 17.12, and Docker arm64 OracleLinux are also available on DockerHub.


ISC High Performance 2018, June 24-28 2018, Frankfurt Germany

ISC High Performance is dedicated to tackling HPC technological development and its application in scientific fields, as well as its adoption in commercial environments. The conference dates are June 24-28, 2018, in Frankfurt Germany.

Two sessions are of particular interest:

ARM for HPC Co-Design Opportunities: “In this BoF we want to discuss/identify the key technologies that the HPC user community can help to co-design to have an impact on future ARM HPC systems.” Monday, June 25th, 4pm – 5pm.

GoingARM for HPC: “GoingArm for HPC all about sharing experiences and knowledge on using, deploying or developing new technologies for Arm HPC systems.” Thursday, June 28th, 9am – 6pm.

Linaro Connect, 17-21 September 2018, Vancouver BC

Since 2010, Linaro Connect has been the event to attend if you are interested in open source software development for Linux, tools and the various vertical segment ecosystems that use Arm processors. While the event continues to evolve, one thing stays the same – it revolves around engineering and will consist of a mix of industry keynotes, engineering presentations and discussions, and collaborative engineering hacking sessions.

LLVM Developers Meeting, October 17-18 2018, San Jose

John Regehr writes: “PSA for students and professors doing LLVM-related research: you really want to be attending these dev meetings”.

The LLVM Developers’ Meeting is a bi-annual 2 day gathering of the entire LLVM Project community. The conference is organized by the LLVM Foundation and many volunteers within the LLVM community. Developers and users of LLVM, Clang, and related subprojects will enjoy attending interesting talks, impromptu discussions, and networking with the many members of our community. Whether you are a new to the LLVM project or a long time member, there is something for each attendee.

October 17-18, 2018, San Jose California.
