The Centre of Excellence will broaden the current scope of interaction and collaboration between BSC and Arm, from HPC to automotive, from scientific computing to real-time systems.

Barcelona Supercomputing Center (BSC) and Arm Research have signed a…

The nature of HPC is on the cusp of a revolution with the rapid adoption of the Python programming language. Python is a rich, object-oriented, interpreted programming language with extensive support for technical computing, data visualization, and most…

GNU compilers and LLVM-based compilers like the Arm Compiler for HPC have three compiler flags in common: -march, -mtune, and -mcpu. These flags control binary code generation, so the correct use of these flags can dramatically improve runtime performance…

Quick Intro

One marketing tag line often heard from Arm is “From Sensors to Supercomputers”, highlighting our company’s ubiquitous nature across so many of today’s technology sectors.  A great example of this is found in the vital…

If you are developing HPC applications, there is a good chance that you have been in contact with Python these days. Whether you use Python to orchestrate large workflows, to quickly put together small prototypes, to visualize data or even to create actual…

Arm’s journey into the HPC market reached several significant milestones this week at SC18.  While Arm has worked diligently on our HPC software stack, it is hugely gratifying to see the quality of those efforts.  A common theme among all the deployment…

In my previous blog on, Running HPC Applications on Arm, I talked about lots of the work that has been going on about getting a wide range of HPC applications running on today’s Arm systems. Today, I want to focus more on some of the key optimizations…

Over the last few months, the Infrastructure team in Arm has been very busy, bolstered by a very warm and enjoyable summer! Some of the key news include the announcement of Arm Neoverse, exciting improvements in the GNU toolchain and the release of Allinea…

Arm Allinea Studio 19.0 is now available, with an updated Arm Performance Libraries (ArmPL) and improved compilers. In this blog, I have captured the highlights of the release. ArmPL has improvements to sparse routine support, support for the FFT Guru and…

At the recent Arm Techcon event, Drew Henry, Arms VP/GM for Infrastructure, unveiled Arm's new brand for infrastructure called "Neoverse". The move by Arm represents a strong commitment to a new line of products aimed at the Infrastructure business…

Hi all!  The story below comes courtesy of Keeran Brabazon.  Enjoy!

Introduction

I’ve been placed in front of an HPC code base for which I have not been the primary developer (in fact I am new to the domain as well as the code). The task at hand is to find…

Arm-based processors have traditionally dominated the mobile world of smartphones, tablets, and embedded IoT devices. However, in recent years, the increasing power demands of data centers, and in particular energy-hungry High Performance Computing (HPC…

Welcome back!

A lot has happened since the last GNU Tool chain performance update. The GCC and glibc communities have been hard at work since, improving the compiler and the library with new usability, language, debugging, security and a myriad of other features…

In Novemeber 2017, a new Top500 ranking was added to highlight the diversity of HPC workloads. The newly added benchmark is called High Performance Conjugate Gradient (HPCG), and results are updated on the same 6-month cadence as the other Top500 rankings…

The Arm Instruction Emulator (ArmIE) is a tool that converts instructions not supported on hardware to native Armv8-A instructions, such as those from the Scalable Vector Extension (SVE) instruction set. ArmIE enables developers to run and test SVE binaries…

Between 17-19 September 2018, over 350 researchers, academics and industry experts gathered at Robinson College in Cambridge, UK to discuss the latest trends, opportunities and challenges in computing research. The three days were packed with presentations…

A few people have asked about my new role at Arm and, more directly, about the attractiveness of Arm to the HPC community. I am quick to answer enthusiastically that I view Arm as disruptive to HPC and am happy to have a role here. Today, Hyperion Re…

What is the GNU toolchain?

In this blog we will focus on two components of the GNU toolchain, the GNU Compiler Collection (GCC) and the GNU C library (glibc). A full toolchain contains several vital components like assemblers, linkers and debuggers, but in…

A new class of low-power TCO-optimised appliances with built-in efficiency and dependability enhancements is being developed at EU level by the M2DC project. It is easy to integrate with a broad ecosystem of management software and fully software-defined…

For the better part of a decade now, Arm has been striving to push into the server platform market and making great strides in terms of ecosystem, infrastructure IP and architecture. Leveraging this great work, more and more SoCs from silicon partners…
