The accuracy of weather and climate predictions is becoming increasingly important. Having the ability to predict extreme events in advance helps us prepare and thus minimize impact. Increasing capability of HPC and weather and climate modeling is key…

Moving High Performance Computing (HPC) workloads to the cloud has been a trend for some time, but progress has advanced slowly facing resistance due to high costs and performance concerns based on lack of parallel file systems and low-latency networking…

At the start of the month, Amazon Web Services (AWS) announced the launch of their new Arm-based AWS Graviton2 processor, and associated 6^th generation Amazon EC2 M6g, C6g & R6g instances. These chips have four times the number of compute cores with…

A great deal of news that is arrived during the Supercomputing Conference 2019 (SC19) in Denver, Colorado last month. Every year at the SC, we highlight the work and growth of the Arm HPC ecosystem. The focus is on our various partners in this space. At…

The strong growth in HPC, ML/AI, and Big data analytics sectors has mainly been driven by the explosion of new use cases across numerous businesses and areas of research.  In order to stay competitive and sustain progress, IT departments must look at new…

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…

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…

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…

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…

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…

Arm Allinea Studio 18.4 is now available, with an updated Arm Performance Libraries and improved compilers. In this blog, I have captured the highlights of the release, including new Fortran Directives (IVDEP, OMP SIMD), compiler option updates, new math…

本文翻译自Continuous Integration with Arm Forge

为了提高软件，特别是有多人参与的大型软件，的整合性和质量，持续集成(CI)在软件工程中广泛使用。随着代码的增多，优化的深入，高性能计算(HPC)应用也可以通过Jenkins之类的的CI框架来确保软件符合精度和性能的需求。

CI工具其实就是管理项目的在一堆代码和依赖资源上进行并行构建，测试的机器人。他们可以和版本控制 软件，构建系统或者单元测试框架进行对接，以在开发流程中实现更好的集成系统。最后它还可以收集并聚合测试数据来显示应用的健康程度…

Continuous integration or CI is widely used in software engineering to improve software integration and quality, especially for large projects that involve a lot of developers. Naturally, high performance computing (HPC) applications can benefit from…

Arm Allinea Studio 18.3 is now available with updated Arm Performance Libraries and improved compilers.

Math routines - pow, exp, and log - now part of Arm Performance Libraries

Arm Performance Libraries 18.3 includes a new library libamath, with optimized…

I like sleep. Sleep is good. With plenty of sleep I address the day with vigor, and approach the duties of the day with zeal. So, when I discovered how to debug while I slept I was excited and I think that you will be excited too.

How to debug offline…

On Monday April 16, 2018, HPE, in conjunction with Arm and SUSE, announced the “Catalyst UK” program. The program calls for establishing supercomputer deployments at three leading UK universities (Bristol, Leicester, and Edinburgh) to accelerate the growth…

We are happy to announce the availability of Arm Allinea Studio 18.2 version with key new enhancements in Compiler and Libraries.

Arm Compiler now needs a valid license to run

In 18.2, license management is enabled by default for Arm Compiler. You will…

If you are following the server or HPC space closely, then you probably have seen the volume of Arm server news go well beyond 11 in the past week. Most of the news is coming straight out of our server ecosystem which has never been more active and robust…

Memory leaks are a killer of long running applications - memory usage keeps growing until finally the memory supply is exhausted and it's "game over". If you’re lucky the system recognizes your application is at fault and terminates it. If you’re unlucky…

Today, using one of the early examples from the CUDA toolkit, I’m going to introduce a neat feature of CUDA 5 and CUDA 5.5 - dynamic parallelism - and how to use Arm DDT to debug it.

What is CUDA?

CUDA brings highly parallel computing into the graphics…

The Story So Far

In Part 1 I ran Discovar, a life sciences genome assembly code, on one of our internal systems and optimized it to run the benchmark code 7% faster. Of course, physical hardware often performs very differently to cloud-hosted machines…

We humans can survive in almost every environment on our planet and are beginning to step off it. We command fire hotter than the core of a star and freeze atoms at temperatures cooler than the depths of interstellar space. Not bad for squishy sacks of…

It's January 2012 and I'm sitting on a cross-Atlantic flight. Sweat is beading on my brow and it's nothing to do with the cabin temperature. I am not a happy bunny. I'm a very unhappy bunny and somebody is going to pay.

On this fateful…
