How HPE and Arm software collaboration reflects importance of HPC cross-platform development

With the growing shift to using diverse platforms for tackling HPC application efficiency, HPE’s adoption of popular cross-platform HPC software solutions from Arm could not be more timely.

Arm_blog.jpgArm and HPE are working together to offer a comprehensive software portfolio to help high-performance computing (HPC) users maximize the efficiency of HPC applications on any platform. The cross-platform tools from Arm include Arm Forge, the debugger and profiler suite, and Arm Performance Reports for understanding and improving software performance. The collaboration ensures future-proof development support for HPE customers on diverse HPC platforms today and going forward.

I see two key trends currently at work in HPC are leading organizations to consider a wide range of investment into time and resources in choosing the right platform for the right type of HPC application.

First, the continuous push for more accurate and intricate simulations and, secondly, the growth of machine learning. These developments demand more powerful systems than ever before, sometimes using the equivalent energy as what is required to run a high-speed train. While we’re already seeing GPU being used successfully for machine learning, the future of HPC beyond that requires systems to be hundreds of times faster and more efficient than today’s fastest supercomputers.

When application performance across platforms is increasingly important

With the addition of the HPE Apollo 70 Arm®-based system to the portfolio of Intel x86 and GPU accelerators, HPE is the perfect example of how the market is ensuring that consistency and familiarity in diverse systems can be used to great effect.

The Astra HPE Apollo 70 system, deployed by Sandia National Laboratories, is one of the first validated systems for running large-scale high-performance applications on Arm-based systems. Astra will consist of 2,592 compute nodes, of which each is 28-core, dual-socket, and will be at a theoretical peak of more than 2.3 petaflops, equivalent to 2.3 quadrillion floating-point operations, or calculations, per second (FLOPS) making it the world’s largest Arm-based supercomputer.

HPE is also the solutions provider spearheading the Catalyst UK Project, running across the Universities of Edinburgh, Bristol and Leicester. The goal is to explore the potential of Arm-based systems, complementing its use of other platforms across a broad spectrum of HPC workflows, including simulations of gravitational waves, fundamental particle physics calculations and AI research, which involves processing enormous amounts of data and requires extremely high memory bandwidth.

Why HPE and Arm collaboration is good news for HPC platform developers

Against this backdrop, it’s never been more important that no matter which HPC platform is used, developers need to be able to build and run applications to maximum effect.

The collaboration between HPE and Arm ensures users can still turn to just one familiar suite of tools to understand more about application performance, determine the right choice of architecture and manage ongoing optimization and development needs. Arm Forge is still the market’s only cross-platform debugger and profiler suite available for HPC. It’s proven itself as hugely effective in profiling high performance applications through a sampling method which keeps the profiler lightweight enough to prevent any disruption to the overall performance of the world’s largest applications. The collaboration also underlines the growing opportunity for developers to port to new, innovative hardware and platforms and for targeting the software inefficiencies that hinder performance on existing systems. 

With developers seeking increasing levels of efficiency and performance from HPE systems when running applications on any platform, it’s clear that software efficiency has a big part to play. With 80% of the world’s top 25 supercomputers continuing to use and trust Arm’s cross-platform tools for porting, debugging and profiling applications, such software enhancing tools will play an important role in aiding platform selection and software optimization for HPC in the future.
