If you read our previous blog, then you know the community of Arm HPC users has come a long way in a short time. With ISC’22 quickly approaching, we wanted to give a teaser for what you could see by visiting us at the Arm booth (A104). Or by attending some of our Arm and AHUG (Arm HPC User Group) sessions. A lot has changed since the last on-site ISC conference in 2019.
TLDR: Arm servers are now firmly in an era of diversity.
Systems such as RIKEN Fugaku demonstrated a leadership capability that can be achieved with Arm architecture. The reach of the growing number of Cloud providers with competitive platforms for HPC on Arm servers is now making the architecture prevalent in many application domains.
AWS, Oracle Cloud Infrastructure (OCI), and Alibaba Cloud have Arm-based offerings. So does Rescale. Microsoft Azure is in preview with Arm-based instances. And the third generation of Arm servers in AWS – the AWS Graviton3-based C7g instances are now generally available. You need on-prem? Ampere Altra and Altra Max CPUs – with an industry leading 128 cores in a single socket - are available through Foxconn, Gigabyte, Inspur, Supermicro, and Wiwynn. NVIDIA offers the Ampere Altra-based NVIDIA Arm HPC Development Kit and the NVIDIA Grace Superchip is coming soon.
With all that available hardware, HPC users who have trail blazed application development and system deployment for our architecture are being rewarded with choice. That choice is providing competitiveness on execution time, cost and power, and often compellingly so.
Choice and growth have fired the interest and action from commercial software vendors too – EDA software has been already announced. Now, the leading engineering codes from Altair and ANSYS, for example, are available on Arm.
Arm partner platforms executing your software workloads is what drives us. HPC applications are a spectrum of diversity too. At ISC'22, with access to many different Arm HPC platforms now available, we are demonstrating the performance and cost advantages of Arm partner silicon - from molecular dynamics to aerodynamics, and numerical weather prediction to seismic imaging.
Interested in more of the Arm CPU and platform capabilities powering all of this Arm HPC partner silicon? We have you covered there as well. Did you know the Arm Neoverse V1 core – the main compute engine in SiPearl’s upcoming Rhea CPU and in the AWS Graviton3 – can issue up to 15 instructions per clock cycle (that’s a lot, trust us). And the 256-bit wide Scalable Vector Extension (SVE) engines support twice the floating-point throughput and four times the Machine Learning capability of our Neoverse N1 cores. And those V1 cores sit within Arm’s CMN-700 mesh, which can support up to 3TB/s of bi-sectional bandwidth (that’s also a lot). CMN-700 also supports up to 512MB of system level cache (SLC) per system, and can support both DDR5 and HBM2/3 memory devices. On the I/O front, CMN-700 supports PCI Express Gen5 and CXL. In short, there is a lot for an HPC user to like about Arm technology.
Now if you are like us, you are attending ISC’22 to meet your peers and to learn from workshops and sessions. The Arm HPC Users Group (AHUG) workshop this year is not to be missed. There are speakers from the Barcelona Supercomputing Center, Chalmers University of Technology, Edinburgh Parallel Computing Center (EPCC), Freidrich Schiller University Jena, Juelich Supercomputing Centre, Los Alamos, and RIKEN – and speakers from HPC solution providers Atos, AWS, HPE, Huawei, SiPearl, and NVIDIA. This impressive speaker lineup runs from 9am to 6pm on Thursday, June 2 in Hall Y5. Please check the ISC’22 website for a more detailed agenda with speakers and times.
Arm is also participating in two mini-workshops. Anastasia Stulova is presenting at the Third Workshop on LLVM Compiler and Tools for HPC (Thursday, June 2, 9am-1pm, Hall Y8). And Conrad Hillairet is an organizer for the Workshop on Software Co-Design Actions in European Flagship HPC Codes (Thursday, June 2, 2-6pm, Hall Y12).
AHUG is also hosting a Birds of a Feather: Accelerating Arm for Zettascale, which includes a presentation from Roxana Rusitoru. This event takes place on May 30 from 1 to 2pm in Hall E. As the name implies, this BoF will focus on hardware acceleration technologies you can use to speed up your HPC applications on Arm. Finally David Lecomber of Arm will present “The New Era of Innovation and Performance for HPC” on Monday, May 30 from 5-5:20pm in Hall J, Booth J901.
We are very excited to be returning to the first in-person HPC event in over two years. And we cannot wait to see you. Please stop by our booth or join us at our sessions.
