Event Summary

Arm-based processors have gained substantial traction in the HPC community. Sandia’s “Astra” reached #156 on the Top500, and projects like the Japanese Post-K “Fugaku”, European Mont-Blanc, U.S. DOE Vanguard, and UK GW4/EPSRC are strong proof points. HPC system integrators like Atos, Cray, Gigabyte, and HPE have Arm commercial offerings, but will Arm become an HPC leader? This BoF brings together experts and luminaries to share their experiences with Arm, discuss the remaining technical and ecosystem challenges, consider the role of codesign in HPC, discuss progress, and lay out a vision for the future state of Arm in the HPC community.

[55min] Panel Discussion

Interactive discussion with leaders in the Arm HPC space.

Rui Oliveira, University of Minho, INESC TEC

Rui Oliveira is a Professor at University of Minho and member of the board of INESC TEC, Portugal’s largest ICT research center. His research interests include large scale data management and privacy-aware data processing. Since 2017, he’s been in charge of setting up MACC, Portugal’s supercomputing center, and is an appointed expert to the EuroHPC Joint Undertaking.

Simon McIntosh-Smith, University of Bristol, GW4

Simon McIntosh-Smith is a Professor of High Performance Computing, and PI of the Arm-based Isambard system. He’s been working on Arm in HPC since 2012, when he was a partner in the European Mont Blanc project.

Mitsuhisa Sato, RIKEN Center for Computational Science

Sato is deputy director of the RIKEN Center for Computational Science, and Team Leader of the Programming Environment Research Team. He is also a deputy project leader and the Team Leader of the Architecture Development Team in the FLAGSSHIP 2020 project that developed the “Fugaku” system.

Andrew Younge, Sandia National Laboratories

Andrew J. Younge is a Senior Member of Technical Staff in the Scalable System Software department at Sandia National Laboratories. He currently serves as the Lead PI for the Supercontainers project under the DOE Exascale Computing Project and is a key contributor to the Astra system, the world’s first supercomputer based on the Arm processor deployed under Sandia’s Vanguard program.

Dirk Pleiter, Forschungszentrum Juelich

Dirk Pleiter leads a research group on “Application oriented technology development” at Juelich Supercomputing Centre. He is currently involved in different projects, where Arm technology plays an important role, including EPI and the Open Edge and HPC initiative. His team operates a 16-node cluster based on Hisilicon Hi1616 processors as well as a 4-node cluster based on ThunderX2 processors.

Keith Obenschain, U.S. Naval Research Laboratory

Mr. Keith Obenschain is a Computer Scientist at the The Laboratories for Computational Physics and Fluid Dynamics at the Naval Research Laboratory. He is currently investigating emerging architectures for DoD HPC applications.

Guillaume Colin de Verdière, CEA

Guillaume graduated from ENSCP (Chimie ParisTech) in 1984 and got his PhD in 2019 (subject was: Searching for the highest performance for simulation codes and scientific visualization). He has been a CEA staff member since 1985. After contributing to large scientific codes for 7 years, he has been deeply involved in post-processing software with a focus on visualization and I/O. Since 2008, his activities are on investigating new architectures for next generations of supercomputers and foresee the impact of such architectures on scientific codes.
