Current AHUG Directors (2023-2024)

Simon McIntosh-Smith (Managing Director)

Simon McIntosh-Smith is a full Professor of High Performance Computing at the University of Bristol in the UK. He began his career in industry as a microprocessor architect, first at Inmos and STMicroelectronics in the early 1990s, before co-designing the world’s first fully programmable GPU at Pixelfusion in 1999. In 2002 he co-founded ClearSpeed Technology where, as Director of Architecture and Applications, he co-developed the first modern many-core HPC accelerators, as used by Tokyo Tech to build Tsubame 1.0 in 2006. He now leads the High Performance Computing Research Group at the University of Bristol, where his research focuses on advanced computer architectures and performance portability. His association with Arm in HPC began as far back as 2009, which in 2013 led to his membership of the Mont Blanc 2 Arm HPC project run by BSC. In 2016 he led the successful bid by the GW4 Alliance along with the UK’s Met Office and Cray, to design and build “Isambard”, the world’s first production, Arm-based supercomputer. In 2020 Isambard received a major upgrade, making it one of the largest Arm-based systems in the world, also adding Fujitsu’s A64FX CPUs, and the latest CPUs and GPUs from AMD, Intel and NVIDIA.

Eva Siegmann (Associate Director)

Eva holds a Ph.D. in Applied Mathematics and since 2021 work as lead research scientist at the Institute for Advanced Computational Science (IACS) at Stony Brook University. She is heavily involved in research computing on campus and one of her main responsibilities is the Ookami project, which as an NSF funded computing technology testbed with Fujitsu A64FX processors. The system is used by researchers worldwide. Dr. Siegmann’s responsibilities include scientific user support, outreach, disseminating results, collaborations with other research groups, and project management.

Before her position at the IACS she worked as senior scientist at the RCPE (research center pharmaceutical engineering) in Austria. There she worked on various simulations in the field of pharmaceutical engineering and collaborated closely with industry. Together with her team she developed a GPU based discrete element method (DEM) software used for simulating granular matter. This software was also coupled with a commercial computational fluid dynamics (CFD) solver to enable the simulation of multiple phases interacting.

Filippo Spiga (Associate Director)

Filippo is member of the NVIDIA EMEA HPC team working as HPC Developer Relations manager for Arm CPU and GPU. His GPU journey and appreciation for Fortran started back in 2009, at the time of the first GPU Tesla architecture during the early years of CUDA. He is also involved in growing and nurturing a healthy HW and SW ecosystem of GPU-accelerated Arm-based systems, including NVIDIA Grace Superchip. Prior NVIDIA, Filippo was Staff Research Engineer at Arm Research in the Software and Large-Scale System team. Before Arm, he worked for 5 years at the Research Computing Services of University of Cambridge as Head of Research Software Engineering leading several HPC projects both with academia and private companies. Since January 2020 he is member of the EPSRC e-Infrastructure Strategic Advisory Team (SAT) which is an advisory body for UK e-Infrastructure strategy (HPC, AI, Cloud and Software). He is an active member of the HPC community and he has been involved in the HPCAIAC Student Cluster Competition since many years.

Personal Statement of Interest: My journey into Arm started ~2015 using the E4 ARKA platform. Since first 64bit Arm SoCs became available, I have managed to (almost) try them all. My interest in Arm gave me the opportunity to build a network of professional connections and great friends. I feel part of this vibrant community and I want to contribute back to shape AHUG next chapter. Arm is already a success in HPC, if I am selected as an associate director, I am eager to dedicate time and enthusiasm to grow the community and drive knowledge exchange activities for the benefit of all members.

Miwako Tsuji (Associate Director)

Miwako Tsuji is a research scientist at the RIKEN Center for Computational Science. She received master and PhD degrees from the Information Science and Technology department at Hokkaido University.

At RIKEN, she is a member of the Flagship 2020 project, which conducted the design and development of the supercomputer Fugaku. Her current research interests are programming and performance models for large-scale high-performance computing. She is a coauthor of the ACM Gordon Bell Prize in 2011.

Eric Boyer (Secretary)

Eric is the HPC HPDA IA project manager at GENCI (“Grand Equipement National pour le Calcul Intensif”).
