In the AI space, this revolution is already happening, with many custom hardware designs already available. The Center for co‐design of ARtificial Intelligence focused Architectures and Algorithms (ARIAA) is a DOE/ASCR project lead by Pacific Northwest National Laboratory (PNNL) in collaboration with Sandia National Laboratory (SNL), Georgia Tech (GT), NVIDIA, and Qualcomm. ARIAA’s objectives are to co‐design novel architectures, algorithms, and programming abstractions to enable AI‐based DOE applications and support sparse, explainable, and domain‐informed AI models. Ultimately, ARIAA aims at understanding how AI‐focused architectures can accelerate traditional, emerging, and AI DOE workloads, identifying computational kernels that can be effectively replaced by accurate AI/ML methods, identifying opportunities to leverage AI/ML methods to support computation and data analytics, and understanding and designing AI accelerators for future explainable and domain‐aware AI methods. This talk will describe ARIAA’s novel approach to co‐design of AI/HPC accelerators, programming abstractions, and algorithms and how various technologies are integrated to form and end‐to‐end solution.
Bio: Dr. Roberto Gioiosa is a senior research scientist at the Pacific Northwest National Laboratory (PNNL) in the High‐Performance Computing Group and team lead of the Scalable and Emerging Technology Team (SET). His research interests include operating systems and runtimes, high‐performance computer architectures, memory, and networks, parallel and distributed programming models, resilience, performance and power modeling and analysis, and embedded systems.
Dr. Gioiosa earned his Ph.D. in 2006 from the University of Rome "Tor Vergara", Rome Italy. He has worked at the Los Alamos National Laboratory (LANL) (2004‐2005), the Barcelona Supercomputing Center (BSC) (2006‐2008 and 2009‐2012), the IBM T.J. Watson Research Center (2008‐2009) where he contributed to the development of the Compute Node Kernel for BG/Q systems, and Oak Ridge National Laboratory (ORNL) (2017‐2018).
Currently, his projects include the development of system software for extremely heterogeneous systems, system software for scalable distributed systems, DSSoC design, evaluation of emerging architecture and technologies for exascale systems and applications, and development of operating systems for exascale systems. Dr. Gioiosa leads the DOE/ASCR Center for co‐design of ARtificial Intelligence focused Architectures and Algorithms (ARIAA). He is a member of the ACM and IEEE Computer Society.
