Title: Ender’s Game: Architectural Techniques to Develop Scalable and
Secure Memory Systems

Abstract: The emergence of new applications, especially in machine
learning, has increased the demand for scalable memory systems. DRAM cells,
the foundation of modern memory systems, face challenges to meet the
capacity needs of next-generation applications. This scalability issue has
led designers to rethink memory architectures by examining data semantics
and communication costs. Additionally, this shift has prompted memory
security to become a first-order design criteria.

In this talk, I will discuss two recent initiatives from my research group
to address these challenges. The first part of the presentation will
introduce Hotline (ISCA 2024), an acceleration framework that reduces
memory and communication overheads in the training of Deep Learning
Recommendation Models by leveraging data access patterns. While Hotline
effectively mitigates performance overheads, it does not tackle security
vulnerabilities -- a growing concern as the memory footprint of
applications increase. The second part of my talk will focus on memory
security challenges, such as RowHammer, in high-capacity systems. I will
present our work on Scalable and Secure Row Swap (Best Paper at HPCA 2023)
that introduces the Juggernaut attack and proposes cost-effective defense
mechanisms. The talk will conclude with a discussion of the broader
research efforts in my group aimed at improving memory scalability for
next-generation applications.

Biography: Prashant Nair is an Assistant Professor at the University of
British Columbia (UBC), where he leads the Systems and Architectures (STAR)
Lab. Additionally, he serves as an Affiliate Fellow at the Quantum
Algorithms Institute. His research primarily focuses on memory systems. In
recognition of his contributions, he received the 2024 TCCA Young Architect
Award and was inducted into the MICRO and HPCA Halls of Fame. He has also
received the 2023 HPCA Best Paper Award, two IEEE MICRO Top Picks honorable
mentions, and the ECE Graduate Research Assistant Excellence Award from
Georgia Tech.
