Seismic Shifts: Challenges and Opportunities in the Post ISA Era of Computer Systems Design

Series: CSA Distinguished Lecture

Speaker: Prof. Margaret Martonosi, NSF (USA) and Princeton Univeristy

Date/Time: Jan 06 14:00:00

Location: CSA Seminar Hall (Room No. 254, First Floor)

Faculty Advisor: R Govindarajan

Abstract:
For decades, Moores Law and its partner Dennard Scaling have together enabled exponential computer systems performance improvements at manageable power dissipation. With the slowing of Moore/Dennard improvements, designers have turned to a range of approaches for extending scaling of computer systems performance and power efficiency. These include specialized accelerators and heterogeneous parallelism. Unfortunately, the scaling gains afforded by these techniques come with significant costs: increased hardware and software complexity, degraded programmability and portability, and increased likelihood of design errors and security vulnerabilities. The long-held hardware-software abstraction offered by the Instruction Set Architecture (ISA) interface is fading quickly in this post-ISA era. The talk will cover a range of design opportunities and challenges, with a particular emphasis on my groups recent work on automated full-stack verification, security analysis, and the surprising alignments between full-stack issues in both classical and quantum computing systems.

Speaker Bio:
Prof. Margaret Martonosi leads the US National Science Foundations (NSF) Directorate for Computer and information Science and Engineering (CISE). With an annual budget of more than $1B, the CISE directorate at NSF has the mission to uphold the Nations leadership in scientific discovery and engineering innovation through its support of fundamental research and education in computer and information science and engineering as well as transformative advances in research cyberinfrastructure. While at NSF, Dr. Martonosi is on leave from the Compute Science faculty at Princeton University, where her research interests are in computer architecture and hardware-software interface issues in both classical and quantum computing systems. Dr. Martonosi is a member of the U. S. National Academy of Engineering. She is a Fellow of the Association for Computing Machinery (ACM) and the Institute of Electrical and Electronics Engineers (IEEE). Prof. Martonosi received the ACM-IEEE CS Eckert-Mauchly Award, the highest award in the Computer Architecture area, in 2021.
