Ep 23: Cross-stack Design and Tooling for Large-scale Distributed AI Systems with Dr. Tushar Krishna, Georgia Tech

About this episode

Dr. Tushar Krishna discusses the design and tooling for large-scale distributed AI systems.

Dr. Tushar Krishna is an Associate Professor in the School of Electrical and Computer Engineering at Georgia Tech, who holds a Ph.D. from MIT. Tushar’s work shapes how the computing community designs modern large-scale distributed AI systems--spanning specialized accelerators, memory hierarchies, and communication fabrics--and driving design-space exploration with pioneering tools like ASTRA-sim, Chakra, and Garnet. A member of the ISCA, MICRO, and HPCA Halls of Fame, his impactful research has garnered over 21,000 citations and the 2025 DAC "Under 40 Innovators Award." He also actively shapes future AI computing standards as the Co-director of Georgia Tech's CRNCH and co-chair of the MLCommons Chakra Working Group.
