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

   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.

   Ep 22: Measuring Datacenter Efficiency and Visioning the Future of Computer Architecture with Dr. Babak Falsafi, EPFL

   Dr. Babak Falsafi is a Professor at EPFL, the founding president of the Swiss Data Center Efficiency Association, and the founder of EcoCloud, an academic consortium focused on sustainable IT. His contributions to computer architecture include the invention of spatial and temporal memory streaming (SMS prefetchers) found in ARM cores and laying the groundwork for fence speculation by defining memory ordering requirements in modern CPUs. He is a key figure in cloud-native server design, with his work forming the foundation for the first-generation Cavium ARM server CPUs. He is a former chair of the SIGARCH Executive Committee, a recipient of the Alfred P. Sloan Research Fellowship and a Fellow of both the ACM and IEEE.

[…] And again, we can quibble over exact definitions, but roughly let's say that's what we are talking about. If you extrapolate the growth of model sizes over the last five years from the very first transformer paper to where we are with Gemini 3.1 or whatever, model sizes have been doubling every two to three months. And I'm going to say model size is a proxy for the computer world as well. And so on one hand, you have the demand for computing doubling every two to three months. On the other hand, you have the supply for computing at best doubling every two to three years. And we all know that Mursula is dead and we need to kind of do more things to kind of do all of that. […]
