CSL Retreat 2025

2025 CSL Retreat

Date: May 7th, 10:45 AM – 6:30 PM
Location: 141 Tata Innovation Center (11 E Loop Rd, New York, NY 10044)

The Computer Systems Laboratory (CSL) at Cornell University consists of a dozen faculty and over 60 PhD students working on hardware and software techniques to improve the cost, performance, programmability, reliability, and energy efficiency of future computing and robotic systems. Our research spans VLSI, RTL, architecture, compilers, and programming languages. This retreat brings our community together to share research, explore innovations in systems, and foster collaboration.

Keynote Speakers

Thijs Roumen – Cornell Tech

Title: CAD in the Wild

Abstract: In computational fabrication and manufacturing, we have a long tradition of embracing Computer Aided Design (CAD) techniques to design physical objects we end up producing. Inevitably there is a discrepancy between the idealized CAD and real-world conditions of fabrication. In mass manufacturing, we control every machine and environmental parameter to best approximate these idealized conditions. In all other forms of computational fabrication, be it small batch manufacturing or other forms of local distributed manufacturing, we do not have the means to control these conditions. At the Matter of Techlab, we aim to bridge the gap between ideal CAD models and “wild” real-world conditions by building software that embraces this gap. In this talk, I will demonstrate our vision of “CAD in the Wild” at different stages of the fabrication process: before, during, and after fabrication.

Talk Title: Application-Driven High Performance AI System Design

Abstract: In this talk, we explore the challenges of future system design, focusing on integrating application performance characteristics with emerging technologies to achieve high-performance architecture. We present IBM Vela, a cloud-based HPC system for AI workloads, emphasizing system co-design to approach near bare-metal performance. The talk concludes with research opportunities for future AI system design.

Bio: Dr. I-Hsin Chung, Ph.D. in Computer Science (University of Maryland), is a lead researcher at IBM focusing on performance modeling and HPC/cloud systems. He has contributed to Vela, CORAL, POWER, and Blue Gene and serves as adjunct professor at NYU and Columbia.
