Insight Computer Architecture Lab
We study how to build faster, more efficient, and more trustworthy computer systems. Our goal is to generate the insights needed to architect future computers that are more energy-efficient, capable, reliable, and secure.
Research
We work across computer architecture, with a special focus on the performance, reliability, and security of GPUs, heterogeneous systems, and accelerators. Our approach pairs careful workload characterization with new architectural mechanisms and fast, accurate modeling tools. Our work spans:
GPU and Multi-GPU Architecture
Memory hierarchies, caches, interconnects, and bandwidth management for GPUs and multi-GPU systems.
Secure and Reliable GPU Computing
Confidential computing, timing side channels, and resilience to soft errors in GPU-based systems.
Performance Modeling and Simulation
Fast, accurate prediction and simulation of AI workloads on GPUs, multi-GPU systems, and emerging hardware.
Accelerating Emerging Workloads
Architectural and system support for automata processing and other emerging applications on GPUs and accelerators.

Our research has been supported by the National Science Foundation (including an NSF CAREER award), the Department of Energy, Google, and NVIDIA. Our students have interned at AMD, Intel, and Pacific Northwest National Laboratory, and our Ph.D. alumni have gone on to faculty positions and to industry roles at AMD and NVIDIA.
