Overview

I'm working towards my PhD with a focus in computer architecture. My advisor is David Wood. Recently, I've been exploring ways to make general-purpose graphics processing units (GPGPUs) easier to program. To test my ideas, I rely on gem5, which is a cycle-level simulator that models a computer. I helped bring up the first version of gem5-gpu, which integrates gpgpu-sim into gem5; this makes it possible to model CPUs and GPUs in the same system. More recently, I've been spending time at AMD Research, where I've made large contributions to a similar tool that adds a proprietary GPU model to gem5—an open source version is now available.
