Welcome to the Davis Computer Architecture Research Group (DArchR) website

It’s an exciting time to be a computer architect! For the past 40 years, we’ve relied on Moore’s Law and related manufacturing advances for the meteoric increase in computer performance. However, these advances are approaching their physical limits. To increase the efficiency of our devices and enable novel applications we must architect new hardware and computing systems. Our research targets important end-to-end applications (e.g., big-data analytics, machine learning, and high-performance computing) and develops new hardware, software, and systems to improve their performance increase their scalability. Computing systems’ performance improvements have brought the world amazing things: smart phones, Google search, machine learning, and now it is up to computer architects to enable the next wave of revolutionary applications.

We’re recruiting!

We’re currently building an interdisciplinary research group to bridge the gap between advances in architecture and important new applications. If this sounds interesting to you, DArchR is recruiting new students to work on a variety of projects. If you’re excited about computer architecture research, check out the prospective student page.
