My Group's Research
We built the NOn-Volatile memory Accelerated (NOVA) file system specifically to expose the performance non-volatile main memory technologies (like Intel’s 3D-XPoint and NVDIMMs). NOVA applies many well-known file system techniques but with an NVMM twist. The resulting file system is faster and easier to use than any other file system available.
Six years before Intel released Optane, we built Onyx, the world’s first publicly demonstrated phase change memory SSD. Onyx and Moneta (Onyx’s cousin) used an FPGA controller and a reengineered software stack to nearly eliminated OS overheads to deliver amazing performance. For several years, Moneta and Onyx were the fastest SSDs (GB-for-GB) in the world.
Non-volatile memory is blazingly fast but tricky to use safely, so we built NV-Heaps to understand the challenges and design solutions. We discovered new kinds of bugs and devised ways to prevent them, so that programmers can build fast, reliable, persistent data structures. Six years later we are still building on the concepts that NV-Heaps pioneered.
Should you trust your SSD with critical data? Will your it keep your secrets? Will it work in space? To answer these questions we measured the performance, reliability, and security of flash memory. Our results changed how governments and companies prevent data breaches and changed how researchers around the world think about flash memory.
SSDs are miniature computers sitting alongside your data. Why shouldn’t they help databases (and other systems) process it? We developed a series of prototype SSDs that integrate complex data processing functions into the SSDs itself. We added support for databases, key-value stores, web search, and more.
How do you make use of silicon you can’t turn on? That is a central question facing processor designers as Moore’s Law seemingly comes to an end. We developed prototype mobile application processor called GreenDroid that leverage “dark silicon” to dramatically reduce energy consumption in smartphones.

Grad Students
Training researchers is my main job, and I’m always looking for new graduate students. If you want to build cool systems (and enjoy some sun), please apply and mention me as a potential advisor.
Teaching
In the Spring I teach CSE91: Building Quadcopters. In 10 weeks, students design and build a small quadcopter from scratch, including the hardware and software. The class covers PCB design and manufacturing, the principles of quadcopter operation, sensor filtering and fusion, simple control theory, and embedded systems programming. It’s lots of fun.
In CSE42: Designing and Programming Electronic Devices, students design, build, and program simple wheeled robots while they learn basic programming in CSE11 (Introduction to Computer Science
and Object-Oriented Programming). Working in the Envision Maker Studio, they design the robots using a custom robot design tool, 3D design tools, and their own creativity. Then, solder them together and program them with Arduino.
About/Contact
Bio: Steven Swanson is a professor in the Department of Computer Science and Engineering at the University of California, San Diego and the director of the Non-volatile Systems Laboratory. His research interests include the systems, architecture, security, and reliability issues surrounding non-volatile, solid-state memories. He also co-leads projects to develop low-power co-processors for irregular applications and to devise software techniques for using multiple processors to speed up single-threaded computations. In previous lives he has worked on scalable dataflow architectures, ubiquitous computing, and simultaneous multithreading. He received his PhD from the University of Washington in 2006 and his undergraduate degree from the University of Puget Sound.
