Sampa is a collection of research projects aimed at making computer systems faster, more reliable, more energy efficient, supporting and motivating new applications. We are part of the Computer Science and Engineering Department at the University of Washington.

The nature of the research problems we are interested in is inter-disciplinary and so are we. Our projects include innovation in architecture, operating systems, compilers and programming languages.

We have strong ties with the WASP group at UW-CSE.
