The Penn CIS Architecture and Compilers Group (ACG) explores a wide range of topics in architectures, compilers, and their intersection. Our work is motivated by the dramatic changes in the way we use machines and the constraints that are imposed on their design. See our projects.

If you are a current or prospective grad student and are interested in our group, please do not hesitate to contact any of us (faculty or students). There are lots of interesting projects going on, and there are many ways to get involved. You may also want to check out the reading group.
