SeminarLogo.jpg Speaker: Dr. Simon Moore University of Cambridge Title: Does Rigorous Computer Systems Research Demand Open Source Hardware? Date: Monday, May 13, 2013 Time: 12:30 p.m. (Light lunch will be served.) Room: E-Quad, Room B205 Host: Prof. Ruby Lee Abstract: Computer systems research relies heavily on open source software like the LLVM compiler framework, operating systems like FreeBSD and Linux, para virtualisation like Xen, etc. However, much of this research is bounded by the availability of commodity hardware which provides an unnecessary fixed point in the design space exploration process. In this talk I argue that we need more open source and rigorously engineered hardware platforms to facilitate computer systems research which straddles traditional boundaries. To illustrate the point, the CHERI processor (a 64-bit RISC based capability machine soon to be open sourced) will be introduced together with observations from associated compilation (LLVM based) and operating system (FreeBSD based) research into fine grained sand boxing. By making changes all the way from the gate-level to the application-level we believe that much more secure computer systems can be constructed whilst providing a migration path for legacy systems. Bio: Simon Moore is Reader (Associate Professor in USA terms) in Computer Architecture at the University of Cambridge Computer Laboratory in England, where he undertakes research and teaching in the general area of computer design with particular interests in massively parallel secure computer architecture. Dr. Moore is the senior member of the Computer Architecture research group < http://www.cl.cam.ac.uk/research/comparch/ >. This work was undertaken in collaboration with SRI International.
