Whatever may be the limitations which trammel inquiry elsewhere, we believe that the great state University of Wisconsin should ever encourage that continual and fearless sifting and winnowing by which alone the truth can be found. --Report of the Board of Regents in 1849.
ResearchMy research targets the memory systems of multiple- and single-processor computer systems. Memory system design is important because it largely determines a computer's sustained performance. My work emphasizes quantitative analysis (often requiring new evaluation techniques) of system-level (not just hardware) performance.I co-lead the Wisconsin Multifacet Project with David Wood. Multifacet seeks to improve the multiprocessor servers that form the computational infrastructure for Internet web servers, databases, and other demanding applications. Work focuses on using the transistor bounty provided by Moore's Law to improve multiprocessor performance, cost, and fault tolerance, while also making these systems easier to design and program. A recent focus has been Transactional Memory (TM) systems for easing multithreaded programming:
Prior to Multifacet, I worked primarily on the Wisconsin Wind Tunnel Project, which focused on trade-offs for designing cost-effect parallel machines supporting shared memory. |
