Steve Schlosser
Research Scientist
ntel Research Pgh.
I joined Intel Research Pittsburgh in July of 2004, after graduating from Carnegie Mellon University. As a graduate student, I worked for the Parallel Data Laboratory, where my advisor was Greg Ganger. While at Carnegie Mellon, I worked on the Fates Database Storage project, the goal of which is to improve storage performance for workloads that access multidimensional datasets. My dissertation work was on the impact of alternative storage device technologies on computer systems, specifically those based on MEMS. My undergraduate studies were also at Carnegie Mellon, so I've been in Pittsburgh for quite some time, now. I am originally from sunny Columbus, Ohio.

Tom Rodeheffer
Principal Researcher

Before joining Microsoft in 2003, Tom Rodeheffer spent eighteen years at Digital's, then Compaq's, then Hewlett-Packard's Systems Research Center (SRC) in Palo Alto, California. As a researcher and then senior researcher, Tom investigated networks, protocols, distributed systems, hardware-software interfaces, and self-organizing systems. For approximately the final two years, Tom was the assistant manager of SRC. Tom received his B.S. from Ohio State in 1976 and Ph.D. from Carnegie-Mellon in 1985. Tom's research centers on the design and operation of systems of communicating processes, especially when combinations of hardware and software are involved. The essential research problem is how to arrange such a system so as to obtain a desired collective behavior, and Tom is most interested in the design of systems that self-organize and self-manage without human intervention. Specifying a desired behavior is often a problem in itself. Tom likes the practical approach of evaluating designs by constructing models or, where possible, working prototypes. This approach often uncovers additional problems that were not appreciated in the original design.

My current foci include big iron scalability, storage SW/HW performance, server/datacenter power efficiency, and the use of nonvolatile memory in server systems.
Research interests: It's all good. :-)
