Dr. Lenoski and Dr. Weber have experience with leading-edge research and practical issues involved in implementing large-scale parallel systems. They were key contributors to the architecture and design of the DASH multiprocessor. Currently, they are involved with commercializing scalable shared-memory technology.

The Psyche project is characterized by (1) a design that permits the implementation of multiple models of parallelism, both within and among applications, (2) the ability to trade protection for performance, with information sharing as the default, rather than the exception, (3) explicit, user-level control of process structure and scheduling, and (4) a kernel implementation that uses shared memory itself, and that provides users with the illusion of uniform memory access times.

Excerpt from Memory Management in Symunix II: A Design for Large-Scale Shared Memory Multiprocessors While various vendors and independent research groups have adapted unix and other operating systems for multiprocessor architectures, relatively little work has been done in anticipation of the software requirements of very large-scale shared memory machines containing thousands of processors.
