Abstract

The Sombrero operating system project is an experiment to investigate the potential of a distributed large Single Address Space Operating System (SASOS) as a computing environment. We are currently prototyping Sombrero on Alpha 21164 based NT systems. The prototype gives NT the ability to manage 8-terabyte data sets across a network in a single distributed address space. This distributed address space supports a mechanism that allows multiple network users to have access to and a consistent view of the same addresses while at the same time being protected from one another's activities. We also propose changes to current stock processor architecture to facilitate the single large distributed address space design.
