Cellular Irix is the name of the new operating system for the Origin 200/2000 systems as well as the new Onyx/sup 2/, all from Silicon Graphics Inc. (SGI). The scalability, modularity and non-uniform memory access (NUMA) properties of the Origin system require significant redesign of several operating system subsystems, including the I/O subsystem, the scheduler and the virtual memory system. This paper focuses on the kernel features incorporated into Cellular Irix, the user-level facilities providing access to those features and the system performance achieved.
