Plan 9 exceptionally low-budget SF film "Plan 9 from Outer Space") An {operating system} developed at {Bell Labs} by many researchers previously intimately involved with {Unix}. Plan 9 is superficially Unix-like but features far finer control over the {name-space} (on a per-process basis) and is inherently distributed and scalable. Plan 9 is divided according to service functions. CPU servers concentrate computing power into large multiprocessors; file servers provide repositories for storage and terminals give each user of the system a dedicated computer with bitmap screen and mouse on which to run a window system. The sharing of computing and file storage services provides a sense of community for a group of programmers, amortises costs and centralises and hence simplifies management and administration. The pieces communicate by a single protocol, built above a reliable data transport layer offered by an appropriate network, that defines each service as a rooted tree of files. Even for services not usually considered as files, the unified design permits some simplification. Each process has a local file name space that contains attachments to all services the process is using and thereby to the files in those services. One of the most important jobs of a terminal is to support its user's customised view of the entire system as represented by the services visible in the name space. {Documentation (ftp://plan9.att.com/dist/plan9doc/)} (an FTP server running Plan 9). |
