Plan9
<operating system> (Named after the classically bad,
exceptionally low-budget SF film "Plan9 from Outer Space") An
operating system developed at Bell Labs by many
researchers previously intimately involved with Unix.
Plan9 is superficially Unix-like but features far finer
control over the name-space (on a per-process basis) and is
inherently distributed and scalable.
Plan9 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.
