Darwin


 
1. <operating system> An operating system based on the
FreeBSD version of Unix, running on top of a microkernel
(Mach 3.0 with darwin 1.02) that offers advanced networking,
services such as the Apache web server, and support for
both Macintosh and Unix file systems.  Darwin was
originally released in March 1999.  It currently runs on
PowerPC based Macintosh computers, and, in October 2000, was
being ported to Intel processor-based computers and
compatible systems by the Darwin community.
 
2. <programming, tool> A general purpose structuring tool of
use in building complex distributed systems from diverse
components and diverse component interaction mechanisms.
Darwin is being developed by the Distributed Software
Engineering Section of the Department of Computing at
Imperial College.  It is in essence a declarative binding
language which can be used to define hierarchic compositions
of interconnected components.  Distribution is dealt with
orthogonally to system structuring.  The language allows the
specification of both static structures and dynamic structures
which evolve during execution.  The central abstractions
managed by Darwin are components and services.  Bindings are
formed by manipulating references to services.
 
The operational semantics of Darwin is described in terms of
the Pi-calculus, Milner's calculus of mobile processes.
The correspondence between the treatment of names in the
Pi-calculus and the management of service references in Darwin
leads to an elegant and concise Pi-calculus model of Darwin's
operational semantics.  The model has proved useful in
arguing the correctness of Darwin implementations and in
designing extensions to Darwin and reasoning about their
behaviour.
