Description
Computer systems consisting of many machines will be the norm within a
few years. However, making a collection of machines appear as a single, coherent
system - in which the location of files, servers, programs, or users is invisible to
users who do not wish to know - is a very difficult problem. LOCUS, a distributed
version of the popular operating system Unix, provides an excellent solution. It
makes a collection of computers, whether they are workstations or mainframes, as
easy to use as a single computer by providing a set of supports for the underlying
network that is virtually invisible to users and - applications programs. This
"network transparency" dramatically reduces the cost of developing and maintaining
software, and considerably improves the user model of the system. It also permits a
variety of system configurations, including diskless workstations, full duplex I/O
to large mainframes, transparently shared peripherals, and incremental growth from
one workstation to a large network including mainframes with no effect on
applications software required to take advantage of the altered configurations.In
addition to transparent, distributed operation, LOCUS features also include high
performance and reliability; full Unix compatibility, support for heterogeneous
machines and systems, automatic management of replicated file storage; and
architectural extensions to support extensive interprocess communication and
internetworking.Contents: The LOCUS Architecture. Distributed Operation and
Transparency. The LOCUS Distributed Filesystem. Remote Tasking. Filesystem Recovery.
Dynamic Reconfiguration of LOCUS. Heterogeneity. System Management. Appendixes:
LOCUS Version Vector Mechnism. LOCUS Internal Network Messages.Gerald Popek is
Professor of Computer Science at UCLA and President of Locus Computing Corporation
in Santa Monica. The LOCUS Distributed System Architecture is included in the
Computer Systems series, edited by Herb Schwetman.
