Sprite Distributed OS gives one system image to/over a networked cluster of workstations, research project, Berkeley, John Outerhoust group; high file system performance via client and server caching, process migration to use idle machines; testbed for research in file systems (log-structured, striped, RAID), crash recovery.
Hurricane hierarchically clustered OS implemented on Hector multiprocessor; manages system resources in clusters, using tight coupling within clusters, loose coupling across clusters. Succeeded by Tornado.
Tornado Object-oriented operating system for large-scale shared-memory multiprocessors. Minimizes data sharing via careful design: often eliminates data sharing even when sharing appears natural. Successor to Hurricane.
GLUnix Global Layer Unix; technology trends in high-speed, low-latency LANs suggest convergence of hardware in Massively Parallel Processors, MPPs, and Networks of Workstations, NOWs. Relative to many MPPs, NOWs offer more cost-effectiveness and scalability, and less hardware and software development time. Soon, the main difference between NOWs and MPPs will be OS software.
AgentOS Mobile agent system for ubiquitous computing; new way to cope with the wide-area, large-scale ubiquitous computing environment of near future. Allows access to personal and collaborative computing services anywhere, via varied desktop and mobile computing devices.
Hive Distributed Unix operating system for Stanford FLASH multiprocessor; survives hardware and software faults, performance near commercial Unix. Arranged as internal system of independent kernels (cells) for reliability, scalability.
AgentOS: Agent-based Distributed Operating System for Mobile Networks Agent-based communication models show great promise to operate in unpredictable, metamorphic environments, such as mobile computing networks. Excellent basic explanations, clear arguments, well reasoned; from Crossroads, ACM student magazine.
WebOS Gives distributed OS services needed to build applications that are wide-area, highly available, incrementally scalable, dynamically reconfiguring, with mechanisms for: resource discovery, global namespace, remote process execution, resource management, authentication, security.
XOS Distributed operating system, to be fully object-oriented, preemptively multithreaded/tasked, event/message-driven. Little code yet, but design documents and links are interesting, useful reading.
AtomsNet Modular object-oriented application to index files across networks. Consists of plug-in type data retrieval system, webserver, peer-to-peer connections for network-wide information gathering, retrieval; has features of OSs, database management systems, distributed networking. [Open Source, GPL]
Institute for Distributed Systems: IVS Researches distributed and realtime operating systems, communication, software engineering. Part of Department of Computer Science at the Otto-von-Guericke-University of Magdeburg. Some information on site not in English.
Quarks Simple, yet efficient distributed shared memory (DSM) system; a user-level library plus header files supports DSM on groups of Unix workstations. Runs on 4.3BSD/M68k, HP-UX/PA-RISC, IRIX 5.2/MIPS, SunOS 4.1/SPARC. [Open Source, public domain]
MOSIX Software package to enhance Unix kernels (7 so far) and Linux with cluster computing abilities. Lets any size cluster of x86-based workstations and servers work cooperatively as if part of one system. [Open Source, GPL]
Plan B Operating System An operating system that lets applications be built simpler. The system selects and combines resources from the network semi-automatically.
E1 A distributed operating system based on the concepts of object replication, component model support and persistence. It consists of a L4 microkernel and a set of distributed objects acting at the user level. [Open source]
SUMO Support for Multimedia in Operating systems, Lancaster University: microkernel OS with facilities to support distributed realtime and multimedia applications and ODP-based multimedia distributed application platforms.
YouOS Allows running diverse programs in web browser, integrated program development and management, based on HTML and JavaScript. Descriptions, FAQ, weblog, forum, developer support, tutorial, policy, contacts. Open source.
The V Distributed System Research OS for a cluster of computer workstations connected by fast network; structured as a small distributed kernel, and set of service modules, runtime libraries, and commands. Stanford University.
