ProActive

ProActive is the Java GRID and Cloud middleware library (with Open Source code under GPL license) for parallel, distributed and multi-threaded computing. With a reduced set of simple primitives, ProActive provides a comprehensive API to simplify the programming of Grid Computing ... [More] applications: distributed on Local Area Network (LAN), on clusters of workstations, or on Internet GRIDs and Clouds. ProActive is only made of standard Java classes, and requires no changes to the Java Virtual Machine, no preprocessing or compiler modification, leaving programmers to write standard Java code.

inferno-npe

My experimentation tree. The goal of this system is to be a "living" inferno tree accessible to people new to the community. With that in mind I want to explain the system in a way that people outside the systems software research community can understand. I'd also like it to encourage ... [More] open development and experimentation like Caerwyn's Inferno Programmer's Notebook. Eventually I want it to be a common source for Inferno folks to keep an unstable tree with common signers and ndb/locals. That way people can see, upload and look at what everyone is working on. I'm also going to add a set of scripts to allow the quick bringup of a variety of different types of inferno installs(i.e. starting with fs, auth and cpu and moving towards something more buzzwordy like a "cloud" system). I'd also l [Less]

inferno-owen

A collection of computers can share computational and other resources to form a grid. Owen™ is a labour exchange for a computational grid. Workers make themselves available for work at the exchange. Jobs to be done are posted at the labour exchanged, subdivided into smaller, potentially ... [More] concurrent work tasks. Tasks are allocated to suitable available workers. By running a worker per node or per processor, the tasks are done in parallel on all available nodes. Owen tabulates the results from each node and a post-processing step can combine the results at the end of the job. Typically the worker software is run on a collection of Windows PCs or UNIX/Linux workstations, and the scheduler is run on a server somewhere. Owen is resilient to failures of workers, and the scheduler saves its state to allow it to be restarted elsewhere if the original scheduler machine fails (although that procedure is not yet automatic). Owen is an Inferno application written in the concurrent programming language Limbo. The implementation is unusual. The labour exchange is a file server. Jobs are submitted, and workers obtain work, by reading and writing those files (following a particular convention). Owen itself provides distributed computation, but workers (and thus the jobs they do) can access other resources using standard resource-sharing operations in Inferno, to build a complete grid. Owen relies on the portable system environment provided by Inferno on Windows, Linux, Solaris, IRIX, etc., and on Inferno's support for implementing distributed applications as file servers.
