Open Source Distributed Computing Software

Tools for the Linux Kernel's network block device, allowing you to use remote block devices over a TCP/IP network. Note that we have moved to github: https://github.com/NetworkBlockDevice/nbd

SocketTest - powerful and small software tool for socket testing. It can create both TCP and UDP client or server. It can be used to test any server or client that uses TCP or UDP protocol to communicate.

Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. Supports clusters up to 2000 nodes in size.

Reliable group communication based on IP multicast and configurable protocol stack

.NET VNC Viewer is a VNC viewer written entirely in C#. It is binary compatible with Smartphones, Pocket PCs and Windows desktops (.NET CF or .NET Framework). I write this because other VNC viewers on Pocket PC do not do full screen and screen rotation.

SQLREST enables access to a relational database as RESTful Web Service. Entities can be queried, created and modified using the HTTP methods GET, POST, PUT and DELETE.

The purpose of the project is to develop a portable programming framework that facilitates distributed and multi-threaded programming for C++, Java, and Python. MADARA was originally developed as an agent-based middleware specifically for real-time, distributed artificial intelligence, but is now more general purpose for distributed timing, control, knowledge and reasoning, and quality-of-service. MADARA is composed of several tools and middleware, and the main entry point into the system is the Knowledge and Reasoning Language (KaRL) Engine, which provides a real-time scripting language for nanosecond execution times hooked into a flexible transport layer for distributed reasoning. The KaRL engine also supports object-oriented C++, Java, and Python programming through Containers, classes that provide abstractions and references for variable location within the KaRL Knowledge Base. This project is currently in process of being ported from http://madara.googlecode.com.

JPPF makes it easy to parallelize computationally intensive tasks and execute them on a Grid.

▪ JMP library allows explicit multiprocessing in Java with API that resembles Java Multithreading which is an essential built-in Java feature. JMP allows running a piece of Java code on a separate process either locally or on remote machine. ▪ If the code in question is not present on the target machine, it will be dynamically uploaded. ▪ JMP allows setting affinity for a new process explicitly instead of relying on the OS. ▪ JMP also contains a simple cluster management / load balancing tool called JMP node. Two of the most obvious JMP use cases are: a. All kinds of data parallelism (exhaustive search algorithms, optimization problems). b. Server-side load balancing between available CPUs. See project Wiki for more.

OpenAOS is a open source project of a platform independent and distributed service for accessing measurement data over a standarisized interface (ASAM ODS) defined by ASAM e.V. (for details please visit standards at www.asam.net).

YaCy is a free search engine that anyone can use to build search the internet (www and ftp) or to create a search portal for others (internet or intranet). The scale of YaCy is limited only by the number of users and can index billions of web pages. In p2p mode it is fully decentralized, all users of the search engine network are equal and it is not possible for anyone to censor the content of the distributed index.

IIOP.NET allows a seamless interoperation between .NET, CORBA and J2EE distributed objects. This is done by incorporating CORBA/IIOP support into .NET, leveraging the remoting framework.

The TclSOAP package provides a mechanism to bind Tcl command procedures to remote procedure calls using the Simple Object Access Protocol (SOAP) and XML-RPC over HTTP. Both client and server code is provided.

Retrieve files from a remote computer using a PDA/Pocket PC running Windows Mobile. Can access remote computers regardless the geographical position. Can work under WiFi, GPRS or any other wireless networks.

An implementation of the Open Group's Application Response Measurement (ARM) Version 4 standard. The ARM standard describes a means of breaking an application down into it's constituent transactions, and measuring response time across multiple tiers.

A distributed, peer-to-peer, server-less communication & messaging solution for JAVA (JMS), C++ and .NET applications, integrates with JBoss, WebLogic & WebSphere. Offers guaranteed delivery, security and transactions. Supports TCP, SSL & HTTP protocols.

OpenMAC is a TinyOS-based implementation of IEEE 802.15.4 MAC layer, which lies at the core of MeshNetics ZigBee stack, and provides basic wireless networking (star,peer to peer) to WSN's. Available for low-power ZigBit modules and Atmel AVR Z-Link Kits

QuickServer is an open source Java library/framework for quick creation of robust and multi-threaded, multi-client TCP server applications. With QuickServer one can just concentrate on just the application logic/protocol on hand.

The BTnode is an autonomous wireless communication and computing platform based on a Bluetooth radio and a microcontroller. It serves as demonstration and implementation platform for research in mobile and ad hoc (MANETs) and distributed sensor networks

Channel is a C++ framework for distributed message passing and event dispatching, configurable with its components (msg ids,routing algorithms...) as template parameters. As a namespace shared by peer threads, channel supports scope control and filtering

Hermes is a P2P middleware. It's not a framework, but it's a shell over the existing frameworks. This shell is made in such a fashion that it's possible to the app developer to change the underlying framework without any changes to his app code.

isectd is a middleware daemon that provides many-to-many client-to-server connectivity. Supports multiplexing requests to multiple server processes over IP networks.

Open, fast, robust grid for distributing computing, processes etc. A great alternative to overpriced commercial products such as DataSynapse. Not constrained by standards: contribute to invent new grid computing.

NGrid is a transparent C# .Net/mono grid computing model. NGrid abstracts the burden of the grid into a simple multithread and garbage collected programming model. NGrid is designed to carry computationally intensive tasks over multiple machines.

Sqlcached is a memory cache daemon, inspired by memcached, but offering more granular control by using SQL interface instead of key-value pairs.
