Open Source Distributed Computing Software

Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in service architectures. Features include both the collection and lookup of this data. If you have a trace ID in a log file, you can jump directly to it. Otherwise, you can query based on attributes such as service, operation name, tags and duration. Some interesting data will be summarized for you, such as the percentage of time spent in a service, and whether or not operations failed. The Zipkin UI also presents a Dependency diagram showing how many traced requests went through each application. This can be helpful for identifying aggregate behavior including error paths or calls to deprecated services. Applications need to be “instrumented” to report trace data to Zipkin.

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.

Joone is a neural net framework written in Java(tm). It's composed by a core engine, a GUI editor and a distributed training environment and can be extended by writing new modules to implement new algorithms or architectures starting from base component

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

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.

Jadex is a Belief Desire Intention (BDI) reasoning engine that allows for programming intelligent software agents in XML and Java. The resoning engine is very flexible.

OpenHMS brands a collection of projects and many subprojects developed by Health Market Science. This is a robust collection of development libraries, APIs, and tools oriented around data manipulation and professional software development.

VJDBC (Virtual JDBC) is a JDBC type 3 driver which provides efficient tunneling of JDBC commands/results over different communication protocols (RMI, HTTP, HTTPS ...).

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.

FRODO is a Java platform to solve Distributed Constraint Satisfaction Problems (DisCSPs) and Optimization Problems (DCOPs). It provides implementations for a variety of algorithms, including DPOP (and its variants), ADOPT, SynchBB, DSA...

MARF is a general cross-platform framework with a collection of algorithms for audio (voice, speech, and sound) and natural language text analysis and recognition along with sample applications (identification, NLP, etc.) of its use, implemented in Java.

The XPS is a scalable platform for meta-programming and domain engineering. It provides a virtual machine, compiler, and runtime library that make it possible to efficiently develop, debug, and run programs based on XPL (eXtensible Programming Language)

The DBE Studio is an Integrated Development Environment (IDE) for the Digital Business Ecosystem (DBE). It includes eclipse plugins that allow business services to be analysed, and corresponding software services to be defined, developed and deployed.

A framework to run MATLAB programs as batch jobs. Features a structured input description, integrity constraints and GUI.Independent parts of a job can execute in parallel on a cluster computer. Developed at Freiburg Brain Imaging (FBI) - http://fbi.uniklinik-freiburg.de/

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.

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).

The Sapia Open Source Organization intends to offer reusable, well-documented Java libraries. Conciseness, elegance, ease-of-use, to name a few, are goals we are aiming at.

Load4J provides a framework for developing and running stress tests. The framework itself is a scalable distributed system to based on Java RMI. Setting up stress tests of your own requires the development of Java classes.

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.

A Java middleware API supporting broker-less, type+topic-based publish/subscribe and request/reply messaging for both intra- and inter-application, object-level communication. Broker-less: messages are transmitted directly between eBus applications. There is no message broker (i.e. server) in between. Type+topic addressing: eBus clients subscribe to a message class (type) and message topic, providing stronger typing than just topic-based subscriptions. Object-level communication: eBus delivers messages directly to client objects, not to a client process.

Atomatrix is a multithreaded execution system of atomic matrices with a dynamic compiler and a network eviron. It is the next generation object-orientated environment. XML, MUD-OO CLI, GnucDNA support, windows and many subprojects are built-in.

A C++ framework utilizing Design Patterns for creating Linux and Windows communications applications that contain Dialogic® products. Includes media and network classes (analog, digital, SIP, H323), multithreaded event handling, distributed app support.

Alternative implementation of Spring framework remoting subsystem that supports different schemes of remote communication between client and server (1-1, 1-many, dynamic services discovering).

DropboxMQ is an implementation of the Java Message Service API that uses a shared file system to store and distribute messages. A dropbox is a set of shared directories that relies on atomicity of file move operations to settle contention for messages.

FpgaC compiles a subset of the C language to net lists which can be imported into an FPGA vendors tool chains. C provides an excellent alternative to VHDL/Verilog for algorithmic expression of FPGA reconfigurable computing tasks. More info in wiki.
