Quartz Enterprise Job Scheduler

Quartz is an enterprise-class job scheduler for integration with stand-alone Java applications and full-scale J2EE applications. Advanced features include clustering and participation in container managed transactions. It is highly scalable, very lightweight, and supports very complex scheduling.

GHC

Haskell is an advanced purely functional programming language. The product of more than twenty years of cutting edge research, it allows rapid development of robust, concise, correct software. With strong support for integration with other languages, built-in concurrency, debuggers, profilers, rich ... [More] libraries and an active community, Haskell makes it easier to produce flexible, maintainable high-quality software. GHC is a state-of-the-art, open source, compiler and interactive environment for Haskell. [Less]

Erlang

Erlang is a programming language designed at the Ericsson Computer Science Laboratory. Ericsson released the entire source code of the Erlang system including extensive libraries of code for building robust fault-tolerant distributed applications.

guava-libraries

The Guava project contains several of Google's core libraries that we rely on in our Java-based projects: collections, caching, primitives support, concurrency libraries, common annotations, string processing, I/O, and so forth.

Racket

Programming language suitable for implementation tasks ranging from scripting to application development, and supporting the creation of new programming languages. It includes the DrRacket programming environment, a virtual machine with a just-in-time compiler, and various other tools.

akka

Akka is the platform for the next generation event-driven, scalable and fault-tolerant architectures on the JVM We believe that writing correct concurrent, fault-tolerant and scalable applications is too hard. Most of the time it's because we are using the wrong tools and the wrong level of ... [More] abstraction. Akka is here to change that. Using the Actor Model together with Software Transactional Memory we raise the abstraction level and provides a better platform to build correct concurrent and scalable applications. For fault-tolerance we adopt the "Let it crash" / "Embrace failure" model which have been used with great success in the telecom industry to build applications that self-heals, systems that never stop.

Inferno Distributed Operating System

Inferno® is a distributed operating system, originally developed at Bell Labs, but now developed and maintained by Vita Nuova® as Free Software. Applications written in Inferno's concurrent programming language, Limbo, are compiled to its portable virtual machine code (Dis), to run anywhere on ... [More] a network in the portable environment that Inferno provides. Unusually, that environment looks and acts like a complete operating system. The use of a high-level language and virtual machine is sensible but mundane. The interesting thing is the system's representation of services and resources. They are represented in a file-like name hiearchy. Programs access them using only the file operations open, read/write, and close. The 'files' may of course represent stored data, but may also be devices, network and protocol interfaces, dynamic data sources, and services. The approach unifies and provides basic naming, structuring, and access control mechanisms for all system resources. A single file-service protocol (called Styx or 9P2000) makes all those resources available for import or export throughout the network in a uniform way, independent of location. An application simply attaches the resources it needs to its own per-process name hierarchy ('name space'). The system can be used to build portable client and server applications. It makes it straightforward to build lean applications that share all manner of resources over a network, without the cruft of much of the 'Grid' software one sees. Inferno can run 'native' on various ARM, PowerPC, SPARC and x86 platforms but also 'hosted', under an existing operating system (including FreeBSD, Irix, Linux, MacOS X, Plan 9, and Solaris), again on various processor types.

ScUtil

Hundreds of functions of a variety of topics, from statistics to string parsing, module utilities to network tools. Everyone's pet library accumulates features over time. My erlang library got big, fast. I often find myself giving functions from it out to other people, and a lot of my other ... [More] libraries are dependant on ScUtil in various ways, so I figured what the hell, let's give it away. This library is believed to be efficiently implemented at all points. Efficiency tips are, however, both appreciated and taken seriously. ScUtil uses the TestErl library for unit, regression and stochastic testing. ScUtil is free and MIT licensed, because the GPL is evil. ScUtil is written by John Haugeland, from http://fullof.bs/ . [Less]

parallel

Explicit and implicit parallel programming in Haskell, using parallel strategies and annotations.

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. [Less]
