The HttpKernel component provides a structured process for converting a Request into a Response by making use of the EventDispatcher component. It's flexible enough to create full-stack frameworks, micro-frameworks or advanced CMS systems like Drupal. Every HTTP web interaction begins with a request and ends with a response. Your job as a developer is to create PHP code that reads the request information (e.g. the URL) and creates and returns a response (e.g. an HTML page or JSON string). Typically, some sort of framework or system is built to handle all the repetitive tasks (e.g. routing, security, etc) so that a developer can build each page of the application. Exactly how these systems are built varies greatly. The HttpKernel component provides an interface that formalizes the process of starting with a request and creating the appropriate response. The component is meant to be the heart of any application or framework, no matter how varied the architecture of that system.

This project offers open source implementations for UNESCO/IFIP's Algol 68 (the Revised Report language). The project offers two implementations: Implementation 1 is Algol68G: a recent checkout hybrid compiler/interpreter by Marcel van der Veer, supporting arbitrary arithmetic, partial parametrisation, complex numbers, POSIX threads, GNU plotutils, GNU scientific library, curses, sound, TCP sockets, RegEx and PostgreSQL. Inplementation 2 is algol68toc, a port by Sian Mountbatten of the vintage Algol68RS (UK Defense Research Agency) compiler. The implementation emits C code.

Parallel Events and Asynchronous tasKing Library. Originally combining multi-threading with an efficient I/O event model, it's now more a lightweight object-oriented framework for event-based applications.

The first true nanokernel for x86 that gives a unix prompt on a real bourne shell in respect of all security rules!

This is a library to expose the functionality of the Barrier Synchronization Register (BSR) on IBM POWER Systems in Linux. This facility helps speed up synchronization across large SMP systems.

libctf is a c thread foundation library that extends pthread functionality by providing common utilities for the programmer. This will ease and enhance threaded program development.

CLuMPI (OpenCL under MPI) is an implementation of the OpenCL interface which uses MPI as a back end

Set of programs and scripts that will allow to improve the usage of CPUSET. It includes a "jail" for users to just use on cpuset and sets and permissions management. (See web for more information)

This is an opensource project for the calculation of the mathematical constant Pi. If you are a mathematician or programer please contribute ideas or code for this project. Non professionals are also welcome to contribute.

The Cell Messaging Layer is an extremely fast, MPI-like communication library for clusters of Cell Broadband Engine processors. With it, any Cell synergistic processing element (SPE) can communicate directly with any other SPE, even across a network.

CheckFence is a SAT-based formal verification tool that analyzes C code implementing concurrent data types on multiprocessors (concurrent queues, sets etc.) with respect to a selected memory model.

This software aims at demonstrating that we can easily provide a very small and powerful runtime for running programs that are coded in whatever programming model, but that could be *executed* in a DATAFLOW style. The Dataflow Run Time (DRT) provides the runtime support for that The first benefit of this software is to allow a rapid development of such programs in the context of the TERAFLUX project http://teraflux.eu The runtime API has been designed in such way to allow for a future development of a good compiler that targets such interface on one side, and to allow for a good architectural support of such API too: ideally each function could map to a Thread-Level-Parallelism Instruction Set Extension (TLP ISE).

DistributedCL is a middleware that provides location-transparent GPU processing to applications developed using the OpenCL API. Moved to GitHub. https://github.com/andrelrt/distributedcl

EventMachine is an event-driven I/O and lightweight concurrency library for Ruby. It provides event-driven I/O using the Reactor pattern, much like JBoss Netty, Apache MINA, Python's Twisted, Node.js, libevent and libev. Extremely high scalability, performance and stability for the most demanding production environments. An API that eliminates the complexities of high-performance threaded network programming, allowing engineers to concentrate on their application logic. This unique combination makes EventMachine a premier choice for designers of critical networked applications, including Web servers and proxies, email and IM production systems, authentication/authorization processors, and many more. EventMachine has been around since the early 2000s and is a mature and battle-tested library.

To kill a port, prefix it with a colon. For example: :8080. Run without arguments to use the interactive interface. Run fkill without arguments to launch the interactive UI. Force kill processes that did not exit within the given number of milliseconds. Kill all child processes along with the parent process. (Windows only). Ignore capitalization when killing a process. Note that the case is always ignored on Windows. Suppress all error messages. For example: Process doesn't exist.

The project maily focuses on integrating H.264 on IBM CELL platform.

An easy way to perform background processing in .NET and .NET Core applications. No Windows Service or separate process required. Backed by persistent storage. Open and free for commercial use. Easy to set up, easy to use. No Windows Service, no Windows Scheduler, no separate applications required. Background jobs are regular static or instance .NET methods with regular arguments, no base class or interface implementation required. Once a background job was created without any exception, Hangfire takes the responsibility to process it with the at least once semantics. Although the default installation uses SQL Server and polling technique to fetch jobs, you can leverage MSMQ or Redis extensions to reduce the processing latency to minimum. Background method calls and their arguments are serialized and may overcome the process boundaries. Job filters allow you to add custom features to the background processing in a way similar to ASP.NET MVC action filters.

Your own portable PC system built by integrating existing Open Source components. This mobile metasystem utilizes the internet's web hosting resources and is accessed via any web browser enabled appliance from your home, work, school, library, cafes, etc.

A library that makes writing parallel (multithreaded) for loops in Java 5+ easier. It also supports parallel processing of lists and arrays, asynchronous invocation, progress and completion notification, computation interruption and results merging.
