Open Source C++ Symmetric Multiprocessing (SMP) Software

BRL-CAD is a powerful cross-platform constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing for rendering & geometric analyses, network distributed framebuffer support, image & signal-processing tools.

System Stability Tester is a multi platform open source clone of SuperPI and comes with a GUI and a CLI. It can be used for CPU and RAM burning, stressing and benchmarking.

Systray application that manages affinity and priority settings of Windows programs based on user defined profiles. Affinity profiles may specify either physical CPUs or logical CPU identifiers that expose eventual asymmetries in the system.

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

Enable CUDA on AMD/ATI graphic cards

The Trion Object Oriented Operating system is an OS that is designed to meet the needs for the 21st century, with a kernel written in C++ and modelled in UML, and lots of features. The project is run by a team of OSDev.org community members.

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

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.

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.

New programming language for SPS devices like Amtel Controller . The basic element of this language will be small Moduls of Code which work parallel (Multitasking). A Module can work indepent or with addiction to other Moduls.

PARASOL is a C library for implementing simulations of computer systems. It supports a simulated, user-configured, multiprocessor environment on which user-written software (in C or C++) is executed.

Relacy is a framework for agent-oriented programming in C++. Agents are autonomous objects, they interact fully asynchronously with messages. Relacy provides means for defining user agents and messages, as well as runtime system.

h264 Decoder optimized for exposing ILP to the VEX (VLIW Example) system.

OSlash is a c++ framework for developing decentralized cloud computing services. It includes a programming environment and virtual machine for assembling networks of processing nodes coordinate their operations through message passing.

Usage: parexec NUMTHREADS where NUMTHREADS is the number of commands you want to execute in parallel The commands are read from stdin. Empty lines are ignored. Lines containing a single `-' instruct parexec to wait until all previous commands have finished before starting to execute further commands. When sending a SIGINT to parexec (usually done when you hit CTRL-C) it will wait for currently running processes, but if they are done parexec will exit ignoring all the following commands. When sending a SIGQUIT to parexec (usually done when you hit CTRL-\) or by sending SIGTERM to parexec (e.g. with kill parexec_pid) it will terminate the running processes immediately and exit. After the start of parexec your shell window will be split up horizontally into NUMTHREADS sections. Each section containing the output of one command (which will scroll away as your command writes too much) and a status bar.

xSTreamC is a streaming language developed by STMicroelectronics to support the mapping of data intensive streaming applications on distributed multiprocessor SoCs. A compiler and a simulation library are provided.
