QP real-time event frameworks (RTEFs) provide lightweight, modern, event-driven architecture based on asynchronous Active Objects (Actors) and Hierarchical State Machines. The matching QM model-based design tool and other host-based tools complement the QP frameworks by supporting graphical modeling, code generation, software tracing, and unit testing for event-driven embedded software. Visit https://www.state-machine.com for more information. The QP RTEFs can run on bare-metal...

** Information ** XeroLinux Shifting Focus. This project is now shifting focus to work on a brand new Post-Install *Toolkit*. This might prove to be useful to some.

Custom thread scheduler with custom data-structure and scheduling algorithm. Custom Mutex, Semaphore implementation and asynchronous messaging system that combines Observer and Visitor patterns. System is implemented on top of Windows system and not ported to any hardware, uses Windows thread for context saving. Code also has tested common data-structure implementation.

This project is now in the research and development stage. It is intended for very small microcontrollers with a single processor and represent simple multithreading kernel what written by C language. Is planning create implementations for AVR8 and STM8, may be. Now it is suspended until better time.

Simplest of possible kernel for iterative time division multithreading on smallest AVR boards Arduino. This is a small and adapted part of the future "Like OS".

...The memory model chosen is NUMA without pagination. During the initialization, the memory is divided proportionally for each processor installed on the system. When a thread needs memory, the memory allocator returns a free block of memory depending on which CPU the thread is running. In the same way, TORO can dedicate resources to specific processor, i.e. a FileSystem. This only CPU then can access to this instance of FileSystem. The scheduler is based on the cooperative threading model, therefore due to this design, TORO can migrate threads between CPUs and send messages between threads without using any lock instruction. ...

The Popcorn Linux project is exploring how to design operating system for future multi- and many-core hardware platforms, that can be Instruction Set Architecture (ISA)-diverse, based on the Linux kernel.

Microstate Accounting is a way to determine exactly where a thread is spending its time. This project provides Linux kernel patches to implement microstate accounting.

Implementation of virtual threads for the XS-1. Currently a simple context switching implementation for the XMOS XS-1 architecture (Gn, Ln products). Allows a user to run low speed processes on a single thread using time sliced scheduling.

EQP - Eager Queue Protocol is a protocol that uses broadcasting to schedule processes across a local network of processors. It is intended to replace time sliced single thread scheduling in operating systems like GNU Hurd.

...Graduate Project Project: MyRTOS Team name:Software Craftsmanship Description: pxa255 based RTOS. Preemptive Multi-threading,Priority-base,Round-Robin Scheduling, Thread, Semaphore,Message Mail Box,Message Queue Management Support.

Trio extends the existing Linux scheduler to support proportional-share scheduling using a scheduling algorithm, called Distributed Weighted Round-Robin (DWRR). It allows users to control shares of CPU time for any thread or group of threads.

Cross-Platform System Library is a portable C++ run-time library that provides support for manipulating system resources, such as thread, process, mutex, and synchronize, in Win32 and POSIX(UNIX, Linux, Mac OS X) platforms.

Advanced platform-independant, Object-Oriented threading and synchronization library. Designed and tested under POSIX & Win32 systems. Not just another thread wrapper.
