"Lineo has released AtomicRTAI, a single floppy disk installation for real-time Linux. AtomicRTAI builds upon an earlier single floppy installation disk previously released by Zentropix. AtomicRTAI includes the latest version of RTAI with auto-clock detection, combined with performance measurement tools and several programs that demonstrate hard real-time Linux operation."

"An included measurement tool can be used to evaluate the key RTOS parameters of context switch time -- the time taken for the CPU to stop running one task and to start running another, and jitter -- the timing variance between individual scheduling points of a periodic task. This allows developers to easily evaluate the performance of RealTime Linux on their own platform without the need to extrapolate figures of merit from existing tests."

"AtomicRTAI also includes LXRT, a feature which allows easy deployment of hard real-time tasks without strict kernel dependencies (see reference, below). Hard real-time tasks can thereby be developed on a desktop PC, using the standard Linux kernel, and then deployed under AtomicRTAI."
