OSADL on realtime Linux determinism

The Open Source Automation Development Lab has posted a press release celebrating a full year's worth of testing of latencies on several systems running the realtime preemption kernel. "Each graph consists of more than 730 latency plots put before one another with the time scale running from back to front. A latency plot displays the number of samples within a given latency class (resolution 1 µs). The logarithmic frequency values at the y-scale ensure that even a single outlier would be displayed (for details of the test procedures and the load scenarios please refer to this description). The absence of any outlier in all the very different systems clearly demonstrates that the perfect determinism of the mainline Linux real-time kernel is a generic feature; it is not restricted to any particular architecture". OSADL is an industry consortium dedicated to encouraging the development and use of Linux in automated systems.
