OSADL Project: Realtime Kernel Live CD
To evaluate the performance of a Realtime Kernel is a demanding task. This project was launched to assist the production of comparable benchmarks on as much different hardware platforms as possible. The need of unexperienced users to get a first impression of a Realtime Linux system was a second incitement to start the project.
The result is a Live CD based on Knoppix and containing an up-to-date Realtime Kernel as described in the corresponding OSADL project.
The system is directly booted from the CD. An automatically started benchmark tool will run a measurement of the scheduling latency during one minute. To simulate high system stress, a CPU load of nearly hundred percent is produced by a tool called hackbench. The result is visualized in a GNUPlot diagram marking the worst-case scheduling latency.
To see the results of the Realtime Kernel measurements on your own platform please follow these steps:
