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:
- Download the ISO image and burn a CD ROM (e.g. using commandline tools like cdrecord or graphical tools such as xcdroast).
- Boot the system from the CD and wait for the test to finish...
Another version of the Live CD, stripped down to the minimum of applications and space requirements can be used for evaluation on embedded systems. This Version is to come out soon.
