A comparison Of Hard Real-Time Linux Alternatives

An anonymous reader writes "This study compares the real-time capabilities of various Linux kernels. It was part of a project to upgrade the control software in water-wave generators at research institutions around the world. The results of the study were used by Akamina for the selection of a new RTOS for the control system upgrade of Canada's largest hydraulics and coastal engineering laboratory, the National Research Council Canadian Hydraulics Centre in Ottawa."

Summary: RTAI wins...

It would have been nice to see how all of these stack up to QNX and other real-time systems.

Meanwhile, I'll keep this article in mind for if I can ever get a better job position than "ASP.net slave".

Missing RTLinux

[Anonymous Coward]

How can you do a good comparison of Real Time Linux capabilities, without including RTLinux? RTLinux is used in Bluecat RT, one of the more widely used commercial Real Time linux distros. For that matter, LynxOS would have also been a good one to use. It is difficult to make a comparison of Hard Real Time Linux, when you only have one Real Time Linux version to compare with... odd.
