Sorry, I assumed I'd get replies from experienced real-time developers: 1) Determinism - the kernel has predictable and repeatable. It provides for some "deadline" (+/- any jitter). The worst case perfromance is known. 2) Hard Determinism - it MUST meet the deadline 100% of the time - or something blows up! 3) Soft Determinism - it "usually" meets the deadline. When using a "soft" deterministic kernel, what "usually" means needs to be quantified.

I am an experienced Unix developer but new to Linux. I am researching doing a project using Linux. I need hard determinism and am looking at how RT-Linux, LynxOS and others play together. There is a lot of "noise" out there. Is there anyone here that can offer some real guidance rather than marketing hype? ;(
