Linux is being used already in many areas, commercial and military, that require an RT Env and is nothing new. Spains SH-60B(LAMPS) simulator has been running on an RT-Linux solution provided by Compro Computer Svcs for 3 years now. The marines full motion EA6B flight simulator up at Cherry-Point is now running on an RT-Linux solution also provided by Compro (via DEI). There are many others.

Both of these are using Compros' LCRS (legacy Computer Replacement System) software running on an RT-Linux platform to completly replace exsisting Super-mini computers built by SEL/GOULD/ENCORE back in the 70s and 80s. The Linux boxes that replace these old Real-Time platforms actually run the the leagacy code with no modification using the HARDWARE emulation package "LCRS" in Compros RT ENV.

Imagine being able to roll out one monster Super-mini computer that runs a propriatary RTOS with specialized hardware, and hand carrying in a single Intel or AMD based PC, also with some specialized hardware, loading that proprietary OS and application software on it, and your simulator is running just like it did before. This is something Concurrent/Perkin-Elmer could never even dream of being able to do.

Concurrents RTE is really no different than any private indivual could put together. It's an open source kernel with open source patches. One just needs to know which "patches" need applied to his kernel. When I and this article refer to RT-Linux, we are not referring to RTLinux BTW. At least the last time I avaluated Concurrents RT-Env is wasn't.
