CougaarSE is known to run on Sun's JDK 1.5 and 1.6 on Windows, Linux, 
Solaris, and OS X.

We've also run CougaarSE on a Geode 233 MHz embedded CPU with Java 1.5:

CougaarME is no longer supported.  It was a completely separate 
Cougaar-like framework that ran on the Java Micro Edition JVM.

As far as I know, we've never tried running Cougaar on a real-time OS. 
So long as that OS supports Sun's JDK 1.5 or later, I imagine Cougaar 
would be fine.  Cougaar uses Java's standard threading services, so (by 
default) it wouldn't take advantage of the real-time support.

Cougaar's thread pool design may simplify the code changes required to 
support real-time threads; see:
