Are you talking about time-slicing the CPU so that the two threads appear to be executed concurrently on a single computing resource?  That's an unusual requirement in a real-time system that I've never needed, but RTEMS apparently supports it:

If you're talking about real multi-processing on a multi-core processor then you'll need to research the state of the RTEMS multiprocessor support.
