RTEMS on multi-core/multi-processor

AFAIK currently RTEMS has no awareness of multicore processors. If you 
have multiple execution units in your system, you might run a separate 
instance of RTEMS on each of these cores, and couple them through 
"global" OS objects like semaphores, message queues etc. Then your 
configuration is similar to a system of multiple, loosely coupled 
processor systems.
