RTEMS C User's Guide
All RTEMS objects which are created with the GLOBAL attribute will be known on all other nodes. Global objects can be referenced from any node in the system, although certain directive specific restrictions (e.g. one cannot delete a remote object) may apply. A task does not have to be global to perform operations involving remote objects. The maximum number of global objects is the system is user configurable and can be found in the maximum_global_objects field in the Multiprocessor Configuration Table. The distribution of tasks to processors is performed during the application design phase. Dynamic task relocation is not supported by RTEMS.
